Sir you are a God send you helped the entirety of the arrma 3s platform guys worldwide who needed that question answered don't stop doing you 💯👊🏽
Glad you enjoyed. Like I said it is possible that you could jam that thing in there without the modification and maybe other chassis are different though They all look the same to me but I'd be concerned about ever getting it back out again.
I predicted they would release basically this exact thing (albeit not from a new car, just as an optional upgrade for the pre-Mojave 4S lineup) so I'm pretty stoked to see it fits. I've got a Kraton 4S that I'm definitely dropping this thing into.
Yeah it's possible They will release a several one that doesn't require any modifications but as it stands right now unless I really missed something which I don't think I did I don't think that this module will ever be officially compatible since the chassis needs a little bit of modification to fit well.
Finally ordered all the pieces to completely build the center diff, and I just now obtained the power module housing. This is gonna go on my Typhon that’s running on 4s castle system now. Thank you for this. M2C has motor plates now!
Nice! Let me know how it goes.
@@DoRCJenny’s RC had made everything I’ve done so far possible. I just got confirmation my housing order was successful. So here we go. I’ll try and make a video.
@PrototypeFC3S yeah they definitely are handy!
I was wondering about this since the Mojave came out! Thx for showing us how easy it can be… bye bye to all the center diffs on Jenny’s lol
Yeah it's pretty straightforward process. There are a couple of people that have installed it without modifying the chassis but I don't think I would recommend it. If you can manage to cram it in there it's going to be a pretty fun task getting it back out once the dovetails get loaded up with dirt like they do.
I remember cramming a 4074 in my granite back in the day. I had to remove receiver box to get it out because of the dirt in the dovetails.I think the way you did it is the way to go
Been wondering this ever since the Mojave was announced. Definitely getting this for my Granite. Bye bye stupid slipper clutch!
Yeah I think it's going to be a pretty popular upgrade!
I have one on the way for my granite. I was never a fan of the slipper clutch. Its a pain in the rear literally. Now its gonna have a center diff way better alot more reliable. Granite is gonna be a tank when im done with it. Thanks for the vids.
Yes. The only advantage a slipper clutch has is cost for the manufacturer. Pretty much everything else goes to the center differential.
Hi mate. That's a great video. But could you put part numbers so that I can fit this to my grandson arrma granite. I'm so sick os this slipper clutch 😢
😅😂😂
All you need is the center differential itself the power module and the motor mount plate. You can look at the exploded view for the fee 2.5 outcast 4S and get the part numbers from there.
Definitely going to put one in my 3s Typhon. I fabricated my own slipper eliminator and ran it till the out drive split into 3 pieces. Was looking a replacement slipper or eliminator then ran across this. So yes I will be getting one ASAP!!!
Center differential is the way to go!
I've been thinking of installing it on my Senton 3S. The only thing I am not sure is the holding block size?
I can't remember if it's different or not. Check the part numbers in the exploded view diagrams.
the option to adjust the distance from the pinion through those holes is that without the rear cover the differential does not sit straight and you can adjust the distance incorrectly, so if you put the cover on it is something else and tighten the screws from the engine through those holes and check the distance from the pinion audibly
Yeah you can but it's still going to be a bit of a challenge without actually being able to see the gears at all. It's a nice option though.
Thanks for confirming that the center dif module can fit in the other 3/4 s chasis with some minor modification.
Yeah it's possible it'll fit different chassis differently but I looked and they all basically look the same in that area. It's also possible you could jam the module in there without doing the modification but you may never get it back out again.
I just put this in my typhon 3s. Bummed that it hangs over into the battery tray and loses some of the battery pack space.
That's an interesting observation. I hadn't tried it in the shortest wheelbase one yet so wasn't aware that that happened. Did you notch out the chassis to install it?
All i can say is THANK YOU!!!
Thank you for being part of the channel!
Sweet thank you for letting us know
You're welcome Thanks for watching!
Nice work & no doubt really helpful to those looking to upgrade. You saw it here first! 👍😎👍
Glad you enjoyed thanks for watching :-)
My Outcast 4s is definitely getting this upgrade
Yeah I think the 4s vehicles definitely need it
Oh man even if they do fit in current models, we gotta see V3 Kraton and Outcast 4S rigs with center diff and updated chassis formula! The Mojave chassis is tough as nails!
