Video Transcript for Stromberg Carlson Chock Wheel Stabilizers Review

What's up everybody It's AJ with Today we're gonna be checking out the Stromberg Carlson Wheel Stabilizer. Now what this is gonna do, is you can wedge that in between your tires, and it's gonna push out as you use the wrench to let it expand. It's gonna push on those tires, really limiting that front to back movement. So it's gonna work in tandem with the other objects on your camper, just to help stabilize everything when you're on the inside or the kiddos are running around on the inside. Just keep that front to back movement to a very minimum, if not at all.

Let's check it out. Something I want to point out right away though, is it is not meant to be used as a wheel chock. We suggest still using your existing wheel chocks just to keep the trailer in place. This is more meant for stabilization. Now it's time to put it to the test.

Now these are meant to be used in combination with the existing scissor lifts. So during the test, you're gonna make sure the lifts or stabilizers are down and in place. And now I'm gonna go inside and kind of walk around and see how much movement we get without these installed. All right, now that I'm inside the camper, I'm just kinda gonna walk around a little bit. Go from side to side.

And just go up here into the kitchen and walk around. There's definitely a little bit of movement, but not a whole lot. Seems like the stabilizer's working pretty good, but if I make some aggressive movements side to side, not a big deal. Front to back though, you can definitely feel it rolling a little bit forward and backwards, forward and backwards. So now I'm gonna walk around just a little bit in here, and just the normal walk around movement.

Not too much, just a little bit, I guess, I feel as I'm walking around. There's not so much side to side. That really, the front stabilizer is helping with that. I think it's the front to back movement is what we're gonna feel. So I kind of do an aggressive forward and backwards. You can definitely feel it going forward and back. You can see the blinds too, moving. So I am getting it to rock, but that's just being aggressive, being do it this way. So when I was inside moving it back and forth, you saw a lot of movement, probably close to the treads. You can see them going back and forth. A lot of tires kind of rolling forward and back. And that's exactly why we're gonna install this, to try and eliminate that. So what you do to install it, you just pick it up by the handle. Watch out because there are pinch points. So as it goes to expand or retract, you don't want your hand in the wrong spot. So you got this nice big handle with the warnings on there on where to put your hands. So we'll put it in there. You want to get it far enough in so it's making contact with the tire on all four points. So you kind of see if I do it wrong, let me try and do it wrong real quick. It's not really touching here at the bottom. So when you go to tighten it or expand it, it's not gonna hit all the same time. Then as we go in a little bit further, you can kind of feel it as you go up or down. Kind of find that sweet spot where it's gonna make contact on all the tires. Looks like we're right about there. Then come back with the included tool, and kind of can sit in there by itself because of the ratchet. You just put that on there, and make sure it's going the right way though. There you go. Once you get it right, it'll ratchet it as it slowly pushes out into the tire. Just keep an eye on it having it be too aggressive. You just want it to make contact on all four, and see it push just a little bit. I think we're about there. It's nice and in place. With the stabilizers in place, let's give it a test. I'm gonna walk around a little bit more this time. Again, I didn't feel a whole lot last time I was walking back and forth, but this is just kind of a test. Not really getting much out of it. So I'm not feeling anything. So let's try that aggressive test again, going forward and back. Not really getting a whole lot of movement. It really helped out. If you look at the blinds once more, there's a little bit of movement, but not as much as there was last time. And I'm doing the exact same thing. Hopefully you saw how well it worked, 'cause I could definitely feel it when I was going back and forth. I always like in the videos when we're doing something like this and it actually works as good as it's supposed to. 'Cause this really did. The best I can explain to you was the blinds. You can see the blinds move aggressively without that in place. With it in place, they barely moved. That's how it felt while I was doing it on the inside. But it's not doing it alone. Like we said earlier, it works in combination with other things underneath your camper, like your scissor lifts. We even have a MORryde cross brace system here installed. And that really helped with the side to side. But remember how I kept saying, side to side doesn't matter as much in here because of that cross brace doing its job. But that in combination with that made sure that there was barely any movement on the inside when I was walking around and even aggressively trying to get it to move. Now there is different versions of these wheel stabilizers out there from different manufacturers. They are a lot alike. Most of them have the same features. Almost all of them do of tighten them up here, the feet, and the contact points on the tires and how it pushes out. The one big difference for all of them though, is do they lock or not lock So the one we have here does not lock. Now there's an Ultra-Fab one that does lock. And how that works is you put a padlock up here where the cap comes up, and that is where you put your padlock and lock it up tight. And that's just helpful. Let's say you're leaving out in a parking spot for winter. You can lock it up. And it's just one more thing to keep people from messing with it when you're not around. They're gonna see that lock and just go on to the next one that doesn't have a lock most likely, and it just keeps your stuff in place. It's gonna be constructed of steel with a rust resistant coating. So you don't have to worry about the elements bothering you as fast. But we know as coatings work, they can start to peel off or come off over time. So just be mindful of that. Another thing would be they work with tire spacings from two inches all the way up to 17 inches. So keep that in mind with your tire spacing. Make sure you measure that before you order one of these, and make sure it's gonna work with your rig. And come with their own ratcheting tool, which I really liked that part. They could have easily not done this. So you'd have to have your own tools and use for it. I like that it's got a specific tool and you just have this whenever you need it. So you can put this in the basement door, put it in the toolbox. You know exactly what it's for. It's to set this up. Overall, I think it does its job really well. I think we showed that too. I could feel it while I was on the inside. You saw the movement difference of this being installed and working with everything else on your camper, just to keep it nice and level and keep that movement down when you're walking around, so you can enjoy your time. Well, thanks for hanging out and I hope this helped..

