Notes:

  • All RockerBall hitch balls will sit 1-1/2" higher than a standard hitch ball due to their shock absorbing base.

  • Not to be used with a cushioned ball mount.

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.

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.

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.

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.

Really delighted at fast delivery and quality of product as well as ease of installation. Worst part was getting old bolt off but was my kind of switch-over and I needed the extra 1 1/2 inches because I was a little heavy on the tongue for my boat. Would recommend

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.

Ask the Experts about this Curt Trailer Hitch Ball

  • Curt RockerBall Shock Absorbing 2" Ball For 800LB Trailer Pulled by 2010 Subaru Forester 2" Receiver
    I have a recommendation as the 3,500lb Curt RockerBall # C94CR is only designed to be used with 1-1/4" Class I and II ball mounts. Since you already have 2" draw bars/ball mounts you can use the 7,500lb Curt RockerBall # C40047. This will fit your 2-1/2" wide mounts. This will work with your trailer even though it is only 800lbs. Do not be overly concerned with the weight ratings as these are maximum weight ratings and the reason the other RockerBall is so low at 3,500lbs is the...

  • Do Curt Rockerballs of Different Weight Capacities Have Similar or Different Dampening
    The dampening is different between the higher and lower rated Curt RockerBalls. Based on your trailer being lighter I'd recommend the part # C94CR that you mentioned even though the roads you plan to travel on are rougher. This will give you the smoother ride quality over the higher rated option.

  • Curt RockerBall for 2015 BMW 328xi Wagon
    Yes, the Curt RockerBall # C94CR meets your needs of a 2" Hitch Ball. This has a 3/4" Diameter Shank that is 2-1/8 Inch in length. If you need a drawbar for your 1-1/4" hitch I suggest the Curt Class II Drawbar # C45521.

  • Calculating Rise/Drop Ball Mount to Use with Curt Rockerball Hitch Ball
    So the Curt Rockerballs like the # C94CR sit about 1-1/2 inches taller than standard balls. And most rise/drop calculations are measured at the base of the ball and not the top so that changes the 16 inch height to be right around 14 inches for how our ball mounts are organized/measured. So then subtract the 1-1/2 inches of the Rockerball puts the height instead at 11-1/2 inches which is right at the 11 inches of your hitch opening. So that would mean you'd want a rise of right at 1/2 inch...

  • How Much Rise Does Curt Rockerball Give Ball Mount
    The Curt Rockerballs like the part # C94CR add 1-1/2 inches of height compared to a standard ball so if you used this with a ball mount that has 2 inches of rise like the # C45270 that you referenced you'd effectively have a 3-1/2 inch rise. So for the amount of rise that you want your best option would be the part # C40047 for a Rockerball since it has a 1 inch shank diameter and then the Draw Tite ball mount # 80232 which has a rise of 3/4 inches. This would get you really close...

  • Recommended Hitch Ball and/or Ball Mount for Shock Absorption
    For your ball mount if you have a 1-1/4 inch shank, then the Curt RockerBall Shock Absorbing 2" Hitch Ball - 1" Diameter Shank - Chrome - 7.5K # C40047 or the Curt RockerBall Shock Absorbing 2" Hitch Ball - 3/4" Diameter Shank - Chrome - 3.5K # C94CR is your best option. If you have a 2 inch receiver shank, the above hitch balls are an option, however most other shock absorbing options will have more of a drop than you wanted for ground clearance. For instance the Convert-A-Ball Dual-Cushioned,...

  • 1-1/4" Ball Mount Capable of 7" of Total Rise With 2" Ball
    I have a solution for you to be able to get to 7" of total rise. The Brophy Anti-Rattle Drawbar # BR39FR is a 1-1/4" ball mount that will give you 5-1/2" inches of rise. That is the largest rise that I have been able to find. You can couple that with the Curt RockerBall Shock Absorbing 2" Hitch Ball # C94CR. It will fit the 3/4" hole in the Brophy ball mount. The ball does sit 1-1/2" taller than a traditional hitch ball thanks to the shock absorbing mechanism. This will also give...

  • Recommended Ball Mount To Get 6" Of Rise For a 2015 Chrysler 200 Class I, 1-1/4" Receiver
    Currently our Curt Drawbar # C45028 has the most rise available for a 1-1/4" Class I receiver like that you would have on your 2015 Chrysler 200. The rise is 5-3/8" from the receiver. To get slightly closer to your 6" rise you can use a Curt Class I Drawbar # C45025 with a Curt RockerBall Shock Absorbing 2" Hitch Ball # C94CR. The ball mount has a rise of 5" and the RockerBall sits 1-1/2" higher than a traditional 2" ball. As long as your trailer accepts a 2" ball this would give you...
