I am guessing my rear springs are worn out? And that whats causing it to sag. My question is what is needesd to fix this problem? New springs if so which kind? What about a set of AirLift bags? I will be gettin 18x10's in the rear with 335's so i don't think lowering the rear is a good thing for me. I do know that I might lower the front depending on fender gap with the new wheels.
