- Ultra-Fab Products
- Silver
Designed for tandem-axle trailers with up to 10-1/2" wheel spacing, these wheel chocks will rid your rig of rocking by stabilizing your trailer or RV. Simply place the chocks between tandem tires and expand them until the give is gone.
Features:
- Wheel chocks eliminate give between tandem-axle tires to prevent rocking when parked
- Pivoting louvers on arms grip tire tread to prevent slipping
- Included E-Z ratchet makes it simple to expand units
- Lockable to deter theft - padlocks included
- Heavy-gauge steel construction
- Corrosion-resistant zinc plating
Specs:
- Application: RVs with up to 15" wheels
- Collapsed width:
- Center of chock: 1"
- Ends of chock: 5"
- Fully extended width at ends of chock: 10-1/2"
- Quantity: 2 wheel chocks
- Lifetime limited warranty
Note: The purpose of the Super Grip Chock is to limit front-to-back motion on parked tandem-axle trailers. Do not use as a brake or a wheel wedge.
Eliminate the annoying rocking of your trailer or RV no matter where you park it. The Super Grip Chock braces your tandem wheels against one another, stabilizing your trailer even on uneven terrain. No more front-to-back motion.
Pivoting Louver Technology
The pivoting louvers allow the Super Grip Chock to get a stronger grip on your tires as they hug the surface of each tire. The raised ridges grip onto the tire tread to keep the chock from slipping. The louvers can also swivel to conform to the exact curve of your tires, creating a better grip on the tires. As a result, the Super Grip Chock is able to apply the force necessary between the tires to provide excellent stability for your trailer or RV.
Mounting the Super Grip Chock
The included E-Z ratchet makes it fast and easy to set up the Super Grip Chock. Simply place the chock, in the open position, between the tandem tires of your trailer and use the ratchet to turn the nut on the rod until the width of the unit fits the spacing of your tires. Once the chock is firmly in place, lock it with the included padlock.

These things work great! I have found it is best to install them before you disconnect the trailer so that nothing moves when you take your trailer from the hitch. It also eliminated that little shimmy you got when you walk forward and aft in the trailer. These chocks are a “must have” in my book.
by: Howard04/05/2020
They work perfect in holding my trailer.
I ordered them as a pair with locks . The locks are little like what should be used on toys or luggage and as a pair ,they aren't keyed alike.

The supper grip chock wheel stabilizers are a great product. I have purchased two sets, one for myself and one for my in-laws. Quality construction and easy to use.

They do the job. Easy to use.

eTrailer is a great place to purchase your trailer equipment. I rated the wheel chocks a 4 as it assists with trailer rock but not completely. However, they do help.
by: Nathan L.08/21/2017
The chocks work great only reason for the 4 stars is the locks that came with the chocks don't fit very well, and the wrench that was included with them slips. I Replaced the wrench with a good ratcheting open end from the local hardware store and all is good.
by: Steven01/05/2018
These RV stabilizers arrived lightning fast. They were the best price on the internet by far and it took me maybe 15 minutes to install them. This is the second product I've purchased from eTrailer. Since we live in our RV right now, without a doubt I'm impressed with this company and will always consider their products before others.
Thanks,
Steven & Christina

Easy to use
by: Joe 03/24/2023
These chocks are great. They are fairly quick to setup and provide better roll security than traditional wedge blocks plus the benefit of limiting trailer rocking. The only negative we’ve noticed is that the ratchet/wrench provided to secure them is low quality and the ratchet has worn out. Nonetheless I would definitely purchase these again.
by: Craig 08/16/2023
too soon to tell but I can tell a difference inside the trailer. I hope they last.
by: William11/02/2021
once again your product did exactly it was suppose to. it took just a minute to install them and they steadied the trailer from any back and forth movment.

I still have nothing but good things to say about them. I have recommended them to other campers and will continue to do so
by: David02/13/2023
As always, etrailer exceeds expectations. I placed my order Friday and the x-chocks shipped on Saturday! Fabulous customer service.
Will update the performance once spring hits and we're back out camping.
by: Mark04/23/2023
They fit my 2013 Chevy Express conversion van. Took a little more squeezing then I expected to get the clip bolt and nut to thread together. That bolt and nut are plastic. I expect over time they will either cross thread or simply wear out. Should have been a metal bolt and nut.
by: Michael11/25/2022
Seems like a well made product, but I think they could have put a bit more thought (and engineering) into the locking provision for the adjusting nut. If you're going to go to the trouble of making it difficult for unauthorized loosening (i.e. theft) then go ahead and make it more "meaningful". Example...the cheesy toy padlocks are about as secure as a zip tie. Otherwise seems like it will serve the purpose. These are going to be to help provide additional rolling resistance when my trailer needs to be unhitched on a slight incline in front of my home (in addition to 4 heavy duty wheel chocks of course)!
by: Charles08/18/2022
They work well. But less than one year old and the bolts that hold it together are showing rust.
by: LRS07/13/2021
As the instructions state the Super Grip Stabilizers are a little stiff at first to operate, otherwise they work to help tire movement when there is movement inside the camper. Wish the locks were keyed alike as I bought them as a pair. The loop handles are a nice feature with no open ends to hang up on anything. Like that they are made in the USA!

