With the reliable strength of The 2" Heavy-Duty Original Patented Roll Back Tie-Down System with Chain Ends from B/A Products Co., you can begin to start securing your vehicle with much more confidence. Offering you a solid kit that can cover you from all angles, the straps are designed to keep the wheel from moving forward, backward, or side to side during transit. By securing the vehicle by its tires, you are letting it ride on its own suspension, which reduces the chance for damage. This kit is designed for carriers with four tie-down points on the bed.
