Rear Installation

2. Remove the wheels, rear brake line brackets, and factory shock absorbers.
3. Remove factory u-bolts and blocks. Lower the axle to install the new 3-inch blocks.
4. Install the new u-bolts and tighten in a crossing pattern.
5. Replace bump stops with the supplied extenders.
6. Install new shock absorbers and extended brake line brackets.
