To use this rear bumper bracket, first pick the side you need. Make sure the frame rail is 30mm. Drill a hole in the frame to bolt the upright part. Slide the bracket inside the rear frame rail; no extra hardware is needed for the inside part. When using, be careful while drilling the hole to avoid any mistakes. For maintenance, keep it clean. If the black oxide finish shows signs of wear, you can touch it up to keep it looking good and prevent rust.