I should use them more than I do. If the stay is just over night it is not worth the hassle to put them on.
by: Herman04/15/2018
The Super Grip Wheel Chocks are the best items I have ever purchased. They are easy to install between the tandem tires and keeps the trailer from moving when hooking up or unhooking the trailer from my truck. I wish I had pictures to show how glad I am now. We purchase a new 42' foot 5th wheel trailer and put it on the spot where the other trailer sat, almost at the edge of a 45 foot drop. I now feel VERY secure that it won't go anywhere. I was a tractor trailer driver for over 44 years, so I know the importance of stationary security to keep the unit from moving.

Im glad I purchased the chocks, the are where I had to set our 5th wheel has a 60 foot [] behind it.
by: GQ08/13/2017
Quick and easy to use, however don't trust them solely to keep your rig from moving. Had an incident about a week ago when I was using just them to chock my toy hauler but while unloading my second MC the trailer moved backwards some and the tounge support slid off their blocks. Fortunately no one was injured and only slight damage to the tongue support. These are good but I will always use in addition to my original wheel chocks.

These Ultra-fab wheel stabilizers are designed to prevent rocking of the trailer when it is parked and to deter theft. They are not intended to replace wheel chocks/wedges or brakes. We do recommend to use additional wheel chocks such as Anderson wheel leveler and chock part # AM3604.

by: Ron Kammer08/22/2017
Jacks are easy to install and remove although a little difficult to get centered correctly between tandem wheels. I am a little disappointed in experiencing some movement in trailer yet when jacks are installed despite experimenting with tension on tires.

The wheel stabilizers are only designed to keep the trailer from rocking while parked and to deter theft. They are not intended to take the place of wheel chocks/wedges or brakes for the wheels. Although these wheel stabilizers work well for what they are designed for, we always recommend to still use additional wheel chocks to keep the trailer from rolling. I recommend Andersen Camper Wheel Chock and Leveler part # AM3604.
by: Shane Ellison10/03/2022
I purchased these along with a king pin tripod for a 2021 Grand Design 31MB. We immediately noticed a difference with limiting any residual movement in our 5th wheel. We have three kids, and this is a must! Thank you e-trailer for your awesome customer service and detailed information on items!
by: EricR09/09/2017
Looking for something to secure my 24' travel trailer. I had inexpensive plastic block type wheel chocks that just didn't work the way I wanted them to. These secure the trailer, steady movement previously present with ground chocks, just elevates the sense of security when parked on any slope. Handy rachet included is a bonus.

Use these on every trip out with the travel trailer. Even got a bigger trailer last spring!
by: Mike10/29/2016
The brackets work perfectly for my dual axle trailer. Helps to keep the rocking to a minimum. The down side, the ratchet that comes with them is junk. It lasted for two trips the would not work anymore (tried to lube etc still will not work). Thank goodness that I had my tool kit with me so could get these off. The two star rating is because of the ratchet. Using my tools these work perfect.

Mike, thank you for your review and your business. We are sorry to hear of any inconvenience with your ratchet and have forwarded your review to our customer service team to see if we can resolve this for you.

Wrench that comes with it broke by its six installation.

Great website makes it easy to find what your looking for, lots of info that helped me make sure I got what I wanted. Got the parts when they said I would, the wheel chocks work awesome on our 26 ft traval trailer and way sway control mounted easy with instructions, also there were some helpful videos available if needed. I will definitely check Etrailer first for anything I need from now on.

Still working excellent no problems what so ever when people in the camp ground ask where to find items for their camper or truck I tell them to check out Etrailer.com
by: Mark M.10/25/2016
I took them out of the box and installed them on my trailer. They seem to do what they are supposed to do, and the price was reasonable.
I chose Ultra-Fab over other brands because of my positive experience with Ultra-Fab products.
The chocks arrived in three days with E-Trailer's free shipping. Great service.

- Where to Measure for the Fastway ONEstep Wheel ChocksI cannot recommend you elongate the holes on the Fastway ONEstep Wheel Chock part # FA84-00-4000 as this would void the warranty. However, if the tires you have now are 16"apart where the wedges sit then it will work for you. If you are looking for something that is more suited for a smaller tire spacing I recommend the Super Grip Chock Wheel Stabilizers part # UF21-001091 which fits tires up to 10-1/2" apart (center to center). This option installs a bit differently than the ONEstep but...

