This AAD Suspension kit is a Great Kit along with the Per4mance development Diff brace! The wheel hop is gone and the feel on launch gives me the confidence to absolutely Smash the Gas! The wheelie is cool too! 💪🏼👍😎
Speedy, If you ever drop the cradle again in the future! Just remove the bottom shock bolt and not the two top bolts. Way easier because it’s one bolt and nut, plus the bottom of the shock sits in a cup like pocket. Plus, try placing your floor jack under the coil spring pocket of the Big lower A arm that the coil spring sits in. This will still give you great clearance and way better control over the cradle. And of course do one side at a time leaving the cradle bolts tight on the side you are NOT working on, so it won’t change the thrust angle. This is per Mopar factory repair manual. I did my 2015 Challenger SRT392 last week with all BMR parts and it worked out great. Not a bad job if you take your time and work smart like I know you do. Love your videos, and you should have been the Donut maker without a doubt.
Good suggestion! I considered the lower shock bolt, but if memory serves the car has to be setting on the suspension in order to properly torque that bolt, which is tricky with the car on the floor. At least that's what I remember from doing suspension work on other vehicles.
@@SpeedysGarage , yes but you can torque it while the suspension is loaded on the jack, wheels off! As long as the cars weight is loaded, it doesn’t mean it has to be sitting on the floor. I just picked the car up off the jack stands with the floor jacks in the spring pockets (I used two floor jacks) one per side. That loads the suspension, then do your torquing. You have to have the suspension loaded under cars weight while you torque all of the control links and trailing links, So you must have the wheels off. Same as a Alignment tech would do if he were doing this work for you on an alignment rack. They can load the suspension with wheels off. Just trying to help
Genius! That's a great idea.
Nice, perfect timing, as i just bought this kit for my Redeye, but haven't installed it yet.
Can't wait to see your new times at the track and see if the expense and install was worth it...
Wise choice Speedy I went with the whole front to back set from AAD and it dialed in my alignment dead on and am extremely pleased with the workmanship. Be advised after I changed to the AAD setup I had the original HHP links at 8.5 inches center to center and they still made contact. I put the stock links back on and plan to wait until AAD comes out with theirs.....options are to go with adjustables Make certain you ask for ALL the tabs for alignment shop and give them all the options rather than the standard amount offered. You an tell them apecific alignment specs if you desire. There is room to adjust with AAD parts you will NEVER get with stock
Mine never touched with the HHP links, mine measure 8.25". Yes, this AAD suspension seems to be infinitely adjustable.
Another very informative how to video. Thanks Speedy. Lots of you tubers like to just talk and talk with out showing how to do stuff. It's refreshing to see a car guy working on his ride.
This is a great how to. I’ll be tackling a 15 inch conversion here soon on my charger and I appreciate all of the tips for dropping the cradle 👍🏻
Must have been a Marine, concise and on point
About to do this on my 09 srt8 charger. I got bmr solid subframe bushings as well. I went solid on my g37 and it really tightens up the feel and honestly ride feels better than the worn out oem rubber. Its a pain in the ass but i think its worth it.
Love the content speedy! Giving me many ideas for my Redeye
Last time I dropped the cradle was on my son’s 2010 challenger rt, great video 👍😁
Excellent job brotha, appreciate the video. Need to put a lift in that gorgeous shop of yours. 😉
First off, huge fan of this channel, Speedy has some of the best install content for hemi guys. I've got AADPERFORMANCE setup as well, below is my install notes and feedback.
I have a 2019 Charger 392 with dynamics package (one day ill own a hellcat) but his vids have been extremely helpful across both 392 and hellcat platforms imo!
Sorry for posting a book Speedy, just wanted to share my experience as well.
When I installed the rear upper control arms (forward and rearward) as well as lower rear trailing arms on my 19 Charger 392, I had to go the cutting bolt method. I also did everything with hand tools. You will def feel it next day lol.. It took about 5 hours to do it all. I was hesitant about cutting but in order to do so using a sawzall is purchasing a good set of Diablo 9" blades and installing them teeth facing upwards. I had the car itself jacked up and a smaller jack on the whole spindle assembly to relieve tension and aid with installing bolts. Loosen the bolt that is near the frame as best you can, and it will provide just enough space to get the blade between the bolt head and arm. Cut upwards taking your time, and spray a little bit of lubricant as you go. Don't rush and the bolts will cut off easily. Cutting upwards prevents you from potentially damaging or nicking other frame components/wiring/lines etc. Once the bolt is removed you can then install the new AAD supplied hardware with the bolt head on opposite side for ease of removal without cutting or lowering cradle next time if need be.
