Features to know about

Smooths Out the Ride: ShockDrop Core Absorbs Road Vibration

Every bump and pothole sends shock through your truck and trailer. The Curt Rebellion XD’s built-in ShockDrop core compresses around a flexible polyurethane isolator to take that hit before it reaches your rig. It cuts down on jerking, jarring, and chucking so the whole setup feels steadier on rough roads. The dampened movement helps reduce wear on your suspension and braking systems while making long hauls more comfortable.

Levels Different Trailers: Six-Position Adjustable Drop

Switching between trailers doesn’t have to mean swapping ball mounts. The Curt Rebellion XD has an adjustable head with six height positions so you can dial in the exact rise or drop every time. It offers up to a 6" maximum drop, letting you keep different trailers level with one mount. Just pull the two stainless steel pins, slide the platform where you need it, and lock it back in place—simple and solid.

Built for Heavy Loads: 15,000 lbs GTW Strength

When you’re towing big campers or equipment trailers, you want something that can take the strain. This solid carbon steel mount delivers with up to 15,000 lbs gross towing weight and 1,500 lbs tongue weight. The 2" ball handles 10,000 lbs GTW while the 2-5/16" ball is rated for the full 15,000 lbs GTW. It’s a dependable setup that holds steady even under serious load.

Made to Last: Textured Teridium Finish and Stainless Components

Towing gear takes a beating from rain, salt, and road grime. The Rebellion XD’s dark gray teridium finish fights corrosion while keeping a clean look over time. The stainless steel hitch balls and hardware add even more protection against rust. A built-in grease zerk lets you lubricate the internal isolator core for quiet, trouble-free operation through thousands of miles of towing.

Compatible With Everyday Accessories: Solid Fit for Extras

Need to run mud flaps or Rock Tamers? The Rebellion XD’s design provides about 3" from the hitch pin hole to the closest part of the mount face, leaving room for common accessories that require at least 1" clearance. It’s a solid fit for setups that need extra protection behind the tow vehicle without worrying about interference or rattling.

Big. Heavy. Dampens trailer feedback.

Fantastic mount. It is a little bit of work to adjust because of the dampening mechanism is so tight. However we used it to pull 8500 load across the country and it worked great.

Quick turnaround time from order to delivery-arrival. etrailer.com, the Amazon of trailer supply and service, very nice!



by:

Gets rid of all the road chatter. Absorbs big shocks from pavement transitions. Make long huals smoother.. Whish I had bought one earlier



by:

Another excellent product from Curt, worth the money!



by:

Very nice adjustable hitch for whatever hight you need too level your trailer and the cushion hitch is awesome.



by:

The new trailer hitch is awesome! I needed it to pull my new 3800 pound cargo trailer. And I chose etrailer over other purchase options because of the excellent service I always receive!



by:

Since I needed to get an adjustable ball mount for my truck hitch anyway I decided to spend the extra dollars and go with the Rebellion XD. Really glad I did because there are times when I trailer my boat or camper over gravel and dirt roads for miles that are less than ideal and this helps with the constant pounding. Solid and well built - handles anything I need to trailer.



by:

Top quality trailer hitch. You can't beat the load capacity and the quality of this trailer hitch. Good price too!



by:

It performed exactly as advertised. I hauled a 1,600 pound bull in full size horse trailer 80 miles and the ride was smooth. I had none of the bouncing I had using the standard hitch on previous hauls.



by:

Smoothed the ride out. I've only had about 400lbs in 2 place horse trailer but made a difference.
I lent it to a friend of mine who was taking a load of hogs to market and he was really impressed with the difference it made! It was just like nothing was behind him. He had commented to me how bad the trailer rode so I told him to try the hitch. It's on his list of must have items!
My only concern is clearance.



by:

I love this hitch! I drive an 01 2500 ram with leaf springs and my old hitch was a solid 8" hitch. My trailer weights about 5k lbs. With uneven road surfaces, my trailer and truck would pitch and jar as I was driving. An unbelievable difference with my new rebellion xd. So much smother. It's almost as if I wasn't connected to my trailer.



by:

