Towing can get rough when every bump and pothole transfers straight through the hitch. The Curt RockerBall with ShockDrop technology uses cushioned isolators around a flexible polyurethane core to soak up vibration and jolts before they reach your truck or trailer. It reduces shock loads during braking or acceleration and keeps everything steady for a smoother, quieter ride.
Nothing’s more annoying than hearing your hitch rattle on every stretch of road. This kit includes an anti-rattle pin and bracket that tighten the connection between the 2" shank and receiver, cutting down vibration and preventing sway. The result is a quiet, solid feel when you’re towing—no extra movement or clanking behind you.
The ball mount and base are constructed from high-strength forged steel for dependable towing power. A durable black carbide powder coat protects the mount, while the chrome-plated 2" ball resists rust and wear. It’s tested to meet SAE J684 safety standards and holds strong with a 7,500-lb gross towing weight rating and 750-lb tongue weight capacity.
Keeping your trailer level helps it track straight and handle better on the road. This mount provides a 3" drop or 2" rise, letting you dial in the right height for your setup. The overall length measures 8-1/4" from the center of the hitch pin hole to the center of the ball hole, giving you enough clearance for easy hookup.
The RockerBall’s built-in zerk fitting makes it simple to lubricate the isolator core whenever needed. There are no airbags or bearings to maintain, so it stays virtually maintenance-free while staying smooth and quiet over time.

This is great! After a year of wear and tear and plenty of travel time it's still going strong -- love to see that! Thanks for the review :) Where are you headed next with the camper?

This ball mount comes to us from the manufacturer as a kit, without the ball mounted to the ball mount. We do have a ball mount with a 4 inch that comes with the ball torqued. It is part # C45154.
Do you have a question about this Trailer Hitch Ball Mount?
