The CURT RockerBall™ cushion hitch provides improved comfort and enhanced control while towing, featuring our unique ShockDrop™ technology. An integrated cushion isolator allows the hitch ball to turn the standard ball mount into a cushion hitch with anti-rattle capabilities.

The RockerBall™ ball mount kit is a shock-absorbing hitch accessory that dynamically reduces jerking and jarring while towing. As your trailer passes over bumps and potholes, it produces all kinds of vibrations, jolting, chucking and noise. With a traditional metal-on-metal connection, these annoyances are directly transferred to your tow vehicle, making your ride noisy, uncomfortable and taking a toll on your towing system.

The RockerBall™ completely changes your towing experience by absorbing the erratic movement and rattling of your trailer at the coupling point. This provides a smoother ride and increased control over the vehicle and trailer. It also reduces the amount stress placed on your vehicle, receiver hitch, brakes and suspension system.

The RockerBall™ is also extremely low maintenance compared to other torsion hitch and cushion hitch options. It has no airbags or bearings to service. Simply apply grease to the integrated zerk fitting as needed for continuous lubrication and smooth operation.

This RockerBall™ hitch kit comes with a standard ball mount with a 5" drop and standard 2" shank to fit most class 3, class 4 and class 5 receiver hitches. It also includes an anti-rattle shim kit for maximum vibration resistance.

The CURT RockerBall™ hitch ball is constructed from forged steel for exceptional strength. The base and ball mount are covered in a durable powder coat finish, and the ball itself has a chrome plating for long-lasting weather resistance.