The folks at etrailer.com were very helpful and professional in assisting me obtain an alternative to my initial order which was on back order until December due to the Covid-19 virus. I initially ordered the Curt Rebellion XD Shock-Absorbing Adjustable Ball Mount - 2" Hitch - 6-1/4" Drop - 15K with a 2" and a 2 5/16" stainless steel balls. Due to their diligence I was able to learn of the backorder status immediately. Consequently, they were able to provide a work around (chrome balls as opposed to stainless steel). While their dedication facilitated on-time delivery saving the day. I not only recommend them, but I will definitely shop with them again.

excellent



by:

Used this on a trip last year. Had a sway hitch to compare to with the same equipment. This definitely reduced the up/down pressure on the tow vehicle and allow the tow vehicle a better road stance than the other hitch. I followed the directions and greased it before first use. Maybe too much, so make sure you wipe the fill point after the first trip. :)

Got my new shock hitch, had my old hide away pulling my landscape and enclosed trailers until I got my new shock hitch when pulling my trailers you don’t even know that they are being polled no shake no rattle no jerking especially when you go across the railroad tracks love my new hitch

This ball mount has worked very well for me. Easy enough to adjust and secure when adjusted.



by:

So far so good. We tow an Airstream with a 950 pound tongue weight.



by:

I believe it helped with the ride. No more clunk when stopping. Would give it 5 stars if hitch size was 2.5. Love the adjustment. Wish they would make with equalizer bars. Would be cheaper than air shock and I wouldn't have to switch.



by:

Would not fit. The hitch measured as wide as 2.110" in several areas and was very uneven. I needed to use the hitch the next day, so I ended up having to grind down my brand-new hitch just to get it to fit into my new receiver.

There was also slag and several burrs inside the pin holes. I had to clean and chase the holes before the pins would fit properly.

  • Can Curt RockerBall be Used with Rebellion XD Ball Mount
    Hey Edward, thanks for reaching out! I recommend using the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount # C83WR as-is because adding the RockerBall will just add more potential for uncontrolled movement as they might work against each other. It would be better to use the RockerBall with a standard ball mount setup as opposed to the whole Rebellion system.

  • Is The Curt Rebellion XD Compatible With An Equal-i-zer Weight Distribution Hitch
    Hi Larry, The Curt Rebellion XD Shock Absorbing Adjustable Ball Mount # C83WR is not going to be compatible with the head of the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37120ET so you will need to use the Equal-i-zer shank. This system will definitely help with the sway you've been experiencing but you'll want to get a measurement of your fully loaded tongue weight before purchasing. This hitch is rated for 800lbs to 1,200lbs so it's likely going to be too...

  • Recommended 2" Ball Mount to Address a Jerking Sensation When Pulling a Trailer
    Hey Dan. If you positioned the hitch ball attachment towards the top of the Curt Rebellion XD Ball Mount item # C83WR you'd be level, assuming the 18" measurement you gave me is the height of your trailer's coupler. There is not a shorter version of the Curt Rebellion. A weight distribution hitch isn't going to address any of the jerking or bouncing you're feeling in your truck. For those issues, I recommend using the Gen-Y Phantom XT Adjustable 2-Ball Mount w/ Torsion Flex item # GY52VB....

  • Which Curt Rebellion XD Ball Mount for 2022 Ram 2500
    Hey Todd, so the Curt Rebellion cushioned ball mounts do a great job cushioning the ride quality when towing but the part # C83WR is for a 2 inch hitch which you probably don't have on your 2022 Ram 2500 so instead you'd probably want the part # C57UR which is designed for the larger hitch size of 2-1/2 inch.

  • Can Curt Rebellion XD Be Used With Reducer Sleeve On 2026 GMC Sierra 2500
    Hey Troy! Yes, you can use the Curt Rebellion XD # C83WR with a reducer sleeve like the # BTBRV64FR. This ball mount weighs 43 lbs so it is quite a bit lighter than the 2-1/2" version. What will you be towing?

