45949 Curt Rebellion Shock Drop Dimensions

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 Rebellion XD ball mount.


Shock Absorbing ShockDrop Technology

Curt ShockDrop Technology

The Rebellion XD ball mount features Curt's innovative ShockDrop technology, which is engineered to suppress vibrations and rattling while you're towing. It can even help limit sway. When you hit a bump, the ball mount compresses around the built-in, flexible polyurethane core. This durable material absorbs excess shock 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.


Unlike other shock-absorbing systems, which use air bags that require constant monitoring or bearings that are subject to excessive wear, the Rebellion XD is nearly maintenance-free. And it's tested for thousands of cycles to ensure lasting efficiency.


Adjustable Height

Curt Adjustable Ball Mount

The Rebellion is built with an adjustable shank that lets you raise or lower the ball platform to get the rise or drop that you need for your setup. No more swapping out ball mounts to tow different trailers.


To adjust the height of the Rebellion XD ball platform, remove the 2 stainless steel pins and clips and slide the platform along the shank to the desired position. Six positions allow for plenty of versatility so that you can use this ball mount with all of your towing setups. Re-insert the pins once you've found the correct height and replace the clips to secure them in place.


Premium Construction

Curt Ball Mount Premium Construction

The Rebellion XD is built to last with its solid carbon steel construction and premium teridium finish. The flexible, shock-absorbing polyurethane core withstands extreme heat for long-lasting performance. Stainless steel hardware provides superior durability and corrosion resistance.


Curt Ball Mount Grease Zerk

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

Ask the Experts about this Curt Trailer Hitch Ball Mount

  • Can Sway Control Be Added To The Rebellion XD Shock Controlling Hitch
    I contacted Curt on your behalf to look at what options you have to use a sway control system with Curt Rebellion XD Shock Absorbing Adjustable Ball Mount # C45949-2516. They did not have a solution allowing both a conventional sway control solution and the Rebellion hitch to be used together. A simpler option instead is the Hayes Sway Master Electronic Sway Control System # HA81775 that provides sway control through your trailer brakes. It is mounted on your trailer and does not...

  • Does Curt Rebellion XD Shock Absorbing Adjustable Ball Mount come with 2 5/16 Ball Installed?
    The Curt Rebellion XD Shock Absorbing Adjustable Ball Mount # C45949-2516 comes with a 2- 5/16" ball, but it is not pre-installed. This is a great option for anyone towing heavier loads up to 15k lbs. or who pulls multiple trailers with different heights. The ball mount does not come with a hitch pin. If you do not already have one, I recommend the MaxxTow Hitch Receiver Lock part # MT96FR to keep the slick black look and provide additional security. Check out the videos below for an...

  • Weight Distribution Shank Replacement that is Cushioned
    Sounds like you have a weight distribution system and are looking for a way to cushion the ride quality for your rougher roads. For that we have the cushioned weight distribution shank part # 325-GH-1202 which fits all standard weight distribution heads and uses torsion springs to cushion the ride quality when towing.

  • Can the Curt Rebellion XD Shock Absorbing Ball Mount Be Used With a Weight Distribution System
    That's a good idea but sadly I don't think Curt nor Equal-i-zer would permit using the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount part # C45949-2516 with an Equal-i-zer Weight Distribution System like part # EQ37100ET. That said, if you are looking to soften the ride I would first try to release some tension from the spring bars but if this then causes you to sag too badly you could look into installing shocks on the trailer, the Lippert Components Bolt-On Shock Kit part #...

  • Can the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount be Used with Weight Distribution
    The Curt Rebellion XD Shock Absorbing Adjustable Ball Mount part # C45949-2516 is an excellent option for towing as it has built-in cushioning which does a great job of absorbing road shock thereby proving a smoother ride. In regards to weight distribution, this ball mount is not compatible. In regards to whether or not a system should be used, this really comes down to how well the truck can handle the trailer. We recommend using one if the weight of the trailer (while loaded) is more...

  • Is There a Weigh Safe 2-Ball Mount For a Trailer Over 10,000 Lbs
    It sounds like you are looking for a Weigh Safe 2-Ball Mount like part # WS6-2. That said, this Weigh Safe 2-Ball Mounts that fit into a 2 inch receiver will max out at 12,500 lbs due to the aluminium construction so none of them will work for you. The reason for this as noted is that the aluminium construction simply cannot handle the weight which is why you will need to look into a steel ball mount. I recommend the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount part # C45949-2516...
