ok, so im getting ready to finally lower my '01, and since this is the bastard year, there is barely anything available. I have found a 3" drop coil from western chassis, and i plan on flipping the rear hanger, and belltech drop shocks. I am expecting a 3"-4" drop, but i have a few questions. with a 4" drop out back, hanger flip and shackles, is it necessary to shim the axle? with 3" in front, which bump stops do i need? I'm sure i'll think of something else, but so far thats what ive got. Thanks in advance.