Yeah Yeah it would be nice to see an updated chassis for those that has the slots and holes already cut for this.
@@DoRC absolutely. This could change their BOOST/MEGA/3S/4S line for good!!
@Krapper515 Yeah I predict a lot of people will be doing this upgrade. I think these parts are going to be out of stock for a long time.
Thanks for pioneering this center diff adaptation hands on!
Was planning on doing this with my Kraton 4sV2, but unfortunately "Horizon's new System" cancelled my Mojave 4s order...😢
I may just order the center diff module for my K4sV2 install it after needed modification, then continue with my 6s Mojave chassis build...
I have a lot of goodies on the way.
That sucks. Yes they also canceled mine but I was able to get it reordered. I'm not sure what's going on with them but hopefully they get figured out eventually.
Dang can't do this on my 6s powered 3s typhon. Won't leave enough clearance for my max 8.
Can you put the Max 8 on the receiver box or will that foul on the body?
@DoRC nah the body is in the way. It's been running 6s with a 2700kv TP 4030 cm in it for over a year now so if anything was gonna happen I'm sure it would have by now.
What ist he part number for the trans assembly?
You can get all the part numbers from the exploded view diagram for the Mojave 4S on either the Arma website or Horizon.
Thanks for this defo getting one for my senton 3s. Bye bye slipper clutch
It's a definite improvement.
@@DoRC just been looking for the parts and came across the arrma red aluminum diff. Is this a worthy upgrade what material is the standard diff.
That's 2 videos in a row you copied, Earl Morehead and Jay Tee. Come up with your own videos, c'mon man
Okay so first of all Earl Moorhead did not provide a solution to the problem he just complained. My video provides a solution and then tests the solution so I don't really think that's a copy.
Second check the time stamps on the differential videos from JayTee and me. Mine came out first :-)
There's only so much going on in the RC world at any given time, there's going to be some overlap. Everyone and their mother with a 4S or 3S Arrma wanted to know if these will fit.
As a noob….what’s the benefit of doing this?
There are two main advantages to a center differential. The first one is the allows you to adjust the fluid in that center differential to tune how the truck behaves. If you run thinner central differential fluid under heavy acceleration the truck will be less likely to wheelie because power will be allowed to bleed off to the front tires. The second and more important benefit is that it allows energy to dissipate through the drivetrain. For example without If you land a jump on just the back wheels when those wheels start to spin up or slow down the entire drivetrain has to take all of that inertia because it's all locked together. A centric differential decouples the front from the rear so that those loads can be dissipated so it really helps save the drivetrain.
@@DoRC Thanks for the detailed explanation. 👍🏻
You're welcome and thanks for watching!
Now I can pull out my mt converted 3s Typhon, and start running it again. I hate no center diff in a 4wd off road vehicle. I've been wanting this mod for 2 years...
Yeah the chassis mod really is not that difficult And maybe it'll fit without the mod on some chassis. I don't think so though as they all kind of look the same from what I'm seeing. You might be able to jam it in there without doing the mod but I'm not sure you'll ever get it back out again
Have you installed? Was it difficult to modify and how do you like the outcome?
You. Are. Awesome.
Thanks:)
Just ordered the center diff module from eBay and I noticed that there are two small gray plastic pieces that come with it have any idea what they are for? Certainly can't figure it out from the picture.
It looks like it's those weird little levers that fold out into the battery tray. I've never really been able to figure out what they're for.
@@DoRC ok thanks it's not just me then.
Nope. Maybe somebody knows what it's for but I've never been able to figure it out. It seems like it should be to allow for different sizes of batteries but it doesn't actually do that.
Anyone done this to a granite yet ?
I think I've seen a couple of videos on RUclips where people did. The basic chassis design is identical between all of the 3S vehicles so it shouldn't be any different than this.
That is so fantastic!! I have a granite I widened with the RPM Typhoon arms that I wanna go 4s with. The only thing I really wish it had is a center differential… I think it’s going to be incredible with a Center diff! Any chance you could link a parts list, or part numbers? Fantastic video! Thanks for doing it!
Just look up the exploded view for the Mojave and you can get whatever part numbers you need there and it'll actually have links to the parts.
@@DoRC sweet! Thanks!!
