CURT 2" RockerBall Cushion Hitch Trailer Ball - 3500 lbs

The CURT RockerBall™ Cushion Hitch Trailer Ball is engineered to deliver superior towing performance for marine and boating enthusiasts. With a robust 3,500 lbs capacity, this innovative hitch ball ensures a smoother, quieter ride by minimizing vibrations and shocks, enhancing your boating experience whether you're towing a trailer to the marina or hauling gear on rugged terrains.

Enhanced Towing Control with ShockDrop™ Technology

The RockerBall™ trailer ball integrates CURT's exclusive ShockDrop™ technology, providing dynamic reduction of jerking and jarring motions during towing. This advanced system absorbs vibrations caused by uneven surfaces, such as bumps and potholes, ensuring a stable connection between your boat trailer and tow vehicle.

Key Benefits for Boating Applications

• Smoother Rides: Absorbs erratic movements, reducing noise and enhancing comfort during your journey.
• Improved Vehicle Longevity: Decreases stress on your tow vehicle’s suspension, brakes, and hitch, extending their lifespan.
• Enhanced Safety: Provides better control over your trailer, especially during sudden braking or acceleration.
• Low Maintenance: No airbags or bearings require servicing—simply lubricate the integrated zerk fitting for optimal performance.

Durable Construction for Marine Environments

Built from forged steel, the RockerBall™ guarantees exceptional strength and reliability. The base features a durable carbide black powder coat finish, while the trailer ball is chrome-plated to resist harsh marine conditions, ensuring longevity and consistent performance in saltwater environments.

Easy Retrofit Compatibility

The RockerBall™ seamlessly retrofits onto most standard 2-inch wide ball mounts with a 3/4-inch trailer ball hole. Its anti-swivel base maintains proper orientation and stays locked in place under high torque, making installation straightforward for boat trailers.
