Regular ball mounts send every bump straight through your truck and trailer. Curt’s RockerBall with built-in ShockDrop technology changes that. The flexible polyurethane core cushions vibrations and jolts, reducing noise and harsh feedback. It keeps towing comfortable and prevents shock loads from hammering your suspension and brakes when you hit potholes or brake hard.
The right height makes all the difference for stable towing. This mount gives you a 5" drop or a 4" rise so you can match your trailer’s coupler height perfectly. That means your setup stays level, your load stays even, and you get steadier handling on the road. The shank fits 2" x 2" hitch receivers, giving you a solid, standard connection point that’s easy to set up.
Nobody likes a noisy hitch. The anti-rattle kit included with this setup keeps movement tight between the mount and receiver. A threaded pin locks everything in place to stop vibration and sway before it starts. Once it’s snugged down, the result is a quieter tow with less clunking when you accelerate or stop.
Towing gear lives a tough life—rain, salt, and road grime all take their toll. This RockerBall kit uses forged steel construction for dependable strength rated at 7,500 lbs gross towing weight and 750 lbs tongue weight. The black carbide powder coat on the shank and chrome plating on the ball resist rust for long-term durability. It’s tested to meet SAE J684 safety standards and backed by a limited lifetime warranty for peace of mind.
With no airbags or bearings to maintain, this hitch ball is practically maintenance-free. When it needs attention, the built-in grease zerk fitting lets you lube the isolator core quickly to keep things operating quietly and smoothly season after season.
The hitch ball will sit 1-1/2" higher than a standard hitch ball due to the shock absorbing base.

Great product!
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.
This all-in-one kit does everything it promises to do. I wish I'd learned about it sooner.
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.
Great
Very good quality and fast delivery.
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!
Works great!! No thumping on starts and starts. Excellent service too!
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.
Works great. Eliminates the rattle.
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 hitch
NO RATTLING when pulling trailor

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.