You're welcome!
When you were doing the swap, do you know if the factory motor mount plate fit in the center diff module? I have a hot racing heavy duty motor mount with the chassis brace
that I’d like to use. I’m guessing the chassis brace will be too long.
@@chriscrisafulli798 I didn't specifically look but I don't think it will. The bearing on the center differential is quite a bit larger than on the slipper clutch so the hole for that is going to be too small on the slipper clutch motor mount plate unfortunately.
Does anyone have the part numbers? I think I found the case but can't find the diff
If you go on the horizon website and open the page for the 4S Mojave about Midway down you'll see an option for shopable exploded view. They have one for pretty much all of their cars and you can use that to find whatever part numbers you need!
@DoRC I did manage to find it. I was having a really hard time finding it using Google but it ended up being easy just navigating from the support link on the website
@BradWorona Nice yeah when vehicles first come out googling new parts can be very hit or miss because until those parts start getting available on third-party sites I think Google has a hard time automatically crawling that information and making it available. It's always best just to go to the support for the product and look up the parts through the exploded diagram.
These are going to be out of stock at Jennys for all eternity.
What did you use to grind down the chassis?
Dremel.
A Dremel with a flap wheel.
@@georgetekbruh he said Dremel like 5 times I knew that he used a Dremel. I meant what attachment.
@@DoRCah the only attachment I don't have.
Yeah fortunately I had just bought a 500 piece attachment kit from Amazon. You can get them for like 30 bucks and they're really handy to have. Nothing in there will last that long but all of the choices means you'll pretty much always have what you need.
THE CASE DOES NOT COME WITH THE RED ALUMINUM PLATE. Ask me how I know. 🤬
That sucks. I'd heard someone else say it did but that's why I said I wasn't sure.
@@DoRC my shop ordered a few of the cases and diffs. We didn’t order plates because the picture of the part number CLEARLY showed a motor plate. Once they arrived, no motor plate.
@@PigglyWigglyDeluxe that's lame
Seems the center diff is currently available via Horizon but the mount plate is on pre order and i couldnt find the modual at all.
That's unfortunate. Yeah I know a couple people had them in their hands but I'm not sure how they got a hold of them. Looks like it's either going to be buying or Mojave or wait for Jenny's for now.
@@DoRC seems it's now available via Horizon for only $14.99
@@franklee6301 for the module?
@@DoRC yup. 4s center differential modual
@@franklee6301 sweet. Have you priced it out with the center diff and the motor mount plate?
what are the parts you need?
You'll need the sentry differential in the center differential housing and the motor mount plate.
Hello! do you really think there is 10 million cst oil in this diff? or did I not understand well? I've finished putting the power module on an Outcast 4s v2 and it seems to me that it inflates the hubs too much on the front, it actually works better but I think it needs a little thicker oil, but on the other hand I'm a little afraid not to force the planetary gears or the central axis...thanks once again
I'm not entirely sure what weight fluid is in there. It might be thinner than that. I wouldn't worry about over stressing the internal gears. I have put pretty thick stuff in quite a few differentials and I've never had a negative outcome because of it. I'd recommend putting a little bit of silicone ear plug in there and see how that works. It'll nearly lock up the center differential but will still give you enough give to protect the drivetrain.
@@DoRC thank you!
@make4all2000 You're welcome :-)
Stock is 500,000 cst im upping to 1million to decrease front tyre ballooning on my senton 3s@@DoRC
Wonder how this will work on the 4S outcast v2. Currently trying to build one and don't have these parts yet so this could be an interesting upgrade to consider.
I don't see why it wouldn't. The Outcast V2 chassis appears identical in that area too What you saw in the video so with the same trimming it should fit just fine.
@DoRC I mean change the handling etc. I city bash and wish this came out when I still had the vorteks! That slipper got replaced 5 times before I sold it.
@DoRC I think the 3s and 4s chassis from arrma are basically the same just SWB MWB LWB and i think an XLWB. Yeah I spent way to long shopping for the MWB. Not sure if it's backorder.
@@Macgyver46 oh well it really depend on what viscosity fluid you put in it. If you go fairly thin it'll make a huge difference. Stick a couple ear plugs in there and it'll behave very similarly to the slipper clutch just with the ability to help save the drivetrain from shock loads.
