Procomp 4inch stage II lift sag fix
Looking from some help figuring out how to fix a problem I have. With the edition off a winch and all the bumpers and stuff I've added to my jeep has caused it to sag pretty bad. So bad that my front axle is off by about an 1inch to the passenger side. I have adjusted the trackbar that came with the kit but it's still off by an inch. Rear off by 3/4 of an inch. Thinking about adding some spacers all around to bring it back up. But have no idea how much to add with the short arms. Anyone have experience with the issue and how did you fix it. Thanks

When you say your axles are off, are you talking about the height or side to side? If your talking about height, why would you adjust the track bar? That does not adjust height, only centers your axle under the vehicle. For height lost due to heavy bumper and winch, add coil spacers. I added 1" front and 2" rear on mine and it rides great. Just figure out how much you want to go up and order the spacer size you need to achieve the height you want.

Renpia - it's off side to side, not centered that's why I adjusted trackbar. Do you have the procomp 4 inch lift and added the spacers on top of it?

If your diff is off side to side, you have to adjust your trackbar. It appears, by your explaination, that there is so much added weight that it has affected the trackbar length. I can see how it may affect the side-to-side shift as the more it has sunk, the more the trackbar would push it out.
FYI, when a lift is installed, the front diff gets pushed out toward the drivers side and the rear to the passenger.
It doesn't matter if it's a 2 1/2" or 4", the only change is how much it has shifted
Here's an article describing what happens when a lift is installed. And how to correct it with your adjustible trackbar

You also mention a sag issue. This is a completely different problem. Most of the time it is caused by heavy accessories. Corrections include what renpia suggested, or progressive springs, or even adjustible coil spacers (ACOS). These corrections will get back the height lost
Hopefully this will make sense.

Yes I have a 4" Procomp and added spacers after putting heavy bumpers, winch and big spare tire but I didn't lose more than 1".
