You should check the manual for 4s models sience you use a 4s spur. It says you have to use 2 clutch plates each side. 3s plastic spur just comes with 3 plates
Yes I did you can run 4pads or three pads metal gear on the 4s line says you run 4pads on the 4s line but I did run 3pads on the 3s line and it worked good as well but maybe over time will wear quickly I’m not sure tho it might be the power the 4s line puts out it works on 3s both ways
@@earlmoorhead5555 Thank you. Do you know what the cause was? Mine looks identical to your issue but I’ve not been doing anything that extreme and is fairly new. It bottomed out after a small jump and that was that. Should I look to check/replace anything else before replacing it with a metal spur gear? I haven’t replaced the motor mount yet which I hear is weak. Pricing all the upgrades up and it’s not going to be cheap!
It is good to see that I'm not the only one who checks the tightness of all the bolts !! I check all of mine every 4th run . OCD I guess ! LOL ! Nice job !!
Better just order it mlne had been on back order for two months my local shop just let me know it's still on backorder. Hopefully it doesn't break never get parts lol.
Earl loves that big rock GUY haha. You guys both got me to order one l was just saying. On backorder for two months in PA dose that sound accurate?? Can someone lmk 😢l mean 💪💪LMK YEAH
@@rcguygarage awesome. . . im glad to see he has a big rock as well. . . me being on the big rock team as well and have the same mods done. . . finally not breaking everytime i drive it haha
@@earlmoorhead5555 Earl I use my BR on grass and a few small jumps, what would you say is the ideal pinion size for light bashing? I find the stock 15t a little slow
well i've taken mine out 3 times and we have yet to be able to run both batteries dead...there's always something... I've lost a wheel twice (different wheels) and then the servo died...and now the last time i took it out the spur gear AND the center drive shaft got trashed and i wasn't even bashing it that hard...😒 how can BOTH the center shaft AND the spur gear get eaten on one go?! it should be one or the other right?
@@TechWizMaster Replace center shaft with Aluminum replacement, rocks get lodged between it and the motor heatsink.(design flaw) The wheels coming off is a common problem in some models that didn’t get enough threadlock from factory. There’s videos on the screw that you have to check to prevent that. (the screw that sits inside the slide shaft) For me, mine took HARSH treatment for about 3 months until i stripped the plastic input/crown gears on the rear diff. Got a full metal ARRMA replacement and it hasn’t broke since. My factory spur stripped a little after which was surprising it didn’t go before the diff. I’ve seen a lot say the servo is also the first to go, but somehow mine is still holding up. And trust me, I’ve sent mine flipping, cart wheeling, slamming nose dives from failed backflips on hard dirt, crash into things, slammed on the roof, and it’s still working 😆 This was my first basher ever, and I’d give the big rock a 10/10 for overall durability.
Also really interested to see this as I feel a shock upgrading coming as the next mod to my Big Rock. Can't wait to see you field test the result and report back on how the new shocks have improved the performance for bashing.
The sand and dirt will wear out the plastic spur gear is the issue they all will strip but arrma sells the upgraded metal gear that will last a bit longer but still will wear out over time 👍👍🙏🙏
The proline shocks look great but I just cannot justify the price. Here in the UK they are over £100 for the set. I just got a set of Arrma replacement shocks from jenny's for just over £20 so I could get 5 sets for the same money. I guess it's all relative and depends how far you want to go for upgrades and bling. One of the great things about this hobby you can customise to where you want your truck to be.
I turned my Granite Mega into a 3S. Didn't upgrade the gear housing. So still the stock plastic one. So far no issues with bending or breaking, has enough power it stretched my plastic drive shafts. Not sure why they would put a bendable aluminum one on there when the plastic seems to work perfectly fine.
I hate how loud the steel spur gear is. I purchased the hot racing spur gear and pulled it right back out Lol. I prefer the quiet. Thanks for these videos brother!
