It Just doesnt look tall enough I have 35s on her right now. Just doesn't quite look right is all.You cannot run a 3" Body lift on a 2500HD. Reason being, as it looks terrible, shows basically the entire frame rail. You have a 2500HD, with a 6" lift. What wheel/tire setup you trying to run? Tons of people have 35-37" tires with x 9 & x 10 wheels with just lift.
