CURT (45143): RockerBall™ Cushion Hitch with 2” Ball

Using exclusive CURT ShockDrop™ technology, the RockerBall™ cushion hitch transforms your towing experience by absorbing erratic trailer movement and rattling at the coupling point, providing a smoother ride and increased control and reducing the stress placed on your vehicle, receiver hitch, brakes, and suspension.

Unlike a traditional metal-on-metal connection that directly transfers vibration, jolting, chucking, noise, and wear to your tow rig, the RockerBall™ features an integrated cushion isolator that dramatically reduces jerking and jarring as you navigate bumps and potholes. And, with no airbags or bearings to service, the RockerBall™ is a low-maintenance dream that needs just a little zerk grease as needed.

Boasting forged-steel construction, a protective powdercoat, and a chrome-plated ball, the 45143 CURT kit includes a 2” ball mount with a 3” drop and a 2” shank to fit most class 3, 4, and 5 receiver hitches. An included anti-rattle shim kit ensures maximum vibration resistance.
