Specs:
Note: All RockerBall hitch balls will sit 1-1/2" higher than a standard hitch ball due to the shock absorbing base.
The mounting platform on your ball mount must be at least 3/8" thick and the hole size must not be more than 1/16" larger in diameter than the ball's threaded shank.
Towing can be brutal, especially when your setup is outfitted with standard, metal-on-metal components. Steel and aluminum can only absorb so much vibration and chucking, so every time you hit a bump in the road, that shock gets transferred to the rest of your rig, leaving it vulnerable to wear and tear. Another unfortunate side effect is an uncomfortable ride for you and your passengers.
Protect your truck and trailer from road shock, vibrations, and rattling - and stay comfortable while you drive - with the shock-absorbing Curt RockerBall hitch ball.
The RockerBall hitch ball features Curt's innovative ShockDrop technology, which is engineered to suppress vibrations and rattling while you're towing. When you hit a bump, the ball compresses around the flexible, polyurethane core. This durable material absorbs excess shock at the coupling point so that it doesn't transfer from the truck to your trailer or vice versa. The result is increased control and comfort as you tow, as well as less wear and tear on your towing setup.
This hitch ball is built to last with its forged steel construction and durable powder coat finish. The flexible, shock-absorbing polyurethane core withstands extreme heat for long-lasting performance, and the chrome-plated ball resists corrosion.
The built-in zerk allows you to lubricate the isolator core when necessary, ensuring quiet and trouble-free operation.

I have used it probably 20 + times over the past year & it has worked great. No more slamming back & forth when starting and stopping. Would definitely purchase again.
