More psi would make the ride more squirrely. I am only running 28-30 psi and have a full foot print, which is what you want. If you want to adjust caster it is recommended to front lower control arms, as a lot of adjustable upper arms will not adjust short enough to set the caster. If you need to line up your rear drive shaft and pinion then rear uppers is what you want at a minimum. Optimally you would want all eight adjustable control arms, but front lowers and rear uppers will suffice.

 

JUST INSTALLED JKS ADJUSTIBLE FRONT LOWERS SET LENGTH TO 22 3/4 INCHES RIDES WAY BETTER. WANT TO EXPERIMENT A LITTLE TO FIND THE BEST POSSIBLE RIDE. THEN WILL TAKE TO ALIGMENT SHOP TO RECORD AND CHECH EVERY THING. THANKS FOR HELP. INSTALL WAS FAST AND EASY.
