I have a 2003 2500 4x4 and am planning on getting a leveling kit to run 35s on my stock rims in the spring. I have never lifted or leveled any of my trucks, how important is it to re-center the axle after doing the lift? What happens if you don't? Whats the best way to do it I'm a college student on a tight budget. Is their any kits that include everything, also I was interested in the Kore leveling kit but does this also require re-centering the axle?
