3 inch lift ride quality on 37’s

How big of a change were the geo brackets? I've got some bumpsteer and it crashes over broken pavement..

Those coil springs look really thick. Compare them to a stock spring and you'll see thw difference. Cheap lifts often do that. No money is spent on R&D for a decent spring rate, so they just wind a really thick coil to achieve lift height. This results is a terribly stiff ride. Based on your description and the red paint, I would guess that's likely a Skyjacker lift, which are known to ride like an old chuck wagon with zero suspension. Also, as noted elsewhere, check the tire pressure. Some people who just have no clue will fill tires to the "max psi" written on thw sidewall, or will put 40 or more psi regardless. A tire with an already stuff sidewall, with touch air is going to rude terribly. Finally, if the kit didn't include new lower control arms or geometry orienting brackets, your caster is going to be way out whack, causing flightiness and tracking issues. Steering stabilizers only work to control the tires after hitting a large bump. Also, those tires are really not that aggressive at all, and should not be causing any issues.

One of the best investments I have made. If I had to choose between geo brackets or adjustable LCA’s, I’d go geo brackets.

What do you mean crashes over broken pavement?

what’s a gel bracket?

Springs too soft, not enough uptravel, castor isn't dialed in. Progressive bumpstops might help too.

what’s a gel bracket?

A geometry correction bracket. It effectively restores the proper angle to the lower control arms. As you lift the Jeep and don't add adjustable control arms the axle is pushed down by the lift and it causes the LCA to sit an angle. If you look at a stock rig the LCA's sit about parallel to the deck. I'm sure you may still need longer or adjustable LCA's. I added my gel brackets to already installed adjustable LCA's. However, do some reading, they are pretty universally appreciated as a worthwhile investment.

Steering stabilizer won't do anything for stiff suspension, and I would definitely try to identify the lift kit that was used. Perhaps there are some part/production numbers stamped into the springs that you could cross reference? Maybe ask your sales person to contact Rocky Ridge and find out?

When I went to 37s and a 3 1/2" lift from the OE JTR Fox set up, my ride did seem to improve *a little*, but not enough to write home about.

What is your point of reference in terms of stiffness with the JT? Did you drive another one without this setup and it felt more "comfortable"? Not sure if this is your first, but in my experience, first time owners of straight axle vehicles typically need time to get used to it. They just feel more rigid. The other 3 vehicles in our driveway (66 GMC pickup, 07 Mustang, and 2021 Bronco 2 door) all make my JTR feel like it has cinder blocks for suspension, but it has felt the same way pre and post lift. My JKU was the same way. Just my $.02.

I don’t understand this. My 21 JTRD rides plush. It soaks up humps, road irregularities…up to the point the front bottoms out (different topic) and is a pleasure to drive.

E

E rated tires are 10 ply intended for 3/4 and 1 ton trucks. The load rating is way above anything you’re rated for. The tire pressure on the sidewalk will read 80psi. I’m interested to hear how much air you’re running.

No suspension compliance on small short duration hits.. We have some nasty frost heaves, typically extremely "sharp" bumps, 2-3" tall.. The jeep feels like it hits these and transfers all of the force directly into the frame through the LCAs. On bigger whoop types bumps its pretty good, just with a little bumpsteer.

Sounds like geo brackets may help me..

I bought these - https://www.aev-conversions.com/product/jl-geometry-correction-brackets/

I'm sure there are others someone might recommend.
