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

Pivoting Louvers

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.

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.

I purchased these chocks as a recommendation from KeepYourDaydream. To my surprise, these chocks came with the ratchet tool as well as a flip top cover and padlock! Put these chocks in and the trailer is not going anywhere!!

Working very well!!

I love it! Easy to install (less than 2 minutes) and fits my trailer perfectly. It gives me a great comfort to know that my wheels are locked in place and secure. Also I did not realize until I opened the box that locks and ratchet are included!

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!

These super grip chocks made a big difference in stabilizing my 32' travel trailer. I would highly recommend these for anyone with a pull behind RV!

I have an enclosed car hauler to store my boat/trailer in. The trailer use to rock as I was putting my rig inside. This doesn't happen anymore with these wheel chocks. I feel a lot safer now when putting my fishing rig inside the trailer. great idea on stabilizing the trailer.



- UF21-001091

Look like they will work great, but the adjuster bolt came completely unscrewed from the nut. I staked the end of the threads of the bolt after threading thru the nut. This will prevent it and possible loosing the nut and washers.

We love this product, definitely helps the trailer to stop moving and putting them on and taking off is so easy!!!!!!

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

Great product, helps to stabilize the camper and I do not have to worry about the camper moving if the campsite is not as level as I like it.

Easy to set and adjust. Heavy duty. Expect to get years of service.

I have made 4 moves since purchasing these and highly recommend them. Easy installation and removal. These will reduce trailer movement when parked.


Comments
Work great for stabilization. But if you forget to remove them the bend easily and cannot be used.. I have replaced the first set already and they are working great.

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.

Very prompt service from E-Trailer. Even though this product was on back order they got my order out as soon as it arrived. E-Trailer is my first go-to for automotive, travel trailer, and bicycle accessories!



- UF21-001091

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.



- UF21-001091
by:

These are to replace an old pair that had the screw sieze in place. The old ones worked perfectly and these are much smoother than them.

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.


Comments
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.

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.


Comments
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.

I had tried numerous things to stop my rv from rocking everytime someone moved inside and nothing work until I got this product. They made a 100 percent improvement on my rv stability and stopped the rocking. I recommend this product and would buy again.

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.


Comments
Use these on every trip out with the travel trailer. Even got a bigger trailer last spring!
