CURT 2-5/16 RockerBall Cushion Hitch Trailer Ball - 12,000 lbs [40249]

The CURT RockerBall™ trailer ball revolutionizes your towing. It comes with our unique ShockDrop™ technology, offering better comfort and control. An integrated cushion isolator transforms a regular ball mount into a cushion hitch that stops rattling. When you tow, the RockerBall™ significantly cuts down on jerking and jarring. As your trailer hits bumps and potholes, it usually creates vibrations, jolts, and noise. With a normal metal - on - metal connection, these issues transfer to your tow vehicle, making your ride noisy and uncomfortable. But the RockerBall™ absorbs the erratic movement and rattling at the coupling point. This gives you a smoother ride, more control over your vehicle and trailer, and reduces stress on your vehicle, receiver hitch, brakes, and suspension. Compared to other torsion and cushion hitches, the RockerBall™ is super low - maintenance. It has no airbags or bearings to take care of. Just grease the zerk fitting when needed for smooth operation. It can be retrofitted onto many standard ball mounts, specifically those with a 3 - inch wide trailer ball tongue platform and a 1 - 1/4 - inch trailer ball hole. The anti - swivel base keeps the hitch ball in place when fully torqued. Built from forged steel, it's incredibly 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 3 - inch wide trailer ball tongue platform and a 1 - 1/4 - inch trailer ball hole. The mounting platform must be at least 3/8 - inch thick, and the hole size shouldn't be more than 1/16 - inch larger than the diameter of the threaded shank. Then, retrofit the RockerBall™ onto the ball mount and fully torque the anti - swivel base to keep it in place. When towing, you'll notice a smoother ride as it reduces jerking, jarring, rattling, and vibrations. For maintenance, it's a breeze. There are no airbags or bearings to service. Just apply grease to the integrated zerk fitting as needed to keep it lubricated and operating smoothly. Keep in mind that the ball mount is sold separately and isn't compatible with the Rebellion XD ball mount. Also, the trailer ball is rated for 12,000 lbs gross trailer weight, so don't exceed this limit for safety. And it has a limited lifetime warranty with a one - year warranty on the finish and parts.