  • Is Curt Rebellion XD Compatible With Weight Distribution Hitch
    Hello again Colton; the Curt Rebellion XD # C83WR is not compatible with any weight distribution hitch. Since the Shocker Hitch models don't have enough of a drop for your setup the only solution is going to be the Gen-Y. I don't know of any other products out there that will cover such a wide variety of trailers with a single ball mount. Your best bet would be to use the # GY72NR for anything with 400 lbs - 1,100 lbs of tongue weight and the # 325-GH-1125 for the larger trailers with...

  • Are Rock Tamers Compatible With Curt Rebellion XD Shock Absorbing Ball Mount?
    The Curt Rebellion XD Shock Absorbing Ball Mount # C83WR is compatible with Rock Tamers, but the only way to make sure you will have enough clearance is to measure from the center of the hitch pin hole to the front edge of your trailer hitch receiver. Rock Tamers like the # ERT00108 require 1" of clearance between the face of the receiver and the ball mount, so since from the center of the hitch pin hole to the closest part of the # C83WR measures 3" you will need to have a center of hitch...

  • Recommended Ball Mount W/ 5" of Rise for a Volvo XC90
    Rebekah, so unfortunately the Curt RockerBall # C40047 won't physically fit on your Curt Rebellion XD # C83WR so the two can't be used together. What you could do instead is, use the Curt Ball Mount for 2" Hitches # C45336 instead which will work with the Rockerball and has that 5" of rise you're looking for and then get the Replacement Sway Control Tab for Weight Distribution System # 3442 welded on so you can use a weight distribution system.

  • Will the etrailer Anti-Rattle Hitch Collar Work w/ the Factory Hitch on a Subaru Ascent?
    Hey Brian, thanks for the pictures. The etrailer Anti-Rattle Hitch Collar is not going to fit your Ascent's factory hitch. It's going to be a tight fit if you can even mount it with the chain hangers so close but the main issue is the side mounting pieces will block your hitch pin holes.

  • Are Rock Tamers Mud Flaps Compatible With Curt Rebellion XD
    Hi Dave; the answer to your question depends on your receiver. The Rock Tamers # ERT00108 require 1" of clearance between the back of the ball mount face and the trailer hitch receiver opening. The distance from the hitch pin hole to the closest part of the ball mount on the # C83WR is 3". As long as the distance from the center of your hitch pin hole to the face of the receiver is 2" or less this will work for you.

  • Gen-Y Torsion 2-Ball Mount VS Curt Rebellion XD For Towing 4,000LB Boat Trailer
    Since you have such a light boat trailer I recommend the Curt Rebellion XD # C83WR. This will work better with the lighter amount of tongue weight that you have of 400lbs. The hitch will also be much easier to use for you as it weighs only 43lbs compared to the Gen-Y Torsion 2-Ball Mount w/ Stacked Receivers # 325-GH-1024 which is more than double that at 71lbs. The Gen-Y will still work but for optimal performance out of their hitch they want to see 500lbs of tongue weight. The Curt...

  • Recommended Improvements To Reduce Trailer Bounce On Legend Aluminum Equipment Trailer Torsion Axle
    As your 24' Legend 12,000lb aluminum equipment trailer has torsion axles there is nothing that can be added to these to improve the bouncing that you have. Being that your trailer is constructed of lightweight materials and has such heavy duty axles the bouncing is amplified. This is why you did not notice a difference with the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount # C83WR. My only recommendation would be to see if your tires can safely be driven with a lower air pressure...

  • How to Reduce Trailer Bounce on Enclosed Trailer With Torsion Axle
    If your tongue weight is too light, and it sounds like you might be aware of the fact that it is, that is likely the problem. Adding weight to the front so you're at that 10-15% of the trailer weight would go a long way in reducing trailer bounce. If your trailer itself is really light and you aren't carrying heavy loads that could also be a part of the problem, so the extra weight would kill two birds with one stone. Since you have torsion axles you can't really add anything to the suspension...

    I reached out to Curt who stated at this time the cushioning material inside the Rebellion XD Shock Absorbing Adjustable Ball Mount # C83WR is not replaceable. They have tested the Rebellion to having more than 1 million cycles and the cushioning did not deteriorate.
