Protecting your towing equipment doesn’t just mean investing in a high-performance hitch — it also means securing it properly. The CURT Rebellion™ XD Tongue Lock is specifically designed to provide added security for your Rebellion XD adjustable ball mount system. Instead of relying on a standard clip, this lock secures the tongue to the vertical shank, deterring theft and preventing tampering with your setup.

Crafted from durable cast aluminum, this tongue lock is built to withstand tough weather conditions and resist corrosion for long-lasting performance. The design fits seamlessly with all CURT Rebellion XD accessories, locking directly over the vertical-shank pins to keep your attachment firmly in place. Operation is quick and easy thanks to the 1/4-turn activation system, and the lock comes with two keys for added convenience.

Whether you use your Rebellion XD to tow a camper, boat, or utility trailer, adding the tongue lock gives you extra peace of mind. It’s a simple upgrade that delivers big on security, ensuring your cushion hitch system stays safe and secure when it matters most.

  • Quick 1/4-Turn Activation – Simple, fast locking mechanism for everyday convenience.
  • Perfect Fit – Designed for seamless compatibility with all CURT Rebellion XD accessories.

Additional Benefits

Terms to Know

  • Tongue Lock: A device that secures the tongue portion of a ball mount or accessory to prevent unauthorized removal.
  • Vertical Shank: The upright portion of the Rebellion XD where the adjustable platform and accessories attach.
  • Cushion Hitch Technology: An advanced system built into the Rebellion XD that minimizes jerking, rattling, and jarring while towing.
  • Pin Clip: A basic fastener used in hitch systems; while effective, it offers less security than a dedicated lock.

The CURT Rebellion XD Tongue Lock is the perfect complement to your Rebellion XD adjustable ball mount. With its rugged cast aluminum construction, quick-turn locking system, and tailored design, it ensures your towing setup stays safe and secure. For anyone serious about protecting their investment in the Rebellion XD system, this tongue lock is an essential accessory.
