Designed for tandem-axle trailers with up to 10-1/2" wheel spacing, this wheel chock will rid your rig of rocking by stabilizing your trailer or RV. Simply place the chock between tandem tires and expand it until the give is gone.


Features:

  • Wheel chock eliminates 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 unit
  • Lockable to deter theft - padlock 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: 1 wheel chock
  • 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.

  • Can the Super Grip Chock Wheel Stabilizer Be Used To Hold a Trailer On a Slope/Incline
    The Super Grip Chock Wheel Stabilizer for Tandem-Axle Trailers part # UF21-001090 is more of a stabilizer than a wheel chock. Therefore, you can still use these to help prevent the trailer from rocking etc. but in order to hold the trailer in place on an incline/slop you'll need an actual wheel chock. The Rumber Wheel Chock Set part # RM57FR is what I recommend as they are very heavy duty and easy to use due to the included chains.

  • Recommended Stabilizer Jacks for a 2001 Fleetwood Wilderness Travel Trailer
    In order to help stabilize your 2001 Fleetwood Wilderness Travel Trailer I recommend using two sets of the Scissor Stabilizer Jacks w/ Handle part # TJSCHD-24, one of each side of the trailer as this will provide the most stability. These jacks are easy to install and might even use the same holes as the jacks you have now. They offer up to 18-3/4" of lift and have a 2,500 lb per jack rating. If you really wanted to fully stabilize the trailer then you could also add a set of the Super...

  • Socket Size for Super Grip Chock Wheel Stabilizers
    The 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.

  • 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...

  • Preventing Theft Of 5th Wheel Trailer Using Convert-A-Ball Cushioned 5th-Wheel-To-Goosenck Adapter
    The traditional gooseneck coupler locks like the # BLTL-53-40D2 will not work on this adapter. We do have a few solutions though that will help with theft reduction though. First you can loosen the set screw that holds the inner coupler tube in, remove the coupler, and then store it in a locked vehicle or other location. If the coupler part isn't there no one will be able to come and steal your trailer when you're not around it. Another more traditional option would be using the Super...

  • Is There a Difference Between Ultra-Fab Wheel Stabilizers?
    Aside from price, the difference is that Ultra-Fab stabilizer # UF21-001090 is a single unit, while # UF21-001091 comes in a quantity of two. I've added links to review videos of each of these products for you to take a look at.

  • Preventing Theft of 5th Wheel Trailer Using Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter
    What I would do with the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5GX1216 is loosen the set screw that holds the inner coupler tube in, remove the coupler, and store it in a locked vehicle or other location. If the coupler part isn't there no one could come along and steal the trailer! Traditional gooseneck coupler locks won't work on this adapter so if you want to go with a more traditional method than what is described above I recommend the Super Grip chock # UF21-001090....
