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.

Video Transcript for Ultra-Fab Products Wheel Chocks - Wheel Chock - UF21-001091 Review

Today we're going to be taking a look at Part Number UF21-001091. These are the Ultra-Fab Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs. The wheel chocks are going to eliminate give between the tandem-axle tires to prevent rocking when parked. We're going to have the pivoting louvers on the arms. These are going to grip the tire tread to prevent slipping. They got a nice grip design and they rotate to conform to that particular area of the tire when you're tightening them in place.

That's going to include the E-Z ratchet. This is going to make it simple to expand the units. It's going to come with two padlocks. That way you can lock each one to help prevent theft of the trailer or the chocks, so it is lockable. Each one's going to have a nice, convenient carrying handle. That way it makes for easy transportation.

It makes for easy placement and easy removal. These are going to be made from a heavy-gauge steel construction with a corrosion resistant zinc plating so they're going to last a long time. They're going to stand up really well against rust and corrosion. Ultra-Fab's going to put a lifetime warranty on these products. With this part number, you're going to get two chocks. These are designed for dual-axle trailers and RVs with the wheel spacing ranging anywhere from 1" to 10-1/2".

With it fully compressed, you can see that we have a really narrow design right here in the center, so you can just take it, place it in between your tires, and then rotate it up. Then you can expand it to conform to your particular width in between your tires. Once you have it set, all you have to do is hand-tighten the tightening bolt. Once you get it snug in between your tires, to finish the tightening process, that's when you'd use the included ratchet. That's why that's provided.

These are going to conform to that particular area of the tire making sure that we get a nice grip. It's going to offer really great security, as well as stabilization. Now keep in mind the purpose of the Super Grip Chocks is to eliminate front-to-back motion on parked tandem-axle trailers. You do not want to use or rely on these as brakes or wheel wedges. Once you have it all the way tightened down, simply close the cover over the tightening bolt and then you can lock it. It's got a small hole right here. You place the padlock through, lock it in place, and that's going to help discourage theft of the trailer or wheel chock. That's going to do it for today's look at Part Number UF21-001091.

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. 310501

One year later, they still do what they are supposed to do. Thanks Ultra-Fab and ETrailer!

Just got these. I ordered them for my son to use on his trailer. So we won't know how good they actually work until spring when we can take it out. (That's why I only gave it a four star now). They are well built and will work great as I have a pair that I use on my trailer. 325539

They work great easy to install. 571921

by:

Only reason for 4 star instead of 5 is because like everyone else I feel that the wrench included is almost worthless. It is nice they include it but either include a better one and raise the price or remove it and lower the price so I can have more money to buy the ratchet wrench I am going to end up using. 433910


Comments

Ratchet is still working after a year, these chocks are a must have for dual axle trailers.

The stabilizers are just as described. They fit between the tires exactly they should. The shipping was incredibly fast! I was very pleased with how quickly it was received. Will use etrailer.com again for our camper needs. 323061

The chocks do a great job on stabilizing the trailer.

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. 496803

Im glad I purchased the chocks, the are where I had to set our 5th wheel has a 60 foot [] behind it.

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 465071

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. 423919


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.

Very happy with the fast service this is the 2nd we have ordered from them and we got the product faster then what they said it would be to us... that was nice would recommend this company... 364248

Initial impressions are that these are very solid, sturdy pieces of equipment. I installed them on my dual axle travel trailer and was happy with the stability they provided. I cannot comment on the long term durability at the moment but their construction indicates that they should last me a while. I docked them a star for two reasons, 1, the wrench that they provide with these things is a hunk of junk, and 2, the padlocks they provide are also a waste of material. The ratcheting mechanism in the wrench is prone to slippage even at low torques and I will be replacing it. The padlocks supplied don't work with the product. Simply put, the shackle is too short to reach through the padlock area and lock. Unless the equipment I received is an outlier be prepared to address these two areas. 396922

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. 430527

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

These are not built to last, the nut on the adjustment screw is not hardened. The threads inside the nut bend and cause the screw to get jammed 716845



- UF21-001091
by:

So much simpler than messing around with traditional wedge chocks, and they hold tighter in my opinion. Any slight reduction in movement at the tires makes a big difference throughout the rest of the trailer 707372

These Chocks definitely keep the wheels from moving. Forgot to remove them one time before moving the trailer and it wouldn't budge. However they don't do as good a job of removing the sway when you are in the trailer as advertised. They do seem to remove some but not all of the front to back motion. 686886

These work as advertised. The only reason I did not give 5 stars is that the two locks provided had 3 sets of keys each specifically cut for that lock, multiplying the number of keys to keep track of. 584448