I enjoy my big rock, although I have broken a rear turnbuckle trying to do a front flip off my ramp, it’s a tank! Just did another bash video with mine! I’m surprised that’s all that has broken it has taken so much punishment! And keeps coming back for more! Nice video brother👍
What do you do when the plastic u joint on the axel keeps coming seperated?.. Is there a good cvd? Reviews for the gpm ones aren't good.. mine keeps seperating. That's the weakest part for how I bash.
1:05 just a correction Earl that's mod 0.8. I know you just misspoke but just to correct that part. Also is the 57t size the stock size the plastic one was?
That Proline suspension is pretty awesome , i use them on my Senton and they work great. 1 tip i have for you is make sure you tighten the small black cap underneath the spring where the shaft goes through. I didn't do this and blew all the oil out of one of the rear shocks because it was loose.
@@earlmoorhead5555 well maybe it will hold up awhile longer. Had to swap out the motor in the servo yesterday on the big rock it locked up so took a old one out of a traxxas servo and it's working once again lol
I love my "Arrma Big Rock Crew Cab 3S," it's got to be one of the best bashers out there, for people that don't have bucket loads of money. Me & my older brother have got the same model, just that his has got the blue coloured body shell & mines black. 👍 Massive Thumbs-Up my RUclips friend. 👌 👍 Keep up the good work fella.
Some people here locally have the hole in the gear housing under the spur closed with tape. It is said that the sand here kills the spur and motor. After two weeks It killed my big rock motor and trashed the spur and so to another guy bought the same car after two days sand bashing.
I ha e this issue with mine brand new I was In a sand pit car jump not even 2 ft landed I notice 1 of the side lower when I look at it the shock came off from the base I look at the other one was about to come off too I'm like bro brand new and you already broken the suspension so I don't know if that happen to you and you glue them back or should I contact the seller cause I consider that wasn't enough momentum to cause this issue so quick
I didn’t glue mine I ended up replacing all my shocks but yes contact horizon hobby to see if they will cover them as they have a two year warranty on the rc 👍👍
45wt in front and 40wt rear on stock shocks noticeably improved my handling and turning. The way you set it up will give it mushy steering and chassis slap.
@@earlmoorhead5555 awesome!! That's really cool you keep yours clean. I always see people in videos upgrading vehicles and I'm saying clean that out now while you have it apart. I'm hoping to get one of these sooner than later and would definitely keep clean with that dry wash and an old toothbrush or something like that! 😁
@Vape N Clash Nice man, I plan to try them out sometime for sure. I went with the 6s typhon shocks on my 3s and seem to work great too. I ended up going with the hot racing aluminum shock bodies that were about $40 and seem to be decent. But ill definitely grab a set of these someday
I gotta repair mine. Sent it off a big dirt cliff a few times. Makes a really bad grinding noise😂😂, but I hate working on it. Worse designed car every.

I found that adding an extra pad to the front side of the clutch give ideal spur position and more fine slipper adjustability.

Since M2C is now making parts for the 3s line, they should make a metal center drive shaft.

No need to adjust mesh with metal spur??

No issues at all 👍👍
@@earlmoorhead5555 ok got them on my 4s typhon for skate board park ready to make this fly
Whats the verdict in the proline shocks??? I broke my rear shock after a super super soft cartwheel so I need to upgrade the shocks.
I think there should be 3 clutch discs installed with the metal spur gear
Those proline shocks look good on there 👏🏾
Yes hopefully works as good
💯💯💪💪💪
Did you have to upgrade the pinion to steel mod 8
Left the pinion stock
1:05 just a correction Earl that's mod 0.8. I know you just misspoke but just to correct that part. Also is the 57t size the stock size the plastic one was?
I did a slit in the chassis right under the spur gear. Rich Duperbash did it in one of his videos and I decided to try it.

Tighten up the slipper clutch or a bearing going bad those motor bearing fail
