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.

I ordered this due to a video "Playing with Sticks" by Drew. The ordering, shipping, and delivery was prompt. I have not used the product yet so I have no feedback on that. Once I have used it I will addendum the product.



by:

So far it’s perfect for my needs. It is light weight and sticks out just past my spare tire on Bronco.



by:

I really like this. The additional height is just right to provide excellent weight distribution and prevents the jarring impact of the road, stopping and starting. I add grease regularly to maintain function.



by:

Great addition to any hitch, cushions the bumps, especially in glorious stop and go traffic on memorial day!



by:

I didn't know what i was missing with this rocker ball from Curt. It has proven to provide a smoother towing experience!



by:

I would most definitely,not recommend this product at all. Not blaming the seller, as they took it back, and I just got a solid ball from them instead. Pulling a 26’ cargo trailer, (nothing extremely heavy), the rocking ball would violently, “slam back” while taking off from a stoplight, and would violently “slam forward” when stopping for one. Literally thought the ball was going to snap off, it slammed so hard.

Best ball on the market



by:

Have not tested yet, but looking forward to trial.



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:

love using the rocker ball



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:

This was a great purchase. Works perfe ctly



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:

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:

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:

Great company to work with. Their employees are very knowledgeable and nice to work with.



by:

Stops bumping in truck as you stop v



by:

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.