- Will the Super Grip Chock Wheel Stabilizers Work With 9-1/2" SpacingThe wheel spacing is measured from the closest point of each tire and if that's within 10-1/2" then yes, the Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers part # UF21-001091 will work great.
view full answer... - Should I Use One Super Grip Chock Wheel Stabilizer Or Two To Stabilize My Trailer?I always use the Super Grip Chock Wheel Stabilizer # UF21-001090 as a Set # UF21-001091. This will prevent the trailer from pivoting on the chocked tires. It will also allow you to use them to secure your camper at your site and while in storage. These chocks will spread up to 10-1/2" at the widest point. This measurement will be 5" up or down from the tires narrowest point. If you have a wider spread than 10-1/2" they have the Super Grip Chock XL Single # UF21-001094 and Set # UF21-001095...
view full answer... - Landing Gear Stabilizer Recommendations for 2020 Sabre Fifth Wheel 36BHQI recommend the MORryde 5th Wheel Cross Brace Landing Gear Stabilizer, # MR72AR that permanently attaches to your fifth wheel's landing gear reducing movement while parked. After installation, the braces will extend and retract with your landing gear, simply hand-tighten the tubes to increase stability. For the rear of the 5th wheel, I suggest the Valterra Folding Manual Stabilizer for Trailers and RVs, # 020106. This fits RV's with 14" to 28" of frame-to-ground clearance. You can also...
view full answer... - Reducing Movement in a 5th Wheel Trailer While ParkedMovement is normal when it isn't controlled. But when stabilization products are used then the movement can be reduced if not eliminated. You mentioned that you have tried things to correct this problem but did not mention what those things were so some of my recommendations may be something you have already tried. First we have to determine the nature of the movement. Is it side to side, front to back, or both? The front to back movement can result from slight movement at the trailer...
view full answer... - What is the Distance Range for Fitting Super Grip Chock Wheel Stabilizers On Tandem AxleThe chock kit part # UF21-001091 is designed to fit tire spaces from 1 inch to 10-1/2 inch. If you have 1-5/8 inches this should work well with that. Tire pressure for the tire should be the max pressure listed on the sidewall. You'd want to inflate them when cold. As a general rule of thumb it is recommended to keep a minimum of 4 inches between the front and rear tires of a tandem axle trailer. I would recommend finding a way to get the distance between your larger. You may need to...
view full answer... - Using a Wheel Lock on a 5th Wheel Trailer with a Goose Box Adapter InstalledA wheel lock in this case would be something like the Club Tire Claw XL Wheel Lock # WI491KA-491LNP or, even better, Super Grip Chock Wheel Stabilizers # UF21-001091 (which includes padlocks). The Super Grip option will also help prevent front to back rocking of the trailer. I have linked video reviews of both of these products for you.
view full answer... - Recommended X Wheel Stabilizers for Trailer With 2" Tire SpacingThe Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs part # UF21-001091 have been confirmed to fit trailers with a tire spacing under 2" so they will work great for you.
view full answer... - Wheel Chock Stabilizers For Trailer's And RVs With Wheel Spacing Of Up To 17"We do have plenty of other wheel chocks available for you to check out like the: -Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs # UF21-001091 which fits RV's and trailers that have a wheel spacing of up to 10-1/2", or, -The Super Grip Chock XL Wheel Stabilizers for Tandem-Axle Trailers and RVs # UF21-001095, which fits RV's and trailers that have a wheel spacing of 3-1/2" up to 17". If you let me know what wheel spacing you are needing for your coach, I'd be happy...
view full answer... - Can EZ-JACK Be Used Along with Adjustable Wheel StabilizerYou can use the # EZ-JACK leveler along with an adjustable steel wheel stabilizer like # UF21-001091 (and like the one shown in your photo) but since the stabilizer and the 3-inch tire spacing will not allow the taller part of the # EZ-JACK to fit between your tires you will lose some portion of its leveling range. You will probably be limited to 2 or 3 inches of its 6-inch height range. Moving the stabilizer to a higher point between the tires will free up slightly more space for the leveler.

- Stabilizer Recommendation for Tandem Axle Trailer with Lipper Ground ControlI'd go with a wheel stabilizer setup like the Super Grip Chock Wheel Stabilizers # UF21-001091 as it will lock the wheels together and remove the movement you have left. I attached a review video for you to check out as well.

