Need to buy new tires for my 97 c2500 (tow/dd) soon. Just picked up a set of H2 rims for it and want to throw some just SLIGHTLY larger tires on it. I just want the thing to look like a truck and not some wimpy sad little thing(as it does now). So does anyone have experience running those polyurethane coil spring spacers on a 2wd? My worries are, if I put the 2.5" ones on, there won't be enough adjustment in the stock alignment setup to compensate, and that they will just degrade and break up from use under at truck that actually moving crap. I just want to bring the front up to level and maybe just a little bit past where the rear is now and throw some airbag overloads on the rear.