If you do it this way, torquing the bolts is still a pain but still possible. I also used BLUE loctite for peace of mind as well as used a paint pen to mark everything for visual inspection after a few hard miles of driving. Take your time, ask Zach or Parker of AAD questions if need be since they are fantastic to deal with.
I've had my AAD parts installed for over a year without any issues. One of the best mods I've done and firms up the rear end in not only straight line but also turns. Wheel hop is gone when it spins even on the crap oem 275 Pirellis. It hooks and just wants to go straight. I had AAD setup the arms with +1 degree of positive camber or basically stock to help with launching.
Lastly, if you have the ability to lower the cradle, do so. It makes the install much easier especially with torquing the bolts. But there is a second way as well as mentioned above if you decide to do so. AAD provides instructions for both.
I also have pics and brief writeup on hellcat.org forums under Charger 392 thread showing my AAD install.
The lower trailing arms are very easy. 30-45min job. Its the upper rearward and forward arms that are time consuming. I can't comment on the toe arms since I haven't installed yet. Good luck with the mods
Bryson you need to install this on your MOPAR!!
Hey Speedy, great content as usual! I am getting ready to tackle this install, and was hoping you can clarify your statement with what you did with the four 18mm cradle bolts as explained beginning at 3:00. I just want to make sure I am following you clearly. Thanks for the help and the continued content.
Bottom line, don't remove all 4 cradle bolts at the same time. You want at least one in there to keep the cradle in line. If you can get it done with only removing one side at a time that's best but I had to loosen some on both sides to get it low enough.
That’s what I thought you were getting at as you alluded to it later in the video, but I wanted to make sure. It’s always best to ask rather than assume and make mistakes. Keep up the solid content!
Good stuff Speedy👍👍
Thanks 👍
Question? Can't you just cut the head off that bolt you can't slide out
and put the new bolt in the other direction that way you don't need to drop the cradle..
You can, but I'm not cutting on the car.
@@SpeedysGarage not the car but cut the head of the bolt off so you can slide it out without dropping the cradle.
Put the new bolt in backwards from how the factory slid it in.
Yes, a sawzall with blade upside down you may need to move the rear caliper but its easy and you get new bolts anyway. No cutting on the car itself.
I'm subscribed!! I enjoy your videos. Dealing with wheel hop ...
Love the channel Speedy! Great video and great choice going with AAD parts.
You commented about the shortened End Links and how close they are to the Upper Control Arms under extreme load. Why not just go with Adjustable End Links and be able to set that space to your liking? Anyway, just an idea.
Keep up the great work.
If I have issues I'll check in to them. BWoody links are reported to work as well, but so far so good on mine.
@@SpeedysGarage I have the BMR Adjustable end links (bought them to run 17's as well) and they have worked great. They are well made and strong.
Anyway, looking forward to the Alignment video. I am planning on installing the same kit soon and really appreciate the in depth videos.
If you don't want to drop the cradle for the upper trailing arm inboard bolt that's against the body all you have to do is loosen the bolt and then cut the head off. Installation of a new bolt the the nut against the body. In your vid you mentioned cutting the frame that's not necessary. To do the toe arms and the sway bar or any of the cradle bushings you will need to drop it to change those items.
True but I'm not up for cutting things off the car, bolts or otherwise. Dropping the cradle was super easy and took about 30 mins.
@@SpeedysGarage Did I hear you say leave off the trailing arms and install them last.
Shoot, forgot to add, Thanks for a Typical Awesome detailed video!😉👍
Thank you. Very good video.
Great detail and tips in your video as always.
I gotta tell ya though, please rethink not putting a permanent 2-post lift in your awesome shop. Watching you bend down and work on the suspension was killing my back. My shop is 16''8"wide by 28'8"long (interior dimension) as the 3rd bay of my garage. I added a 12' tall, 10K pound DP10A Forward lift and my cars get a lot more attention underneath simply because it's easy to put them in the air and inspect them. Little stuff get's attention that never would. And my back and knees don't hurt. Yeah, I'm older than you.
Just some friendly advice: Stop worrying about how those posts will be in the way - your garage is huge and you won't mind a slight detour around them but your baby will get much better care once you have a lift.
I had full intent to put one in when I built the shop. Just got spoiled by the space. Maybe one of these days, luckily the Hellcat has been super reliable so I've really only needed a lift twice now in the 4 years I've owned it.
Very interesting video. I run short links on my Scat Pack. I took the stock links, shortened them 1 inch and re installed. I've done several sets and they work great. Curious to see what your 60 ft times are now.
