Detailed Installation Instructions

1. Use transparent tape to cover the mounting post hole on the top of each mounting bracket (when the pilot hole is
drilled through the bed, the tape will be pierced by the small drill; it should be positioned in the center of the 1”
mounting post hole).
2. Install the rear bracket nut plates {Q} by clipping them onto the frame as seen below.
3. Align the rear driver side mounting bracket {B} flush to the frame using the provided nut plates to attach it.
4. Fasten the mounting bracket flush to the frame (some mounting brackets may have a slight warp due to the metal
characteristics during the welding process) by using either a clamp or by inserting a fastener through the
mounting bracket in the existing frame hole(s). Do not overtighten—you will be removing the brackets in later

WARNING: Prior to drilling any holes, be sure to check the inside of the frame to guard against drilling into the
fuel tank, wiring, brake lines or fuel module
