This replacement clip for the Rebellion™ XD ball mount is designed to keep the hitch pins securely mounted in place on the vertical shank. It features a unique, single-clip design, allowing one clip to secure both pins. Installing over both pins also provides a degree of vibration resistance. The Rebellion XD adjustable ball mount is a leap forward in cushion hitch technology. It provides more control, confidence and a more comfortable ride, all while protecting your towing system from jerking, jarring and rattling. The Rebellion XD is not included in this package and must be purchased separately.
