Curt Trailer Hitch Ball - C29FR

  • Trailer Hitch Ball
  • 2-5/16 Inch Diameter Ball
  • 1 Inch Diameter Shank
  • Shock Absorbing Ball
  • Curt
  • 12000 lbs GTW

Curt RockerBall with ShockDrop technology bolts onto your standard ball mounts to provide comfort and control while towing. Chrome ball has a 1-1/4" diameter x 2-1/8" long shank. Anti-swivel, forged steel base has black powder coat finish.


Features:

  • Hitch ball provides a connection point for your trailer's coupler
    • Fits most existing ball mounts
  • Integrated ShockDrop technology
    • Cushioned isolators reduce rattling and vibration for a more comfortable ride
    • Reduces shock loads to the vehicle during sudden braking or acceleration
    • Minimizes stress on tow vehicle's suspension and brakes for extended longevity
  • Fine threads provide tight, strong grip
  • Anti-swivel base is constructed of forged steel for dependable towing power
  • Durable carbide black powder coat finish on base
  • Corrosion-resistant chrome finish on ball
  • Virtually maintenance-free with no airbags or bearings to service
    • Built-in grease zerk makes it easy to lubricate when necessary
  • Tested for safety to meet SAE J684 specifications
  • Lock washer and nut included


Specs:

  • Ball diameter: 2-5/16"
  • Shank dimensions: 2-1/8" long x 1-1/4" diameter
  • Weight capacity: 12,000 lbs
  • 1-Year limited warranty


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.

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. 820623

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. 808839


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.

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. 865728

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 763701

  • Can Curt Rockerball be Used with Weight Distribution System
    I have a cushioned solution for your WD setup but you are correct the Curt Rockerball is not to be used with weight distribution systems according to Curt. The movement that the ball allows and the stresses of the WD system just don't allow the two to fit together and work. Instead you can use the cushioned weight distribution shank part # GY54FR for a 2 inch hitch which the head of your weight distribution system can attach to. There isn't any other option to cushion a weight distribution...

  • Is Convert-A-Ball Ball Mount Compatible With Curt RockerBall?
    The Curt RockerBall Shock Absorbing 2-5/16" Hitch Ball - 1-1/4" Diameter Shank # C29FR will not work with the Convert-A-Ball Ball Mount for 2" Hitches - 3/4" Rise, 2" Drop - 10,000 lbs # AMSC2 which has a 1 inch diameter ball hole. Using the Polyurethane of the Convert-A-Ball Ball Mount as well as a similar design in the ball may actually mitigate the shock absorption. One or the other would help but sometimes using two parts with the same thing will work against each other instead...

  • Can Curt RockerBall be Used with Weight Distribution
    Good question. I checked with Curt because I haven't had this come up yet but unfortunately no, the RockerBall, part # C29FR, cannot be used with a weight distribution system. Looking at your pictures I think you have a Blue Ox SwayPro system, like part # BXW0753. If I'm correct then you need a standard 2-5/16 inch ball with either a 1 or 1-1/4 inch shank. Beyond that the choice is yours so part # 63847 is a good option for a a 1 inch or part # 63840 for a 1-1/4 inch.

  • Will Curt Rockerball Fit on Weight Distribution Head?
    The Curt RockerBall Shock Absorbing 2-5/16" Hitch Ball - 1-1/4" Diameter Shank - Chrome - 12K # C29FR does not fit weight distribution heads because the base of the ball is meant to fit the rectangular platform. If you remove that part of the base it may work but it also could rotate so the shock absorbing may not work correctly.

  • Shock Absorbing Hitch Ball with 1-1/4 Shank and 2-5/16 Ball for 2 Ball Mounts
    If the trailer requires a 2-5/16 ball, you don't want to use the 2" ball to pull the trailer. The 2-5/16 ball has a larger shank so it is not interchangeable with the Curt RockerBall Anti-Rattle Towing Kit - 2" Ball - 8-1/4" Long Mount - 7,500 lbs Item # C63KR I recommend Curt RockerBall Shock Absorbing 2-5/16" Hitch Ball - 1-1/4" Diameter Shank - Chrome - 12K Item # C29FR and Curt Solid Ball Mount for 2" Hitches - 3" Rise, 4" Drop - 10" Long - 12K Item # C45313.
