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.

Another satisfying transaction =)
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.
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.
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 hitch ball works great no slamming back & forth when stopping are starting. Just the right height for my F150 with a 4 inch curt drop receiver. I would definitely purchased again. Ran it with an unloaded trailer & a trailer with weight around 2500 lb. You want be disappointed in the purchase.
I was in the market.
Looking for some kind of dampening hitch.
But all the hitches I found We're over $300. I stumbled upon the Curt rocker ball . It was interesting to me so I had looked up some reviews on it. There wasn't any good reviews on it, but there also wasn't any bad reviews either.
So I decided to give it a shot,
Since it was pretty Inexpensive. Since then, I've had it for a year and a 1/2 now And it's been amazing.something so simple,That works very well. You won't notice it as much if the trailer already tows very well But the trailers that do a lot of jerking You will feel the difference.
A night and day difference.to me it reduced it by By 80%. Very good 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.
Can kinda tell the difference when I pull a bumper pull trailer
Couldn’t ask for better service. Lauren A. went above and beyond to ensure that my shopping was pain free. With today’s customer service being what it has become, it’s encouraging to see the customer comes first. Will continue to buy through etrailer. Thank you Lauren.
I just purchased a new hideaway hitch system. But the hitch sits only 15 inches off the ground at best. And, my trailer coupling is 22-23 inches off ground. So l needed 7-8 inches of rise on the new 1.25 inch receiver system.
Internet research took me to etrailer and the Brophy hitch. I got 5.5 inches with the Brophy hitch, the highest available for a 1.25 inch receiver I could find. The others are limited to 5 inches max. I added another 1.5 inches with your Curt shock absorbing hitch. Voila, with a combined 7 inches of rise and on level ground the trailer now rides perfectly level!!!! Both parts were very easy to connect.
Delivery was speedy. Thank you for saving the day and my investment in an expensive new hideaway hitch!
High Quality Part. Easy to install. I would buy again for another vehicle.
P.S. etailer.com did a great job getting me this part. They processed & shipped this order immediately. I also appreciate that they made it easy to track the shipment. Thank You etrailer.com, I WILL be placing more orders from your company. Thanks again.
Quality products. But the added height of this Curt shock absorbing rocker ball in combination with the 5-1/2” height Brophy bar, I still bottom out and scrape the inclined road to my house while towing my boat.
on our NEW Ram 1500 truck this ball helps reduce the trailer vibration that gets transferred into the truck. it definitely helps with a smoother ride.
Have not tested yet, but looking forward to trial.
This ball has worked very well for use with our 2016 Honda CR-V. It added some extra height we needed and is quiet. Would definitely recommend.
Great quality and price.
Greatest difference is felt with a full trailer vs empty. For reference, I haul a 3700 horse trailer and with one or two horses on board, this makes a noticeable difference in the reduction of ‘jolts’ when road seams, potholes are encountered. No noticeable difference when empty, but I am rarely empty. Good value for outcome.
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.
Drove from San Diego to Alaska - smooth ride w/trailer...
I received my order one day late but everything turned out good and I already tried out the ball hitch and lock assembly and seems to tow pretty good so far
Works great in taking out the "jolt" when making quick stops and starts

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.
