All lift coils will vary with various accessories. Common problems with squatting in the rear are typically found with X-Factor kits installed with improper control arm lengths. The rear pinion angle needs to be pointed 2-degrees below the output on the transfer case. If not, it will cause the coils to lose effective rate and squat. Covered in the last page of our installation instructions http://www.pureperformancegroupinc.c...K_MA_02-16.pdf

If you're planning on running heavier accessories on the rear and not adding a winch (light front) we are suggesting using the Expedition or Overland systems. Those rear coils are more suitable for vehicles with increased weight biased towards the rear of the vehicle.

Installed my RK 2.5 Stock Mod a week ago paired with fox 2.0's. Can't describe how happy I am with the kit. I was oblivious to how bad my old suspension had become. Running some pretty worn down 285's now. Gonna go 315 soon.

So a 2dr with no winch and a heavy rear would use the 2 dr 2.5" front coils with the 4dr 2.5" rear aka 2 dr 3.5" rear for a level stance correct?

Correct. I was given the same option for my basically stock 2dr......steel front bumper and aluminum rear, with a slick all terrain spare tire, aluminum wheels all around.

I had to politely decline the offer for now, though I may have to take them up on it in the future.

So you're having sagging issues too? Your rear is pretty standard weight for jeeps.

Mine sits (visually) 3/4" lower in the rear. Putting a level on the rubi rail and the door reveals that it's level there. I'm doing a 3/4" spacer in the rear to compensate.
