CURT RockerBall Cushion Hitch Trailer Ball | 2" Ball, 3/4" Shank, 3,500 lb

The RockerBall trailer ball dynamically absorbs jerking and jarring from the trailer right at the coupling point. It bolts onto your existing ball mount, so upgrading is as simple as swapping the ball, with no airbags or bearings to service.

Inside, a cushioned isolator with ShockDrop technology reduces noise, vibration, and chucking compared to a conventional metal-on-metal ball connection, which means a quieter ride, better driver control, and less accumulated stress on the tow vehicle's suspension and brakes. It's built from forged alloy steel with a powder coat and chrome-plated finish for corrosion resistance.

• ShockDrop cushioned isolator dampens jerking and jarring from bumps and potholes
• Reduces rattling and vibration for a smoother, quieter tow
• Cuts shock loads to the tow vehicle during sudden braking or acceleration
• Fits standard ball mounts with a 2-inch ball and 3/4-inch diameter hole
• Forged alloy steel with chrome-plated, polished finish
• Rated for 3,500 lbs

Maintenance is limited to greasing the zerk fitting as needed; there's no cushion hardware to replace over the life of the ball.
