I got a 01 Gmc sierra with 4wd and it's already lowered 2/4, but thats not quite low enough for me. Right now the front torsion bars are turned down and shackles in the rear. I want my top of my tire to sit flush with the fender opening. My summer tires are 305/45/20 all the way around. I've seen some trucks around town that have the stance I want and I think it is 4/6 drop but I was just seeing if anyone had ideas on how to do that with a 4wd truck.
