Out back, the truck gets a height increase via 5-inch lift blocks. These blocks have built-in bumpstops. Longer U-bolts, a brake line relocation bracket, and E-brake relocation bracket are also included. Our upgraded gas shocks bolted right on, but if installing the BDS 5500 Series shocks the passenger-side bumpstop pad will need to be trimmed due to the larger diameter of the shock body. Instructions for the trimming are included.
