Two Different Mounting Options

The ShakeStopper gives you the flexibility to mount your hitch above or below your RV bumper. You can mount your hitch receiver below the bumper if your camper body hangs over your bumper. You can also mount it above to give your bike rack or cargo carrier an extra 6" of clearance to avoid scraping on uneven surfaces when entering or leaving parking lots or crossing roads.


Hitch-Clamping Design

No more loud, shaky rides and damage to your bike rack or cargo carrier. Unlike conventional bumper-mounted hitches that often tighten down the shank using set screws that cause instability and dents, the ShakeStopper has a unique clamping design that firmly holds your bike rack or cargo carrier in place to help reduce noisy rattling and avoid damage to your shank from rocky, bumpy rides.


The shank is held in place between a 1/4" steel base plate and 2 free-floating pressure plates. The heavy-duty retention bolts are used to tighten the pressure plates down, creating a clamping force to reduce movement of your hitch-mounted accessory. The base plate helps distribute the load when the pressure plates are engaged to prevent denting and other damage. Shank locks in place with a 5/8" hitch pin and clip (sold separately).


No Load-Bearing Fasteners

Most bumper-mounted hitches use load-bearing fasteners, such as U-bolts, to carry the weight of hitch-mounted accessories, like a bike rack or cargo carrier. The bolts can easily dent your bumper if over-tightened and tend to loosen over time, causing your hitch to bounce and shake while driving down the road, leading to more damage on your bumper. This unique design was constructed with a retention fastener to firmly clamp the side plates and base plate around your bumper to reduce the risk of damage.

Well made. Love it. Locks down my bike rack good and solid.
by:
Worked Awesome! Had to heavy electric bikes on it and went through some rough road. Held up great!
by:
I use this for a cargo carrier. The metal bumper tore at the welds and my carrier tilted down and was dragging on the freeway. This hitch never let go. I didn't lose any of my stuff. I had to have a new bumper welded on. My hitch was transfered over to the new bumper and is still working great.
by:
Pretty easy to install. Directions had detailed pictures and instructions. It seems far more sturdy than the one I had. the U-bolt broke sometime last year. I didn't know it until I went to trade in my camper and saw it. So this seems far better engineered.
by:
Holding on tight. My rack is heavy duty even though I never overload it, the receiver is very easy to install and is solid not shaky if installed properly.

I bought this "shakeStopper" about a year ago, so here is my story: My plan was to mount on the "tube" style bumper (Lance 2285) so I could install a bike rack to hold two E-bikes. A "black widow" rack (75#) and (one E-bike 45# after the batteries removed) so approx 170#. Madden voyage of 300 miles and the "tube" bumper failed at the welds due to the weight. The Shake Stopper saved the rack and bikes from being a total loss. The Shake Stopper is stout/heavy duty and easy to install. Just a reminder that most "tube" bumpers are not designed to support much weight, so use discretion on what you use it for. Wound up buying a new class III bumper from etrailer and its is amazing... etrailer is my go to for trailer parts. So I rated the Shake Stopper as 5 star for the quality and design! My tube bumper failure was no fault of etrailer.

Ready a well built piece of hardware !

Works perfectly! I watched the video versus reading the assembly directions and it was super easy to put together. It works great for our spare tire carrier. Great upgrade from the one we had!
by:
Great customer service so helpful and willing to go the extra mile for customer!
by:
Mounted it on an 4" RV bumper per directions. I ordered this model because it was rated for well over my intended use. I installed a 45 lb rack and carried a 119lb Generator. Nothing else. I watched it very carefully. It started to collapse. Don't trust it for over 100lbs period!

I am sorry to hear about your experience with this hitch. Could you tell me a little bit more about how it "collapsed"? I am wondering if something happened or if maybe the weight was not distributed properly that caused this.

Works great with our travel trailer to keep our trailer hitch cargo carrier stable. I did replace the original bumper with 3/16 inch square tubing rather than the flimsy bumper that our pull behind came with so I would not recommend this product on a "standard" travel trailer 1/16" bumper.
by:
It is like assembling a puzzle but once it is the fit on the bumper is great. The reason I gave it 4 stars is it only mounted on top of the bumper. I wanted to mount it under the bumper for access door clearance. If you don’t align it with the doors you can have interference issues.

Works as advertised , easy to install

  • RV Bumper Hitch Recommendation for Carrying 2 Bike E-Bike Rack
    Hey Danny, what you would want is the ShakeStopper Heavy Duty 2 inch hitch part # MNT72VR which has a 400 lb tongue weight capacity and was designed with heavier bike racks in mind. The hitch you mentioned only has a 100 lb capacity so it would not be what you'd want.

  • Will ShakeStopper Heavy Duty 2" Hitch MNT72VR Work For Carrying E-Bikes On A Travel Trailer?
    Hey Mark, thanks for reaching out. Yes, the ShakeStopper Heavy Duty 2" Hitch Receiver # MNT72VR can work for carrying e-bikes, but there are a few things you'll want to consider. The main limiting factor here is the capacity of your bumper. Adding support brackets definitely helps, but you'll want to be sure the bumper is adequately rated for the weight of your bike rack and both bikes. Also, not all e-bike racks are suited for use on a trailer, so you'll want to be sure your rack is...

  • Can I Mount the wagman Traveler XC2 Bike Rack to a ShakeStopper Heavy Duty 2" Hitch Receiver
    Thanks for your question, Frank. Yes! You can use the Swagman Traveler XC2 Bike Rack # S64663 with the ShakeStopper Heavy Duty 2" Hitch Receiver for 4" RV Bumpers # MNT72VR. You don't have to use the bumper-mounted hitch that comes with the Swagman rack, since it's compatible with any 2" hitch receiver. One nice thing about going this route is that if you have a 2" hitch on one of your vehicles, you can use the same bike rack there as well when you're not out adventuring with your camper. What...

  • Hauling E-Bikes With The Rear Bumper Of A 2007 Keystone Cougar 276RLS
    Hi George, Most OEM bumpers are typically 4" x 4" so you could just go with the the # MNT72VR instead and add on the Mount-n-Lock SafetyStruts Universal RV Bumper Support Brackets # MO34VR to increase the capacity of the OEM bumper to 400lbs. If that's not what you're wanting to do then yes, you could install both the ShakeStopper # MNT82VR and one of the 5.3" Heavy Haul'r bumpers to increase your capacity to haul some e-bikes: Mill Finish # MNT88VR Brushed Finish # MNT33VR Glossy...

  • Will The ShakeStopper Bumper Hitch MNT72VR Work For Carrying Two Electric Bikes?
    Hey David, thanks for reaching out. The ShakeStopper Heavy Duty 2" Hitch Receiver for 4" RV Bumpers # MNT72VR can absolutely work for carrying a few electric bikes. The hitch itself has a 400 lb capacity so that will be more than enough. The real limiting factor here is the weight capacity of your bumper. Bumper capacities can vary so you'll want to check with a dealership and verify your bumper can hold the weight. As long as the bumper is up to the task, and you get a good RV rated bike...

  • Spare Tire Mount for 2020 Jayco Greyhawk 29MV
    Hi Robert, sadly there isn’t a front mount hitch available for your 2020 Jayco Greyhawk 29MV Prestige Edition. Jayco also does not recommend adding a front hitch because it can affect airflow through the grille. A good alternative is to use a bumper mounted hitch like the ShakeStopper Heavy Duty 2 inch Hitch Receiver for 4 inch RV Bumpers, part # MNT72VR, along with the etrailer Spare Tire Mount for Hitch, part # e98ZR. I really like the ShakeStopper for this type of setup because it...
