  • Weight capacity: 7,500 lbs
  • Rocker base dimensions: 2-1/2" long x 2-1/2" wide
  • 1-Year limited warranty


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.


Shock Absorbing ShockDrop Technology

Curt RockerBall with SockDrop Technology

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.


Premium Construction

Curt RockerBall Construction

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.


Curt RockerBall Zerk Fitting

The built-in zerk allows you to lubricate the isolator core when necessary, ensuring quiet and trouble-free operation.

Works great, it's a noticeably smoother ride than other hitch balls I've used.




by:

Was impressed when I used it, then I had my son move the truck while I watched and saw the movement, great product




by:

Best ball on the market




by:

I purchased this to test out. I’m using it on a Ford Ranger and towing a 6x16 enclosed trailer. Curt makes great products I’m sure it won’t disappoint.




by:

It looks like a quality product, but after buying 3 different drop hitches for my truck it doesn't look like I will ever find one that it will fit on............. so I just bought a stainless ball and went on. Makes for a nice $[XX] paperweight or conversation piece.




by:

It does seem to make a smoother ride. I tow a 20 foot cargo trailer which gets quite heavy at times.

Review from a similar RockerBall in Trailer Hitch Ball


Took it out on its first trip and it worked flawlessly. Was skeptical it would make such a big difference but it did. Really lesser the jolting and jarring that made my wife so nervous every time we took the trailer out.

Review from a similar RockerBall in Trailer Hitch Ball


Changed over from the conventional Ball. Noticeable difference after installing Rockerball. Makes the ride quieter and when braking no noises and no trailer play when braking or accelerating. recommended Product.

Works Great. No wear or tear on the Rockerball and I’ve used it well over 25 times. Good as Mew.

Review from a similar RockerBall in Trailer Hitch Ball


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.


Comments
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

Review from a similar RockerBall in Trailer Hitch Ball


Like most any lock they can be a little temperamental after being out in weather a while, but a shot of lock lube or WD40 takes care of that. "Training the lock to your given key is a breeze, and I definitely like the convenience of not having to try and recall which key is needed to use them!

We have a small trailer pulling behind an SUV. This really cuts down the rocking as we drive.

Review from a similar RockerBall in Trailer Hitch Ball


Received product before due date however, both our WD Hitches do not have the standard piece to allow the Anti-Rotation Plate to be useful. Pictures attached.
Checking with etrailer to see what can be done before modifying either the ball or the hitches. Only other issue was packaging, it was well packed on bottom side but not on top which allowed the product to distort the box it was shipped in but it did come fully in tact with no visible harm. Mentioning this for future delivery of such items.


Comments
I was able to contact Curt and the Curt RockerBall is not compatible with weight distribution systems. It is only compatible with a ball mount that has a 1-14 diameter ball shank hole.

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.

Review from a similar RockerBall in Trailer Hitch Ball


Good idea, though actual towing feels chaotic. Pulling a 4,500 pound camper trailer with a F150 - Max Tow Package and this hitch causes the trailer to surge back and forth when braking, accelerating and/or rolling over bumps in the road. I don't know if my hitch is defective or not, but I will not be using this hitch anymore. The other issue is, when torquing the ball hitch to the specified 450 ft/lbs - the flanges that are supposed to hold the ball in place bent and I had to find an alternative to secure it from turning.

Review from a similar RockerBall in Trailer Hitch Ball


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.
