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.

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

Have not tested yet, but looking forward to trial.

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.



by:

love using the rocker ball



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.



by:

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



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:

I thank it is everything that it should be. Works great



by:

Best ball on the market

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!



by:

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.



by:

Can kinda tell the difference when I pull a bumper pull trailer



by:

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!



by:

Took an extra day to get it, but everything came in as promised and in one piece!

Another satisfying transaction =)



by:

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.



by:

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.



by:

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.
