Curt RockerBall with ShockDrop technology provides comfort and control while towing. Corrosion-resistant, black powder coated ball mount measures 9-1/4" from center of hitch pin hole to center of ball hole. Includes anti-rattle kit.
Features:
Specs:
Note: The hitch ball will sit 1-1/2" higher than a standard hitch ball due to the shock absorbing base.
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.

Great product!
This all-in-one kit does everything it promises to do. I wish I'd learned about it sooner.
So I’ve been wanting the rocker ball for a while now and I’ve finally bought it. I bought the kit and it comes with a regular curt hitch, anti rattle kit, and the Rocker Ball. Construction seems solid on all Items. The hitch did arrived with a small area the size of half a penny of the powder coating chipped. I think it might’ve occurred during transit. Installation is fast BUT and a big BUT is very difficult to keep the rocker ball aligned to the hitch while you are torquing the nut. Mine ended up being noticeable sideways when I finished torquing it. I had to try it a couple of times and even then I couldn’t torque it all the way without 1. The rockerball assembly going sideways and 2. Without the tabs on the metal bracket bending.( one corner did bend. Anyways seems like a good product and if you don’t care of the Rockerball not being sorta aligned ( I honestly think that it shouldn’t be of fwhen fully tightened because then the rocker ball is not going to move straight back and straight forward) then I supposed it’s ok... If you are like me that gets bothered by details like this then find something else. I would’ve returned it but I scratched the hitch trying to get the Rockerball sorta aligned. Anyways take my experience with a grain of salt and good luck.
The hitch works great as advertised. A great company to deal with along with their prices.
This Curt towing kit has worked flawlessly. The reduction in rattling and jerking is quite noticeable (compared to my standard hitch set-up). My primary use of the Curt kit has been the towing of my teardrop camper; logging thousands of miles already with no problems, and no problems anticipated. The only thing now, a year later, is that the chrome on part of the RockerBall in contact with the hitch has worn off, but this is not surprising to me. I am quite satisfied with this product.
This was a game changer for us. The previous hitch receiver made so much noise and we felt the trailer a lot more over bumps than we do with this new hitch. Highly recommend.
Works great. Eliminates the rattle.
Works great!! No thumping on starts and starts. Excellent service too!
Ball is not mounted. Pictures and videos show ball mounted. And when I have bought a “kit” in the past, the ball was mounted.
I can’t attach the ball myself and only reason I purchased from eTrailer was that pictures implied that the ball would be mounted.
Somewhat disappointed in Curt with this product and I have always been a big Curt fan. The first one of these I ordered was the listed 3" drop unit. The base of the rocker ball is almost 1 7/8" tall so on a 4 inch drop ball mount its really only a 2 inch drop hitch so be aware when ordering. I had to send the first back and reorder the larger drop unit. When I received the larger drop unit I put it in the receiver like many other hitches I have used and proceeded to properly torque the ball down. Because the rocker ball has a pivot point its very important that it stay parallel to the receiver. Curt includes a sheet metal plate that shims in between the ball mount and the ball to prevent it from turning. The plate is no where near strong enough though and at 224 ft/lb the plate bent and the ball rotated. After the plate is bent it is almost impossible to get he thing torqued down right and lined up.
Took an extra day to get it, but everything came in as promised and in one piece!
Another satisfying transaction =)
Nice solid piece with weight. The only issue I have is that the ball is only secured down with a bolt and not lockable to prevent theft.
Heavy-duty hitch! Customer service in finding the right one at etrailor was excellent!
Very good quality and fast delivery.
Great

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.
