Slightly Off Axis Curt Rockerball

Updated 08/12/2026 | Published 08/09/2026

Question:

I have a 1inch shank Rockerball on Curt hitch mount. After tightening to torque specification there is a slight rotation of the ball assembly. The anti rotation plate is installed correctly and not damaged. Is this cause for concern?

Hey Brad, this is a great question but your Rockerball part # CU46FR being slightly off will not be a problem. It will still function like it needs to and your ride quality will be greatly improved. I'm curious if after you use it the first time if it happens to straighten itself out though.

The picture shows it after about 30 miles of towing. I thought about taking the RockerBall off and inserting a shim between the tabs and hitch mount edge to hold the rotation plate parallel during reinstallation.

@Brad can you feel it making the ride smoother at all?

@Brad Yes, ithe ride is quieter and smoother. I can feel the RockerBall cushioning the hitch connection. I use a light coating of grease on the ball as recommended.

@Brad that's great to hear. I wouldn't worry about the ball being slightly misaligned. It's close enough that it will still work great and won't cause any issues.
