Designed for tandem-axle trailers with up to 17" 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:
Specs:
Note: The purpose of the Super Grip Chocks XL is to limit front-to-back motion on parked tandem-axle trailers. Do not use as brakes or wheel wedges.
Eliminate the annoying rocking of your trailer or RV no matter where you park it. The Super Grip Chocks XL brace your tandem wheels against one another, stabilizing your trailer even on uneven terrain. No more front-to-back motion.
The pivoting louvers allow each Super Grip Chock XL 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 XLs are able to apply the force necessary between the tires to provide excellent stability for your trailer or RV.
The included E-Z ratchet makes it fast and easy to set up the Super Grip Chock XLs. Simply place a 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 one of the included padlocks.

Today, we're going to be taking a look at the Super Grip Chalk XL wheel stabilizer for tandem axle trailers and RVs. This product is from Ultrafab. The wheel chalk eliminates give between tandem axle tires to prevent rocking when your trailer or RV is parked. The chalk braces your tandem wheels against one another, which helps stabilize your trailer. Now, here, on the arms, we're going to have the pivoting louvers. Theres going to be 4, total, 2 on each side.
These are going to grip the tire tread, to prevent slipping. They pivot, that way they can fit the angle or the curvature of your tire, and they have the built in ridges, which is going to offer better grip against the tire tread. The units also going to include an easy ratchet. Thats going to make it very simple to expand and to retract the unit. Ill show you how to do that, here in a moment.
Its also lockable to deter theft. Its going to come with a padlock and its going to come with 3 keys that are keyed alike. The units going to feature an easy to access handle, here at the front. Makes it easy to transport the chalk to and from your storage area, and it makes it easy to install and remove the chalk from your application. Now, the units going to be made from a heavy gauge, steel construction. Its going to feature a corrosion resistant, zinc plating, so its going to be protected.
Its going to look good and last for a long time. This is available in a 1 pack or 2 pack. Its designed for dual axle trailers and RVs and its going to fit a wheel spacing anywhere from 3.5 all the way up to 17, so its a very versatile system. The units also covered with a lifetime warranty. Now, please keep in mind that the purpose of the chalk is to limit front to back motion, on parked, tandem axle trailers.
Be careful not to use this as a brake or a wheel wedge. When it comes to mounting the chalk, all you have to do is place it in the open position between the tandem tires of your trailer or RV, and use the ratchet to turn the head of the bolt on the threaded rod, until the width of the unit fits the spacing of your tires. Fit it in there. You can extend it out by hand to get it snugged up against the tires, and then once you get a somewhat tight fit, go ahead and finish the tightening process, with that included bracket. Makes it very easy to do, its got that threaded rod that runs all the way through the unit so that as you tighten this, its actually pushing the arms out, and thats going to create the nice, firm grip, between the tires, and its actually going to brace your tandem wheels against one another. Once you get that all the way tight, this bolt head would actually sit directly on top of this upper bracket, right here. Once thats flush on there, or seated on there, you can bring this cap around, and then you would take the included lock, move it to the open position, so youd place the key in there, open it up, place it through, and then lock it. With that locked, nobodys going to be able to open up that cap, which means nobodys going to be able to gain access to that bolt head and loosen up the unit, to remove from your particular setup. Its going to be fully secure. Thats going to do it for todays look at the Super Grip chalk XL wheel stabilizer, for tandem axle trailers and RVs.

Received my Super Grip Chock XL Wheel Stabilizers June 12 and put them to work that weekend. The product did as it stated on the product explanation. Our trailer did not rock back and fourth at all, just some side to side motion while we were getting in and out. They were a little bit of a pain to get adjusted at first after I received them. But after adjusting them and having them ready for the weekend maybe three minutes each to reinstall. I totally recommend these, make sure you keep your receipt, they have a life time warranty! 522994

What a difference. Used front and back side chocks as always but still had a little fore and aft rocking. Added these and wow! Steady as she stood. Agree that you will want the nut on the bottom to avoid the skirt. Locks provided will keep the opportunists at bay. Do not plan to stop anywhere I would be worried about anything worse. Great product and fits my wide spaced double axle. 310244
Still working great. Salty environment is not kind to them and recommend a good fresh water rinse and some spray silicone on the threaded rod, good to go.

This product has worked perfectly for me. About 20 campouts later and they stay on the camper all winter in storage and have work flawlessly. Makes me feel much more confident that the trailer will not roll anywhere and fit my wider stance axles perfectly 399134

Having purchased other items from ETrailer, This was the first place I looked for an answer for my wobbling RV Trailer when it is parked..... The descriptions and ideas are well placed, and after checking other websites for pricing, I definitely purchased from Etrailer.... Service, price and condition of delivered items were again impeccable!! 355243

I give it three stars, cause I not use them yet. But I would give etrailer a five star, this is my second time ordering from them.. both times package was on time just as they said it would and package was nicely packed.. I will continue to order from them. 482249

Product works great. Only thing wrong is the wrench that comes with it is cheap keeps slipping/ coming unlocked when using it. 387078

One the these x bracing chocks has already broken. I had to purchase another and it was twice as expensive. 451908
by: Paul H10/01/2016
First I have to comment on how quickly I received my packages from eTrailer. Excellent. Now for the review. I have used these just once so far on my Passport with the wider spaced axles. It works great!!! It really does. The locks they provide are a little generic and cheaply made. The keys are like those keys for locks kids play with. I'll end up buying some high quality locks if I want to lock these up. I didn't buy these for the lock so it doesn't bother me. Definitely worth it. I had to install mine with the screw pointing upwards. Makes sense once you have them. 302448

So far so good. They do their job and are easy to put on and take off. 568217

Exactly as described. Great price. Great communicatation. Super fast delivery. Would highly recommend! 434302
Working out just fine! Fit perfectly on our camper. We still feel some movement, but it helps. Think we could use a little more stabilization up front

Chocks work perfectly. They are easy to use and install and help stabilize my trailer. 489650
by: David P03/20/2018
Very happy with the performance, they add great stability to the RV. Only down side is the wrench should be of better quality. It starts to slip when you are close to being tight enough. 486889

Was as described. Prompt delivery. The box was flimsy and wide open when delivered. All was there but packages was very bad. 432430
it works as advertised but if I had to do it over again, I would have bought the better quality. Has more flex than the one I have for the other side.

Review from a similar Ultra-Fab Products Super Grip XL in Wheel Chocks
I received the Super Grip Chock Wheel Stabilizer today, exactly when promised. I greatly appreciate the timely service, as well as the follow up e-mail. As for the product, I could not be more pleased and impressed with the stabilizer, it's design, construction, and fit - A well thought out product. An additional impressive touch was the included ratchet tool and the security pad lock ! I would have gladly given the product a five star rating, but the packaging proved to be a major disappointment. When the package arrived, one end of the box was blown wide open. Fortunately, the stabilizer, ratchet, and the pad lock were still inside the plastic bag. In my opinion, the cardboard box is just too light for the weight of the product, to be able to endure multiple handlings during shipment across country. This product and it's original box needs to be boxed inside a stronger cardboard box for long distance shipping. An upgrade in shipping container is STRONGLY urged ! Thank you. 503170

Review from a similar Ultra-Fab Products Super Grip XL in Wheel Chocks
Within a month the screw are all thread stripped out it was made of cheap metal I would not recommend this item 360600
After a few times of you seen the super grip brake lock the all thread or bolt stripped out because it was made of cheap metal so I tried to fix it and put a different all thread in it, so its not the best product.
