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.