@Macgyver46 according to my recollection and the pictures I checked they all appear to be identical in that area. That means that you'll probably have the same problem as I did no matter which chassis you're installing it on. Not a hard problem to fix though.
already ordered the parts!
Nice!
How did you take nut off the chassis brace bar?
Not sure what you're referring to. I watched the video and didn't see anything referencing that
@@DoRC 0:17 not the hex screw but the other one screw unless it’s a pin that holds the actual brace to the chassis
Just replaced my Kraton 4s v2 chassis and I noticed the cutout is different amongst a few other changes that appear to have strengthened the weak points. Maybe my new updated chassis is compatible.
Yes the new chassis is compatible with the previous vehicles
Why not just use the Mojave chassis also? The 4s Outcast and Kraton chassis are dirt cheap. Won't the Mojave be the same as the Kraton and only a little longer than an Outcast?
Not sure about the length. I'd have to measure them. Hopefully they'll come out with updated chassis for the other two that already have the updated area for the spur gear
Cool vid, on the flip side yeas it will make the drive train less vulnerable in terms of stress,, BUT it will sacrifice some
Of the snappyness and bitethat you had before = FUN
It can do that but if you're worried about that problem you can just put silicone ear plugs in it and it'll mostly lock it up giving you pretty much that same snappiness without sacrificing the drivetrain protection too much.
Been waiting for a video like this thanks man great vid 👍
Glad you enjoyed Thanks for watching!
Thanks for doing all the work. FIRST!!!
Happy to help and thanks for watching :-)
Bad ass vid dude. I actually swapped my big rock chassis with the Mojave one and everything lines up perfect, I’ll have a vid up on my channel here soon. Side note: the Mojave bumpers also work on the other line. It’s pretty sweet
Nice! Yeah pretty much everything is cross-compatible on the different models. Can make for some pretty interesting hybrids :-) Thanks for watching!
Dont have my vorteks 3s anymore..but hey nice to know it could be an option there😮
Yeah I think we'll see a lot of center diffs adapted to the three and four s vehicles. Thanks for watching!
Owe yeah, switching out the V1 kraton 4s for SURE!! Great video, very helpful.
Thank you!
Thanks for watching!
You are awesome.
Thanks You're awesome for watching!
I want to stuff that in a vorteks 3s blx with a 4074 motor and 150A esc and run it on 4S
Do it!
@@DoRCI know running that on 4S is going to lower my rpm, how far should I gear up to compensate for the lost rpms? Im going from 3S with the stock 3200kv so a rough 35,500 rpm down to a 4S with a 2050kv which will be around 30,300 rpm? Or should I just toss in 4S diffs and cvd’s and run it balls out at 6S?
@thatmadscientistfromny5362 yeah that math seems about right. I would maybe go two teeth on the pinion and see how that goes.
@@DoRCwill 4s front and rear diffs fit my vorteks? Im sure Im gonna grenade the stock 3s diffs in short order and after I get my big bore shocks and cvd’s I want to run my vorteks on 6S and see if it will hold it
@@thatmadscientistfromny5362 yes they will.
nice video, getting into them makes great content!!! 💯👍👍
Yep it's what I love to do! Thanks for watching :-)
Yes thank you! Been waiting for a video like this since the mojave was announced. Definetly going into my outcast! Best wishes from austria
Awesome let me know how it goes! Thanks for watching :-)
Be nice if you could do a weight comparison between the two setups.😁
I think the increase in weight will be negligible. You're only talking about a couple of ounces at maximum. Not something that the vast majority of us would even notice.
Will the 4s axles work on the 3s vehicles? I have a senton we swapped to 4s and it destroys the stock shafts.
I know they will fit the differentials and I think they'll fit the hubs and knuckles. I would check on the 4S parts breakdown and make sure that the bearings are the same size.
@@DoRC are they the same length?
@MudMonsterRacing4 No the arms on the 4S vehicles are longer although the new Mojave arms are only like 93 mm long so those axles might work.
@DoRC if I do the swap I'd have to go to a 17mm hex right?
@@MudMonsterRacing4 Yes. All of the 4S axles are 17mm
My big rock might get a reprieve from the bin now that a center diff will fit
I think it's going to make a lot of people happy!
