This kit includes a rear bumper that changes the point of the tilt of the bed so you can still tilt it for service or use the box as it was designed for. The kit also includes the right and left rear sidebars and the bar across the top at the back. The rear bar has foam padding and black canvas cover with Velcro to hold it in place. The bumper bolts to the existing rear suspension holes. Only requires drilling to install the bed tilt brackets. Clamp collars used to clamp to the bars are patented by Rockhard 4x4 Parts and have been used in over 3000 jeep sport cages. There have been over 100 rollovers without failure. No welding to install. The Rear Section Sport Cage can be ordered uncoated (bare metal), Black Powder Coated, Silver Powder Coated, or Black Crinkle Powder Coated.
