I I have a 95 k3500 rclb that I put a 3" body lift on and 285 tires. I want to crank the bars and block the rear for another 2" of lift. Will I be able for fit a set of 37" tires or will 35" be my max? The truck sat pretty high when stock compared to and 1/2 ton so I figured I may be able to squeeze a 37 onto it. Btw its a srw, 454 5 speed with 4.10 gears I believe. It turns around 2k rpm at 55 MPH so I'm hoping the big tires will help lower my highway rpm down some.
