I put a set of Nitto 295's on my 06 F350 Dually and then wanted to get a height also. The truck was level from the factory and I put a 2.5 in leveling kit on the front which really gave me the fender clearance I was looking for. But now I would like to raise the rear about 2 in. and I don't want to add blocks. Does anyone know what the height of an F-450 bump stops are and could I use these to replace mine and get the added hieght I'm looking for.
