AEV 2.5" vs MC 2.5" Gamechanger

[Fast-n-Furious]

I don't think that had much, if any, influence. I believe it was more the additional unsprung weight and different wheel offset. It wasn't that bad, but the SteerSmarts made the Jeep drive like a dream and better than my 392 when stock. Like you, I prefer the D load rating. The standard AEV springs have worked well and I did upgrade to the 8100 AEV/Bilsteins and it is the perfect combination for me. If I was into overlanding and had the RTT and other items that added a ton of weight, I would have upgraded the springs, but I prefer a hotel these days.

Did the steer smarts tie rod and drag link make that much of an improvement? I installed their track bar bracket (just bracket, no sector shaft brace) and I couldn’t tell the difference other than reinforcement.

Yes, it really tightened up the steering after installing the 38s.

@Warped Did you ever go off-roading with the 38’s? Any rubbing?

Waiting for Black Friday to pick this up for hopefully some discounts coming. idk which springs to go with standard of high capacity. I don’t have it set up for overlanding but is the progressive spring better for the 392?

Tagging in on this. I want to run the AEV lift and 38's. Currently on 37's with -38 kmc tanks...

I did go off-road in Ky and did not notice any rubbing before the front driveshaft and upper control arms were destroyed. I had stock upper control arms to get me back home from KY and is now getting more upgrades from factory parts.

If you aren't rubbing on factory fenders. you are using too much bump.

Sorry to hear that! It just asked for more upgrades and forced your hand, oh good old jeeps

For those with the AEV kit with with remote reservoirs, how much room do you have from tire to front remote reservoirs at full turn?

I have about less than a fingers width or room. Wonder if this will be an issue off-roading with its location. They are moved up, I might be able to get maybe 1/4 inch more upward.

I’m on stock XR wheels with 37x12.5.

Do you know what AEV recommends for wheel backspace ? I know most lift companies have recommended minimum backspace requirements for clearance issues.

Idk I can ask. I know the XR wheels have less backspacing and lower offset, so it sticks further out than the AEV wheels that come with the build. So my assumption is if their wheel is move tucked than my XR, I should have no issues based on the location of the remote reservoir.

I like the AEV lift , so I was curious. Thanks

So I just installed the AEV XP kit on my jeep 392. I did the standard springs not the high capacity bc I dont carry a lot of weight all the time.

What I don’t like has been the body roll feel, I actually got little nauseous on a back road, first time in the driver seat to get that. Ride quality is fantastic and smooth But I have to fix this body roll feeling for me and the family. I am on 37x12.5r17 cooper rugged trek tires and on stock XR wheels.

I called AEV they recommended 2 things to help but wanted to ask here and get more insights from ones who have gone with this kit or similar.

1. Add a heavy duty sway bar in the rear bc the 392 can’t use their rear geometry brackets in the kit they provide.
2. Adjust the control arm bracket-move more toward the rear and add more caster.

My jeep does pull to the right after all this, here is my alignment sheet. I do have the Mopar LCA & AEV steering stabilizer on as well. I choose AEV based on feedback on how well and planted it drives but right now I haven’t experienced that benefit fully. What is everyone’s thoughts?

I have the AEV set-up but with the high capacity springs and am very pleased with it. No bounciness, vibrations, pulling at all.

Here's what I have on my 2024 392:
- AEV 3" DualSport XP with High Capacity springs. My Jeep is quite heavy (armor, AAL platform and drawers, fridge, etc)
- Replaced the original control arms with Part Number: 68322798AA. These arms are just a tad (maybe 1/4") longer than the 392 OEM ones.
- Full SteerSmart Yeti HD front set-up, including their Griffin Attenuator, drag link, tie rod, sector shaft brace and bracket - this improved the steering tremendously, including no offline pulling whatsoever
- 37" MT Baha Boss A/T tires on original 392 rims.

Attached are my measurements.

Ok I will have to look at the other parts you have but I have the Mopar control arms.

Do you have any extra body roll? After the install I haven’t felt more body roll that I am not happy with.

No extra body roll, but it is a high centered Jeep on 37"s, so there is roll for sure especially in sharp corners, same like in any SUVs. None on normal driving though.

It seems that the "normal" springs might be too soft for the weight of the 392, with the shocks not being able to compensate for the bouncing induced by this softness. Just my 2 cents.

Also, looking at the alignment numbers, my caster seems to be a tad larger than what you have. You might doublecheck if the strange washer that AEV uses to push the lower arms is properly set.

Yeah good point on the springs. I talked to AEV they said the strings should be good for what I have. They said it wouldn’t effect body roll to much if I went to stiffer springs which I don’t agree.

That weird spacer is what they said to to add more caster. So will have my shop look at that and choose a new shop next time.

They recommend a HD rear sway bar like hellwig since the geometry brackets are not used on 392. Would this greatly impact off-road or little? I’m in NC and we have Uwharrie which I have done on stock 392 XR no issues. So idk with this lift kit and say doing the HD rear sway back I’ll have issues. Any experience?

For the rear, this is from the AEV instructions:

On the 2024 392 there is already a (thinner) spacer there added from factory (the 2024 had 35" as OEM). Per AEV the OEM one was sufficient as long as the sway bar was reversed.

The front LCAs needed to be flipped left side to right side as well. There were few little caveats every here and there that a shop that didn't read the instructions might've missed. Perhaps an install audit would help?

Yeah I agree! Frustrating to pay a shop and have to double check their work or go elsewhere bc they can’t take the time to read instructions. Good quality shop to idk
