CURT (40247): RockerBall™ Cushion Hitch Ball

The CURT RockerBall™ is a world-first cushion hitch trailer ball that can be bolted onto an existing, traditional ball mount to increase comfort, confidence, and control while towing.

Engineered with ShockDrop™ technology, the 40247 RockerBall™ dynamically absorbs jerking and jarring from your trailer at the coupling point. This produces quieter towing; increased driver control over the trailer; and reduced strain on the vehicle’s brakes, towing system, and suspension as compared to a conventional metal-on-metal towing connection.
