CURT 40047 RockerBall Cushion Hitch Trailer Ball 7,500 lbs, 2-Inch Diameter, 1-Inch Shank

The CURT RockerBall trailer ball is a cushion hitch ball that dynamically absorbs jerking and jarring from your trailer at the coupling point. Just bolt it onto your existing trailer hitch ball mount to enjoy increased comfort, enhanced control and extended longevity of your vehicle's systems. The RockerBall tow ball is engineered with ShockDrop technology: a cushion isolator that reduces noise, vibrations and chucking 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, compared to a conventional metal-on-metal towing connection. The RockerBall fits onto a variety of standard ball mounts -- virtually any ball mount with a 2-1/2-inch wide trailer ball tongue and 1-inch diameter ball hole. RockerBall is also virtually maintenance-free. Unlike other cushion hitch and torsion hitch options, it has no airbags or bearings to service. Just apply grease to the zerk fitting as needed for continuous lubrication and smooth towing. The RockerBall trailer ball is constructed from forged steel for exceptional strength, and it comes with a powder coat finish and chrome plating for dependable corrosion resistance.