Just got my kit in. One of the things I thoroughly don't enjoy is dropping that cradle. Just never a fun experience doing it solo in the garage.
Great video but your comment about an extension changing torque is incorrect. If it is a straight extension there is no change in torque. If you use a crows foot or are torquing a bolt that is offset from the drive rotation you need to make adjustments but a straight extension does not effect rotational torque.
Good Video! Thanks!
Any Drag race results yet? I just installed the control arms and the BMR Lockout kit on my friends Hellcat Redeye. We are waiting on a track date and his cage to get installed. So far the car drives noticeably different in a good way. Anxious to hear your track updates while we wait.
Almost pulled the trigger on them , curious to see the difference in performance. Have you looked into a set of Demon Killer springs from Carlyle Racing?
I have, but I don't want to change the ride on the street very much.
Swap the install direction of the 2 problem bolts.
Pain in the a** factor ✅
So you gained a couple of lbs overall, 'can't wait to see some rotational mass reduction happen...
;)
Me too :)
Hello. Is suspension good for for drag , possibly making car higher for bigger tires ?
Have you added the
Killer Chiller to your ride?
If so what do you think?
No, I don't think they're necessary.
You need Max Jax brother
I know this is a year old, but did you notice any contact on the rear sway bar? How would you rate this mod? Was it worth it?
Hi Speedy...Great vid and very helpful tips. That nice shop makes it look a lot easier than it is and I consider 5-hours as pretty fast. This is definitely a 2-person job, both with a high level of skill. Will be very interested in how the thrust angle alignment turns out. Did you consider replacing the bushings at the cradle mounts? If I had your money I'd burn mine (LOL) but I would definitely put in a lift. Just yesterday I got the new 2020 Challenger Service Information from Tech Authority (MOPAR.COM). Following the linked information under the Rear Suspension Spring Installation will eventually lead to a Torque Spec Table in Chapter 13 Frame and Bumpers. The rear suspension crossmember (cradle) to body bolt torque value is 185 N-M 136 Ft Lbs. Hope that helps. BE SAFE
Thanks for that, I'll set them to 136 ft/lbs. I'm very happy with the ride of the Hellcat and I only want to do enough to get the 60' optimized, so I've avoided doing cradle mounts. I'm hoping this suspension will get me what I'm looking for.
@@SpeedysGarage I, like the others, will be waiting for your follow-up and how much shim you put in for the track. More important will be how you determined how much to put in. I know you already know this from your past experience but thought I would tell you anyway. From what you described as to how you did the work, you are in good agreement with what the manual says with one difference being (and you may have done this and I just didn't hear it) but the manual says to put the car on the alignment lift (which I interpret as load the suspension to ride height) and then tighten the suspension arm(s) bolts to final torque spec (they do say to raise the car just enough to access the bolt). From my past experience this is a standard requirement which allows the bushings to be unloaded in torsion i.e. no preload at ride height and they will last longer. AAD should have had some instructions. Good luck in next seasons racing. BE SAFE
You actually can't get to a lot of the bolts with the cradle even in the car LOL, so we had to tighten them where we could reach them, some with the cradle lowered. The AAD parts use derlin or spherflex (sp?) bushings so hopefully they're good to go with that method.
@@SpeedysGarage Yea...that's why they say to raise the car enough to get to the bolts. After I sent the last reply I went to the AAD web and looked at their instructions for the rear lower trailing arm and sure enough they did not say anything about setting the car down before final torque. I sent them an email asking about that and the lubrication instruction. Hope they get back with me. Thanks for your feedback, I now have a better idea of what I'm up against and what's OK and not OK.
Speedy...Sorry don't know how to edit my last reply...I just read more of the AAD component instructions and understand what you said about not being able to get to the bolts with the cradle attached to the car! I wonder how or if anyone takes their recommendation to recheck the torque 1-2 weeks after installation...take the cradle out again??? Better buy the multiple alignment package which I never have done before...have a good evening and thanks, this was really helpful.
Do you have a street set up and if so what tabs were used?
I liked the track setting so much I just left it in there.
Did you install the front A-Arms from AAD?
Just the rear.
Do you have a link to the jack stand supports for the frame?
They're the ZL1 jack pads.
@@SpeedysGarage Thanks
Did you fix the air leaks in your shop?
Not yet stay tuned. Will be a good over the winter little project.
So getting ready to install mine and was curious did you add a little to you end links I know you said it was close but I figured by now you drove it a couple times and maybe decided to lengthen them for a little more Clarence?
Check back for Friday's content :)
For a guy that is so annal about this car why do you not have a lift .
Maybe one of these days.
