Note: 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
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
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.
The built-in zerk allows you to lubricate the isolator core when necessary, ensuring quiet and trouble-free operation.

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!

Took it out on its first trip and it worked flawlessly. Was skeptical it would make such a big difference but it did. Really lesser the jolting and jarring that made my wife so nervous every time we took the trailer out.

See what our Experts say about this CURT Trailer Hitch Ball
- Should Hitch Ball Move Inside Coupler When Towing TrailerThe Demco # DM12563 is not made to be adjusted, but what you're experiencing is normal. There should be room for play to allow for the normal movement of the trailer. If it was tight it would not be able to move and pivot as intended. If you want to limit the jerk you feel in your vehicle, you might want to consider the Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047. This will help reduce the shock from rapid braking and acceleration. Just to make sure it is working properly,...
view full answer... - Recommended Ball Mounts For Curt RockerBall Shock Absorbing BallI may have an option for you but the Curt RockerBall Shock Absorbing 2" Hitch Ball part # C40047 is a 2" ball with a 1" diameter shank so this will not work for your ball mount with a 5/8" hole. If you would like to switch out your ball mount you can use the RockerBall with a ball mount with a 1" diameter I have attached a couple of ball mounts below that will work with the Rockerball since I am not sure how much rise/drop you need in a ball mount. Curt Ball Mount for 2" Hitches - 3/4"...
view full answer... - Curt RockerBall Shock Absorbing 2" Ball For 800LB Trailer Pulled by 2010 Subaru Forester 2" ReceiverI 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 3/4"...
view full answer... - Does Curt Rockerball Have to Be Used in Curt Ball Mount/HitchThe Curt RockerBalls like the part # C40047 do not require the use of a Curt ball mount or trailer hitch. They can be used in essentially any brand of ball mount or hitch.
view full answer... - Availability of Curt RockerBall Setup With Longer ShankThe only option that comes from Curt is the # C45WR with the 7-1/2" ball mount length. If you want a longer ball mount you would have to put one together. You could use the Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047 along with something like the # D-4 which is 10-1/4" long. Make sure to measure so you get the right length. Then you will need to attach the Curt Weld-On Sway Control Tab # C45822.

When we installed this hitch on a 2002 Sienna, we found that the distance from the ground to the top of the hitch receiver was 13-1/2 inches; since the bottom of the U-haul coupler is going to be 18-1/2 inches from the ground (that is what they mean when they say "optimal ball height" as that is how far off the ground the...
view full answer... - Shock Absorbing Ball Mount/Trailer Ball Recommendation for Pop Up CamperCurt offers a solution that would provide additional shock absorption to help isolate the tow vehicle from the shock the trailer experiences on bumpy roads, while still allowing you to use your existing # C45250 ball mount. The Curt # C40047 RockerBall is a 2 inch trailer ball with a 1 inch diameter shank that would be fully compatible with your existing ball mount. The ball has a 7500 lb capacity, so it'll work great with your pop up camper.
view full answer... - Aluminum Ball Mount and Cushioned Hitch Ball for Use with 2021 Kia TellurideTwo inches of rise would be the ideal amount based on the height differences you mentioned. When you can't get an exact number it's best to go a little taller since there would be some suspension sag from the tongue weight of the trailer. The rise/drop figure of a ball mount like the # DTBM4200 is factored with a standard hitch ball so you would not need to further calculate in a balls height as well unless you went with a taller ball. Now in the case of the Rockerball # C40047 this ball...
view full answer... - Curt Rockerball C4000047 Pivot Pin Diameter and Cushioning MaterialAccording to Curt, the # C40047 RockerBall Shock Absorbing 2 inch trailer ball uses a 9/16 diameter tipvot pin. The cushioning material is polyurethane and the ball has a 7500 lb capacity. If you click the provided link, you can see a product demonstration video featuring the # C40047 RockerBall.
view full answer... - Shock Absorbing Ball Mount With 2-5/16" Ball The Curt RockerBall Shock Absorbing part # C40047 only comes in a 2" ball at this time. You may consider using a ball mount like part # AMSC2HD that has a shock absorbing core with a 2-5/16" ball. The ball hole diameter is 1-1/4". If you need a ball with that size diameter shank I recommend part # 19286.
view full answer... - Is a New Ball Mount Needed To Use the Curt RockerBall Shock Absorbing 2 Hitch BallThe Curt RockerBall Shock Absorbing 2" Hitch Ball part # C40047 will add 1-1/2" of height to the ball platform so you will then indeed need to get a ball mount that has more drop or can be adjusted to have more drop. I have attached a list of our options below if needed. The Convert-a-Ball Adjustable-Height Ball Mount part # TK5007 is a great adjustable option.
view full answer... - Why Cant the Curt RockerBall Shock Absorbing Hitch Ball Be Used With a Weight Distribution SystemThe Curt RockerBall Shock Absorbing 2" Hitch Ball part # C40047 will not work with a weight distribution system because the flange that gets wedged between the platform and base that stops the unit from rotating will not fit over the shank on a weight distribution system. Therefore, the Curt RockerBall must be used with a standard ball mount like the Curt Ball Mount for 2" Hitches part # C45310. If you are looking to add a shock absorbing feature to your weight distribution system you'll...