Honestly, I would have argued against it being that easy! Well done, Sir! I was especially surprised about the center drive shaft fitting without modification! I would love to see you drop this in a Big Rock and give it a proper thrashing! 🤤
@@jerryvolpini7987 I was actually surprised any modification was required at all but I'm glad it was fairly straightforward. Unfortunately I don't have a big rock but I'll definitely be giving this under differential some abuse in the Mojave. Video will be out tomorrow!
Definitely considering this since I put a 6s motor/ESC in my big rock.
That would be a worthwhile upgrade for sure!
Do you think I should throw one in the kraton 4s
Absolutely. The center differential is far superior to a slipper clutch. That's why pretty much all modern RCs that cost more than a couple hundred bucks have them. Very good upgrade.
@@DoRCthank I will be doing that once they are back on stock of course
@lucapoehland1958 definitely a worthy upgrade.
I do appreciate it, that you actually take apart most of the things in your videos just to show the quality, I really appreciate it.
Glad you like it. I enjoy doing it!
Very interesting. It might a great upgrade for my 4s outcast.
Yeah I think this is going to be a required upgrade for the 4S trucks
so I will have to trim my chassis down a bit to fit it?@@DoRC
@@RCPropaganda based on my experience I believe that is best. I was physically unable to get the module to fit into the chassis I tested on and they all appear to be the same in that area. Other people have managed to jam the module in there but I don't think it's a good idea and I think they're going to have a really hard time getting it back out even if it is aligned correctly once installed.
It fits in the Kraton 4S perfect, no trimming needed
@GamezOfWar have you tried to remove it after the dovetails get packed in with dirt?
Can u use the oem 3s motor with the center diff instead of swapping them out
You can use the 3S motor but you have to use the motor mount and module from the 4S as the center diff won't fit in the 3S mount or module.
I think it’s a great set up for parking lot bashing and even a skate park with the on road cars. Good job on that! 🎉
Yeah it certainly won't hurt!
Great video mate I've been asking this question since this centre differential came out. Now would it fit vorteks 4x4 3s and what would the part numbers be for any part change ?. Ps running 4s plus on vorteks 😊
Based on what I was seeing when I looked at various chassis online I believe they're all identical in that area between the 3S and 4S cars up till the Mojave so it should fit the same way as it did in the video. If you look up the exploded view for the Mojave 4s You can find the part numbers on there. Thanks for watching!
Do you think it will fit in the outcast4sv2
I don't see any reason why it wouldn't. They all take the same slipper module and where it installs looks identical on all of the different models. You will likely have to do the same thing I did on this chassis in order for it to fit properly but I don't see any reason why it won't be able to be installed in any of the 3 or 4 s vehicles
Jay tee done this yesterday on a senton no trimming, cool video tho
Yeah but did you notice how he didn't actually show it being installed? I'm sure you can jam it in there if you push hard enough but good luck getting it back out again especially once some grit gets in and does its thing like it usually does in the dovetails. He even said in the video it was super tight. That's not what you want.
I would recommend making the clearance so that it installs easily. If you don't you're probably going to be pretty unhappy when it comes to time to take it out later.
@@DoRC good point, got a new subscriber
@@daig1984 awesome thanks!
Hello! I saw that on the platform I saw that on the 4s v2 platform they say that it goes directly, without any modification to the chassis, what do you think? maybe you can make a video for the chassis of 4s v2..thanks
I don't have one currently but at least in the pictures I've seen of the chassis the V2 Outcast and Kraton appear to look identical to the 3S models. It may be possible to install the differential without modification even on the 3S models as I've seen a couple other people do it but I think creating that extra room will make life a lot easier especially when it comes to taking it back out again.
@@DoRC Thanks for the reply, all good'
Will this fit the big rock 3s and the senton 3s?
Yes it should.
Cool video, You've made me want to do this to my new Vendetta and you used the Infraction as a test which is based off the same platform as my Vendetta. Maybe someday i'll do the Center Diff mod to it plus a 4s system and the metal 4s front
ear diffs. One last thing which new 4s chassis would fit the 3s Infraction\Vendetta.
I think the chassis are different lengths so I don't think either one of them would.
@@DoRC Oh okay, Although i haven't driven mine yet so i don't how it will hold up but i can definitely look into a center diff swap someday if the stock slipper fails. It will just require some mods to make it work.
