Rear squat before & after lift

[Operative73]

I swear my Jeep(2020 JL2door sport s) has had a rear squat. It seems level to me without the hard top and rear seat(softop installed). So:

Before lift seemed to squat with:
Steel bumpers front(70#), winch(63#) and back bumper(aprox 100#), aftermarket wheel/tire(combined approx. 85#) rear seat in, hard top.

After Terraflex 2.5 lift shocks(9550 VSS)/springs seemed to squat still:
Steel bumpers front(70#), winch(63#) and back bumper(aprox 100#), aftermarket wheel/tire(combined approx. 85#) rear seat in, hard top.

But it seems not to squat when I remove the back seat and have the softop on. Other than that there were no changes on how it was equipped that would add weight.

Now I know removing weight will cause it to rise a bit but I wouldn't think the weights were talking would be at all noticeable, which I think it is. The apparent(imagined??) squat being due to shocks and/or springs should have been corrected when the lift was installed, assuming if it did squat due to OEM/worn hardware. Same tires, same pressure.

Questions:
1. If parked on a surface checked to be level, would the frame be a good place to check for level or is there a better location? ( the computer bult in tilt-o-meter display on pitch?)
2. If there was a rear squat both before and after the lift when fitted out the same and all shocks/spring were replaced, how can that squat be corrected/jeep leveled out? can you add a short 1.5/2" spacer just on the rear after a suspension lift?
3. Or am I imaging that squat or being fooled by some fender optical illusion or something?

Yup, that is a Carolina squat you have going there. A couple of potential fixes come to mind.
1. Lose the 100 lb rear bumper and go with something smaller, trimmer, and half the weight that is just as strong.
2. Go up a tire size. Your Jeep looks like it skipped leg day at the gym. Larger tires will decrease the fender gap and make the squat less noticeable.
3. Add a 3/4" spacer to the rear springs or swap rear springs for the next higher lift height. You may then need longer rear shocks or shock extensions. (then see #2 above).

Good luck with it.

Kept seeing a squat as well. Over the winter, I put in a 3/4in spacer for the rear springs.

Those sized tires were from before the lift. Plan on going bigger when new tires are due.

Those sized tires were from before the lift. Plan on going bigger when new tires are due. Adding a 3/4" spacer, I know you can add spacers to factory suspension, can I still add them after the Terraflex?(I don't see why not but there's a lot I don't know.)

Update, just got off the phone with Terraflex. The shocks on the 2.5" lift(what I have) are the same part # as their 3.5" lift, so won't need shocks and it seems like a 3/4" spacer may do it but the shocks could go 1" if needed.

I will load the Jeep with the seat/hardtop to get my 'heavy' stance. I'm still left with, what would anyone recommend as the best way to determine what's level? frame to ground, compare front and back? is there a better method?

Thanks

Had same problem with my 2 door . Added 3.5”rock krawler springs to the rear. Fixed the issue. Had the mopar 2” lift, and it looked just like yours

So after your 2" mopar lift you added 3.5 springs, 1.5" taller spring over lift spring?

My 21 JLUR 4xe had a squat in factory form and with lift. Had to put 3/4" puck on the rears and now it site level on Teraflex 2.5 ST2. Squat is pretty common issue.

It's somewhat aesthetic, but if you want to get scientific, check the ground for level, then level at the flat portion of the frame between the wheels. You have basically a 8' wheel base. If you use a 4' level, on the frame, pull the front of the level down until it's center bubble and measure the distance you pulled it down. Double that will be the delta at the axle.

Depending on how tight you are on cost, you can move to 3.5" springs in rear instead of spacers, but the spacers will work for you.

Remember the fenders start at different heights, so they aren't a good place to measure from.

The lift dropped after 2 years, so it just brought it back to level, I think there was a slight droop to start, but with my gear in the back, it’s a perfect now

My technique was to eyeball--since that is what indicated my Jeep had a squat. I put a scissor jack under the hitch and raised until the whole Jeep stance looked proper. I measured at the fender flair extensions inline with the axle center to the floor.

Turns out, I now have the same height above the tire to the fender flare extensions for the front and rear.

I swear my Jeep(2020 JL2door sport s) has had a rear squat. It seems level to me without the hard top and rear seat(softop installed). So:

Before lift seemed to squat with:
Steel bumpers front(70#), winch(63#) and back bumper(aprox 100#), aftermarket wheel/tire(combined approx. 85#) rear seat in, hard top.

After Terraflex 2.5 lift shocks(9550 VSS)/springs seemed to squat still:
Steel bumpers front(70#), winch(63#) and back bumper(aprox 100#), aftermarket wheel/tire(combined approx. 85#) rear seat in, hard top.

But it seems not to squat when I remove the back seat and have the softop on. Other than that there were no changes on how it was equipped that would add weight.

Now I know removing weight will cause it to rise a bit but I wouldn't think the weights were talking would be at all noticeable, which I think it is. The apparent(imagined??) squat being due to shocks and/or springs should have been corrected when the lift was installed, assuming if it did squat due to OEM/worn hardware. Same tires, same pressure.

Questions:
1. If parked on a surface checked to be level, would the frame be a good place to check for level or is there a better location? ( the computer bult in tilt-o-meter display on pitch?)
2. If there was a rear squat both before and after the lift when fitted out the same and all shocks/spring were replaced, how can that squat be corrected/jeep leveled out? can you add a short 1.5/2" spacer just on the rear after a suspension lift?
3. Or am I imaging that squat or being fooled by some fender optical illusion or something?

I had the same issue back in the day with my jeep. After too mods it seem my rear end on my jeep was sagging after a 4.5 lift. I fixed that with a terraflex spacer kit to remove the sag. I think if you get the 1” spacer kit that might solve your problem.

might be a while til I'm back in a hard top and rear seat, but this is getting fixed because
