CURT 2 x 1 RockerBall Cushion Hitch Trailer Ball - 7500 lbs [40047]

The CURT RockerBall™ trailer ball is a game - changer for towing. With our exclusive ShockDrop™ technology, it offers better comfort and greater control while you're on the road. This 2' x 1' trailer ball can convert a standard ball mount into a cushion hitch that stops rattles.

When towing, trailers going over bumps and potholes create all sorts of unpleasant vibrations, jolts, and noise. But the RockerBall™ reduces these jerks and jolts. Unlike traditional metal - on - metal connections that transfer all these annoyances to your tow vehicle, the RockerBall™ absorbs the erratic movements and rattles at the coupling point. This means a smoother ride, more control over your vehicle and trailer, and less stress on your vehicle, receiver hitch, brakes, and suspension system.

Compared to other torsion and cushion hitches, the RockerBall™ is super low - maintenance. It doesn't have airbags or bearings that need servicing. Just grease the integrated zerk fitting when needed for smooth operation.

This tow ball can be easily retrofitted onto many standard ball mounts. It fits any mount with a 2 - 1/2 - inch wide trailer ball tongue platform and a 1 - inch trailer ball hole. The anti - swivel base keeps the hitch ball in the right position when fully tightened.

Made from forged steel, the CURT RockerBall™ hitch ball is extremely strong. The base has a durable powder - coat finish, and the ball is chrome - plated for long - lasting weather resistance.

Using the CURT RockerBall™ trailer ball is easy. First, make sure your ball mount meets the requirements - it should have a 2 - 1/2 - inch wide trailer ball tongue platform and a 1 - inch trailer ball hole. The mounting platform needs to be at least 3/8' thick, and the hole size shouldn't be more than 1/16' larger than the diameter of the threaded shank. Then, retrofit the RockerBall™ onto the ball mount. Tighten the anti - swivel base fully to keep the hitch ball in place. When towing, enjoy a smoother ride as the ball reduces the impact from bumps and potholes. As for maintenance, it's very simple. There are no airbags or bearings to service. Just apply grease to the integrated zerk fitting when it's needed for continuous lubrication and smooth operation. Remember, the ball mount is sold separately and isn't compatible with the Rebellion XD ball mount. This trailer ball has a limited lifetime warranty, with a one - year warranty on the finish and parts.
