depends on the shock length. if you got the standard ome shocks the front operates on stock stops 13.5/22.5".
the rear @13.5/22.5 will use 1" extensions. If you also installed a track bar relocation bracket that raised the track bar 2-2.5", that requires a 2" rear bump stop extension because it will hit the tub and chop the fuel pump harness in half if it's hanging out enough, unless you also have a 1" body lift.
If you have the long travel shocks, front 15.5/26.5", 2" minimum bump stop extensions and the springs will unseat almost 3". the rear 14/24" will require 2" bump stop extension in stock mounts. if you have the pinon rotated and use a shock shifter/extension, the bump stop grows to 3".
32" tires generally need a 1" bump stop extension to keep the tire from remodeling the fender.
I’m running the Bilstein 5100 shocks with the OME HD springs. The fronts are 13.06”/21.08” and the rears are 12.81”/20.08”. I’m running a rear track bar relocation bracket and a 1/2” Rokmen body lift.