- Wheel Chock Recommendation for Preventing Tandem Axle Trailer From Moving Back When HitchingI'd go with the part # UF21-001091. It locks the tire of each axle so well to each other that the trailer would not roll at all if pushed while you were hitching up. I attached a review video for more info. If you wanted to be super cautious a standard wheel chock like part # FT11933MI would also help.
view full answer... - Recommended Wheel Chock for a Tandem Axle Trailer with Tires That are 10 inches ApartI have a couple of different options for you to use chocks that are compatible with the 10 inch space between your tires. My first recommendation is the Super Grip Chock Wheel Stabilizers # UF21-001091. This chock system can fit wheel spacing from 1 inch - 10-1/2 inches. If that 1/2 inch of leeway is not enough for you, we also have the Super Grip Chock XL Wheel Stabilizers # UF21-001095 which fit wheel spacing from 3-1/2 inches - 17 inches.
view full answer... - How to Prevent Rocking and Swaying While Parked on a Jayco Travel TrailerIn order to further stabilize your Jayco travel trailer, I recommend additional jacks and wheel chocks. The best way to minimize swaying and rocking would be to have a total of four stabilizer jacks, one for each corner of the trailer. If you do not already have four stabilizer jacks you can use part # UF48-979031 for the front or rear depending on where the jacks you have are located. Once you have jacks on all four corners you add further support using the Super Grip Chock Wheel Stabilizers...
view full answer... - Are Two Camco Premium Locking Wheel Stops CAM44662 Needed for 25-Foot TrailerOne of the Camco Premium Locking Wheel Stops # CAM44662 will effectively prevent the trailer from rolling. But adding a second one on the other side of the axles will further stabilize the trailer and help to reduce any wander from half the axle being unsecured. If you want a set of two you might prefer part # UF21-001070 or part # UF21-001091 from Ultra-Fab. These wheel stops will not be as effective as the trailer's actual stabilizer jacks at reducing roll of the trailer when you walk...
view full answer... - Recommendations for Improving Stability of Travel Trailer at CampsiteThe stability of your travel trailer is improved by making sure your RV is level, wheels choked, and your Lippert High-Speed Power Stabilizer Jack, # LC298707 extended appropriately on a wood or block base and not the bare ground where they can sink. I suggest using the Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers, # UF21-001091 and Stackers Leveling Blocks w/ Bag for Trailers and RVs, # A10-0920. Position these beneath your wheels to level the travel trailer and under...
view full answer... - Which Set of Super Grip Chock Stabilizers Fits 16 inch Diameter WheelsSince your wheel size is 16 inch the correct set of Super Grip Chock XL Wheel Stabilizers is the part # UF21-001095 as the kit you mentioned fits smaller diameter wheels and would not work.
view full answer... - Stabilizer for Fifth Wheel Trailer That is Lived InWhile there is an option for stabilizing your 5th wheel trailer that you are living in, the TrailerLegs Tire Saver Stands # 326-TRLLG-4 do require a tow vehicle to install and are also for when your trailer is in storage as opposed to being lived in. I recommend checking out the Ultra-Fab Economy 5th Wheel King Pin Tripod Stabilizer - Steel - 31" to 54" # UF19-950500 because it is a great way to stabilize your trailer while also being very easy to use. It is for king pins that are 31"...
view full answer... - Recommended Products To Stabilize Grand Design Reflection Travel Trailer When CampingFor your Grand Design Reflection 312BHTS I recommend the Ultra-Fab Slide-Out Supports # UF19-960002. Since your Reflection has the 2 opposing slides that carry the weight of most the kitchen and the seating areas the trailer is virtually teetering on itself with the weight hanging over the sides of the trailer. These supports will allow you to stabilize that additional weight where it matters at the edge of the slide rather than at the frame which is inside the wheel footprint. Be sure...
view full answer... - Wheel Stop Style Chocks for Tandem Trailer with 1-1/2 inches Between TiresFor a distance of 1-1/2 inches between the tires we have the Ultra-Fab Chock and Lock Wheel Stabilizer # UF21-001060 which would work great, the part # UF21-001091 you referenced has a minimum of 5-1/2 inches so it would not work.
view full answer... - Super Grip Chock Wheel Stabilizers for Tandem-Axle TrailersThe Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs, # UF21-001091 are designed by Ultra-Fab an American owned company and outsourced for manufacturing. These are a great solution to prevent the tires from rocking and causing front-to-back motion when you are parked and inside the camper. I've attached a review video of the Super Grip Chocks for you.
view full answer... - Socket Size for Super Grip Chock Wheel StabilizersThe Super Grip Chock Wheel Stabilizer for Tandem-Axle Trailers and RVs # UF21-001090 weighs about 5 lbs; it is also available as a pair of stabilizers at part # UF21-001091. The socket size is 17mm and it does come with an E-Z ratchet if you need or want to expand it manually. I have added links to a couple video reviews of the stabilizer for you to check out as well.

I like these stabilizers because the pivoting louvers help provide a better grip on the tire's tread to better stabilize the trailer. I've attached a review video of the Super Grip Chocks for you.
view full answer... - How Much Do the Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs WeighThe Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs part # UF21-001091 weigh about 5 lbs each or 10 lbs for the pair.
