I have a 1999 crew cab short bed 4x4 classic style truck. It's a 2500 8600 gvrw with the 454 and 4l80e. I don't know where I want to go with it though, I've been going through 2 options. 1, get some western chassis lowering torsion keys, and a bell tech rear 4 inch drop to achieve a 2/4 drop. Then run some 295/45r18 front and rear and have it be a 4x4 street truck. My other option I've been considering is get the 4" rcd knuckle lift and and run some 20x14s with either 33's or 35's, possibly even some 36x15.50 I found. What do you guys think?
