The CURT RockerBall™ trailer ball provides improved comfort and enhanced control while towing, featuring our unique ShockDrop™ technology. An integrated cushion isolator allows this hitch ball to turn a standard ball mount into a cushion hitch with anti-rattle capabilities.

The RockerBall™ trailer ball dynamically reduces jerking and jarring while towing. As your trailer passes over bumps and potholes, it produces all kinds of vibrations, jolting, chucking and noise. With a traditional metal-on-metal connection, these annoyances are directly transferred to your tow vehicle, making your ride noisy, uncomfortable and taking a toll on your towing system.

The RockerBall™ completely changes your towing experience by absorbing the erratic movement and rattling of your trailer at the coupling point. This provides a smoother ride and increased control over the vehicle and trailer. It also reduces the amount stress placed on your vehicle, receiver hitch, brakes and suspension system.

The RockerBall™ is also extremely low maintenance compared to other torsion hitch and cushion hitch options. It has no airbags or bearings to service. Simply apply grease to the integrated zerk fitting as needed for continuous lubrication and smooth operation.

The RockerBall™ tow ball retrofits onto a variety of standard ball mounts, virtually 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 properly oriented and locked in place when fully torqued.

The CURT RockerBall™ hitch ball is constructed from forged steel for exceptional strength. The base is covered in a durable powder coat finish, and the ball itself has a chrome plating for long-lasting weather resistance.

    Rockerball

    This thing is great. It takes the jerk out of hailing on rough roads and road crossings. Can’t even feel railroad crossings like I use to. I would definitely recommend this product.

    ROCKERBALL REVIEW

    The ROCKERBALL REALLY WORKS! I used it when pulling a large enclosed trailer to my move my daughter to college. My passengers even commented "puling this trailer seems like a breeze". I educated them it wasn't the trailer, it was the Rockerball. No noise, no jerks - smooth sailing. Great Product, keep up the good work.

    Curtis Trailer hitch

    First off I wanna say thank you to the representative that handed these hitches out at Anderson Motor Speedway. I wouldnt have known about them if it wasn't for them being there.
    Back to the Curtis hitch. I love it i paid $150 for a drop down plate and a brand new 2" clevice style hitch and wasnt happy because one setting was to high and drug my tail of the trailer on the concrete. The other setting was to low and it will drag landing gear. But with this curtis hitch its absolutely perfect. Bare minimum scraping while in use. Also makes the load easier while pulling with the rocker ball. I will recommend this product to anybody. Thanks for this opportunity.

    Curtis Trailer hitch

    this is one of the best hitches I've owned. You don't feel your load as bad because of the forgiveness of the ball. Im glad I got to try o e of these and will pass by word of mouth to people who never has tried it

    ShockDrop does the job.

    Towing my 15' aluminum boat with a heavy Yamaha 4 stroke made the tongue have no weight, so the previous ball mount set up would just rattle and make noise. ShockDrop does the job it says, it isolated the rattle and made a nice quite ride to the late.
    Thanks Curt