@@cjchannel12RC Yeah you might find that the on road cars don't really have too much problems and you won't need a center differential but it's always good to have :-)
As always, Scotty...u da man !!💯💪
Glad you enjoyed!
Hi, an awesome video I have a question so if I have the new Mojave 4s 1/8 scale, chassis, will the older model slipper clutch style case fit in the new Mojave chassis. Thanks.
Yes it should fit just fine.
I put a center diff in my k4 a couple weeks ago. I knew it would fit when I compared exploded views
You mean without the rest of the module?
@@DoRC I have the case and the diff. All I need is the motor plate (because the case doesn’t come with one and the plates are still on preorder with no ETA) and I fit it in the chassis with no motor or diff but the case fits and everything lines up. No trimming needed like yours did.
@PigglyWigglyDeluxe Yes without the differential it'll fit fine because you can put it in an angle. With the differential in there it becomes a lot more difficult because the splines on the differential have to line up with this lines on the rear diff input shaft. That's what was binding on me.
So its no longer a friction fit. It easily slides out now after removing the screws. They will iodate the current 4s and 3s to make it compatible. Im sure before xmas
No the fit is pretty much the same as with the 3S ones. When they're brand new they all come out pretty easily. It becomes more difficult as soon as any grit gets in the dovetails. None of them are designed to be a friction fit from the factory though. They're supposed to be held in by the little block that sits in front of them and the latch at the top.
It will be interesting to see if they update the other chassis to be compatible.
only my big rock is getting a diff. the vendettas get spools and the granite will be fine w a slipper
That sounds pretty reasonable. Unless you're having a problem with the slipper the smaller vehicles probably don't need it
@@DoRC thanks for this quick video,, we've been dying to know if it will fit
@@ruuster83 Yeah I've been itching to find out too. I was so curious about this I ended up putting this video out before my first video on the Mojave. That'll be coming out tomorrow so stay tuned!
Going in the 4s kraton for sure 😊
Let me know how it goes!
thaaaaaaank you man!!! 🙏🙏🙏🙏
You're welcome Thanks for watching!
Anyone wanna try on a Typhoon 3s?😁
Based on the way the chassis looks I don't think the process would be any different. All the vehicles other than the Mojave appear to be identical in that area.

My Senton needs that!
Definitely a great upgrade for any 3S or 4S truck
Working phenomenal
Did you do this?
That's great news ) But how about Mojave arms on a bigrock 3s, or maybe typhon. How do they compare in terms of length?
I don't have either one of those but the Mojave arms are approximately 93mm pin Center to pin Center
@@DoRC thanks!!! This helps as well
@T0x1c0v3r You're welcome!
If anyone is curious, typhon/bigrock arms are about 100mm. 4s hubs look like they have a bit more offset, so you may get about the same width, better driveshafts, stronger arms. I`m definitely going this way with my bigrock
Sweet let me know how it goes!
I put it up on FB!
Thank you :-)
Yeeeeeeeessss
Thanks for watching!
Great video, have been thinking about this since they released the 4s Mojave. Question though, can’t you just replace the 3s slipper clutch with the center diff and keep the 3s power module? Does the center diff fit on its own? Then you wouldn’t have to mod the chassis. Would love to know
Unfortunately no. The center differential is quite a bit thicker than the slipper clutch and uses different size bearings. It's got to be the whole module.
You honestly expected it to fit in there??
@@666cemetaryslut that’s what she said
Dope👍🏾
Thanks for watching :-)
Typhon lollll
Typhon?
If i ever go 4s in my granite ill probably do this but i just put the $60 hot racing steel spur/slipper combo in and it seems to be working
Yeah the hot racing one definitely is an improvement over stock!
Can i ask why you'd opt for the hot racing over the arrma steel version?
@@cparch1758 Its not just the spur gear its also a upgraded slipper clutch. The part number is ATF257EX
Sweeet. Why didn't they do this years ago
That I don't know. Given that there are already holes for this module in the 3S chassis they've been planning this for quite some time. Why it took them so long to get it done and why they weren't on at least the V2 trucks I'm not sure. If I had to guess I'd say they had some sort of either supply or internal issue with the system and had to do a redesign or something like that.
