I had a Trailmaster 3" body lift installed. Included were 10 bolts and blocks, and no bumper relocation brackets. As a result, I had to have custom brackets made to move the bumpers up 3" to compensate for the lift. The truck leans a bit more with the body lift, but nothing major...still the same smooth ride. The fan shroud and tranny linkage had to be adjusted, but the gas filler neck was fine.