Rid your rig of the rocking with these easy-to-use, stabilizing wheel chocks for dual-axle trailers and motorhomes. Simply place a chock between tandem tires and expand it until the give between the wheels is gone. Expands up to 17" wide.


We have a 36' travel trailer with spread axles. These work great in addition to the stabilizers to stop the rocking movement of the trailer.


Folks at etrailer have always been helpful. First shipment was lost by UPS 10 miles from my house. Problem is the box it's shipped in came apart and address was lost. etrailer was on top of it and shipped another unit which I received no problem. Using Leveling distribution hitch next week.


Well built and easy to use. Back and forth rocking motion has been eliminated. I'm kicking myself for not buying wheel stabilizers years ago.


If you carry what I need, that’s where i’ll purchase it. Great product quality, good price and super fast shipping!! A+


We put them on for our long term stays, they work well to stabilize our rig.


They never would really expand against the tire like they are supposed to. also, one of them the bearings have started to fall out. They are not worth using.


I ordered the wheel chokes on 1/10 and they arrived on 1/13, I put them on today (/14) and they work great, trailer does not move when walking in it. What I paid for a pair of them (including freight and tax) is what my local RV dealer sells one for. You will not be disappointed!!!


They work exactly as advertised and easy to use


They work great for the 14 inch spread I have


Work great, stabilize camper as well


I haven't I stalled as of yet but when I do I'll let you know, however Roger was very helpful and professional, enjoyed chatting with him looking forward to doing future business


Great product!! Does what it is expected to do well!!


Great fast service every time I've ordered RV parts.


Made our 5th wheel more steady in the back. High quality product


Great product, great fit


I have not use this product yet, but it looks like it is well made. Ordered this product at 11:30 am, arrived at 8:30am the next day by UPS. Very good service.


Should help to stop some rocking! Seem great, but I haven't put them to the test yet.

  • Chock Wheel Stabilizers with a Wide Range of Fitment
    I have a potential solution for you, but we have never carried the Epoartist ST20RVA wheel chock stabilizers. From what I was able to find on the Epoartist ST20RVA wheel chock stabilizers they extend between 3"-12". We have the Stromberg Carlson Chock Wheel Stabilizers # SC47MR available which fit wheel spacing between 2"-17". This offers another inch smaller and an additional 5" wider. You would just want to measure between your wheels to verify fitment.

    The FasTen RV Leveling Blocks w/ Carrying Handle # CAM44512 can definitely be used to help jack up your travel trailer and then you can use the Stromberg Carlson Chock Wheel Stabilizers # SC47MR as chocks between the wheels to keep them stable just like standard chocks would.

  • Highest Capacity Scissor Style Stabilizer Jacks For a 2012 Artic Fox 25R Travel Trailer
    The Ultra-Fab Ultra Scissor Jacks # UF48-979002 do have the highest capacity of the scissor style stabilizer jacks we carry at 6,500lbs per jack. This capacity is support capacity and does not have any lift rating. I would recommend using the Stromberg Carlson Chock Wheel Stabilizers # SC47MR since you are on such a slope. These will reduce the amount the trailer creeps down the hill.
