CURT 2-5/16" RockerBall Cushion Hitch Trailer Ball - 12,000 lbs

The RockerBall Cushion Hitch Trailer Ball by CURT is specifically designed for marine enthusiasts seeking reliable and smooth towing performance for their boat trailers. With a robust 12,000 lbs capacity and innovative ShockDrop™ technology, this hitch ball ensures enhanced control and comfort, making every towing experience effortless and stable.

Superior Towing Control and Comfort

The CURT RockerBall™ trailer ball upgrades your standard boat trailer setup into a cushion hitch system. This integration effectively isolates vibrations and reduces noise, providing a quieter and more stable ride across various marine and road conditions. Whether navigating rocky docks or bumpy roads, the RockerBall™ ensures your boat is securely towed with minimal disturbances.

Innovative ShockAbsorption Technology

Equipped with ShockDrop™ technology, the RockerBall™ dynamically absorbs jerking and jarring forces that occur when your trailer encounters bumps, potholes, or uneven surfaces. Unlike traditional metal-on-metal connections that transfer these disturbances directly to your tow vehicle, the RockerBall™ isolates and dampens them. This results in a smoother ride and reduces wear and tear on your vehicle’s suspension, brakes, and the trailer’s towing system.

Durable and Low-Maintenance Construction

Constructed from forged steel, the RockerBall™ offers exceptional strength and reliability, essential for demanding marine towing applications. The base features a durable carbide black powder coat finish, while the ball itself is chrome-plated for long-lasting weather resistance against harsh marine environments. Maintenance is effortless with no airbags or bearings to service—simply apply grease to the integrated zerk fittings to ensure continuous lubrication and smooth operation.

Easy Installation and Broad Compatibility

The RockerBall™ is designed to retrofit onto most standard ball mounts used with boat trailers. It fits virtually any mount with a 3-inch wide trailer ball tongue platform and a 1-1/4-inch trailer ball hole. The anti-swivel base ensures that the hitch ball remains properly oriented and securely locked in place once torqued, providing peace of mind during your towing adventures.