view full answer... - Curt RockerBall and Convert-A-Ball Compatibility With A 5,000LB Boat TrailerThe Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047 cannot be used with a shock absorbing ball mount like the Convert-A-Ball Ball Mount # AMSC2. It can also not recommend by Curt to be used with surge brake couplers. I recommend using a standard style ball mount with a anti rattle hitch pin for a trailer that does not have a surge brake coupler. This can be found in a kit like the Curt RockerBall Anti-Rattle Towing Kit # C63KR. Remember that the RockerBall adds 1-1/2" to your receiver...
view full answer... - Will Curt C40047 RockerBall Shock Absorbing Hitch Ball Eliminate Most Hitch RattlingGoing with the # C40047 Curt Rocker Ball will help isolate some of the clattering and banging from the surge coupler, and it will also help dampen some of the road shock you experience. What it won't do is help with the movement of the ball mount in the receiver which is pretty unavoidable. Due to manufacturing tolerances, it isn't possible to get a tight fit between the ball mount and receiver, right out of the box. If the fit was too tight the ball mount would eventually become stuck...
view full answer... - Shock Absorbing Solution for Towing Lightweight Trailer with Class II Hitch ReceiverFor your application I recommend checking out the Curt RockerBall Shock Absorbing 2" Hitch Ball which comes with a 3/4" diameter shank as part # C94CR or with a 1" diameter shank as part # C40047. This unique hitch ball absorbs the shock at the connection between the hitch ball and ball mount which is perfect for a lighter application like what you have. Please note that 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...
view full answer... - Can Curt RockerBall be Used With Curt Channel Style Ball Mount C45901Yes, the two can definitely be used together; the Curt RockerBall is available with a 1" diameter shank like you mentioned, which is the same diameter as the hitch ball hole of the Curt Channel Style Adjustable Ball Mount # C45901. You can use either of the following 2" or 2-5/16" RockerBalls with this ball mount: - Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047 - Curt RockerBall Shock Absorbing 2-5/16" Hitch Ball # C82KR I have added links below to video reviews for you to...
view full answer... - Can the Curt RockerBall Shock Absorbing 2" Hitch Ball Be Used With Convert-A-Ball Ball Mount You could certainly use the Convert-A-Ball Ball Mount for 2" Hitches # AMSC4 together with the Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047. Whether it is pointless or not is dependent on what you are doing or experiencing right now. If you are getting/expecting a lot of bouncing, rattling, and vibration, then the combination will certainly help to reduce this. If you aren't, then it probably isn't necessary. Worst case scenario it isn't going to hurt anything, only help. My...
view full answer... - Does Curt RockerBall Shock Absorbing 2 Inch Hitch Ball Fit Channel Style Adjustable Ball MountYes, the RockerBall and channel style ball mount you asked about are absolutely compatible: - Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047 - Curt Channel Style Adjustable Ball Mount # C45901 The reason is, the ball mount accepts a hitch ball with a shank that has a 1" diameter and is at least 2-1/8" long, which is exactly the shank dimensions of the RockerBall. I have added links to video reviews of both parts for you to check out as well.

- Will Lucas Oil Marine Grease Work with Curt RockerBall Shock Absorbing 2" Hitch BallThe Curt RockerBall Shock Absorbing 2" Hitch Ball part # C40047 per the instructions requires a high-quality molybdenum-based grease. In other words, any grease with a moly base will work. I recommend the LubriMatic Moly EP Grease part # LM54FR. It looks like the Lucas Oil Marine Grease has a calcium sulfonate base so I cannot recommend this.

- 3 Inch Rise/4 Inch Drop Ball Mount for Curt C40047 RockerBall Trailer BallThe Curt # C84WR is 2-3/4 inches wide at the ball platform, so it won't work with your # C40047 Curt RockerBall. This being said, we do offer a ball mount with a similar rise/drop with a 1 inch diameter ball hole that would work. I'd recommend the Draw-Tite # 2753 which has a 7500 lb capacity, a 2-3/4 inch rise or a 3 inch drop.
