I'm thinking of dropping my current leveling kit and picking up a set up the Bilstein 5100's. So my question is, is that all I need to level it? Or do I need springs or anything else?
they offer no additional lift. they can be used in a truck that has up to a 1.5 inch lift because of the installation of a block, extended shackle, add a leaf, or new spring pack, but they do not have a ride height feature like the fronts.I used a TGC 1.5 spacer in the rear. It is similar to adding blocks to trucks with leaf springs. I think you can get some lift with rear bilsteins though too.
