...As for the springs, I've never really looked into it, buy why do people choose to run XJ springs in YJs? Is it only in the rear?
You don't really notice it on XJs but the center pin (where the axle is located) is actualy offset. I think it's offset 3" to the front. On the YJs and CJ's you run the XJ sping backwards (with the offset to the rear). This instantly extends your wheelbase roughly 4 to 5" cuz its also a longer spring. I've gone further by mounting the shackle hanger on the back end of the bumper. Haven't checked but i'm probably running about 7" stretched in the rear.
Longer wheelbased rigs climb & descend obstacles better. More importantly for me is that with the stretch, comp-cut corners and tube fenders, i can run a bigger tire with zero lift. The fronts are STOCK YJs and the rears are STOCK XJs. Otherwise i'd need a ladder to get into a normal jeep on 38s.
