This review will only be helpful for those who are looking for a fantastic solution for a utility trailer. My 2019 Lamar, 14' long with 2' dovetail and 32" ramp gate utility trailer connected to my 2018 F-150 I bought new in February could not clear my mother's steep driveway without using long 2" x 6' boards for the wheels of the trailer which were a pain to carry around and a lot of unnecessary work. Finding these casters were the answer to my problem as the attached photos will prove. I did have to spend an additional money to make them work (2 - 4" PVC drains for the top ([Local hardware store]), 8 - 6" x 3/8 grade 8 bolts and 2 - 1/8" thick washers from [Local hardware store] and I cut two pieces off a 2 x 4 - 4" long each. Yesterday I loaded the trailer with about 1000 lbs. and the casters worked perfectly! I'm storing the trailer in my mother's garage while I'm moving her out of her house so I needed the casters for storing and moving. I'll add more photos when the trailer is completely loaded so you can see for yourself. I'm hoping the search engines pick up the keywords in this review so others in my position can find a solution that works and is worth every penny spent. Every other set of casters I looked for in the usual places look so inferior and I believe would crumble under the weight. These casters held the trailer with 1000 lbs on it like it was nothing. Fantastic quality in a great package and they don't swivel which was important for my application. Even if this review only helps one person it was worth writing (hopefully it helps many more)!



After a year I can say that these wheels are still worth every penny! Sometimes I forget theyre even installed until someone says how can you back up your trailer when all four tires are off the ground?. I understand that my application is NOT what these were designed for but as I stated a year ago if this helps even one person it was worth the time to write a review.


I bought these for my Cougar 29RLI and they disintegrated the first time I used them. I did use the bearings & sleeves and made my own wheels out of 4140 steel with Delrin on the outside diameter. after 5 trips no failure.


I received the skid wheels in a timely manner. Installation was simple and trouble free, the skid wheels are as advertised. I have a steep, downhill driveway that flattens out to a parking area. The hitch on my motorhome will scrape every time if I don't use some sort of portable blocking or ramp to roll over and lift the rear end. Now with the skid wheels installed, I just back down the driveway and into my parking area. No scraping on the concrete, it just rolls right into place. Problem solved!


Not that thrilled with this kit.
construction seems well suited to the task
No instructions - not a major deal breaker but always a nice touch
Bolts were too long and threading too short - I had to buy some lockwashers to add to the height
Too sloppy so I cut some wood to fill most of the gap plus it helped square it up.
Overall, it looks like it will do the job but spent WAY too much time installing this kit


I purchased these wheels with the hope of assisting my 24' RV to make it up my pretty steep driveway. Before the wheels, my trailer hitch would bottom out and be digging into the asphalt of the street just as I was starting to go up my driveway. Now with the wheels, I'm able to get the lift of the hitch I need to make it up. I can now park in my driveway and off the street. Very happy with them so far!


Great experience from checkout to installation. They quickly provided me with shipping and tracking info. Package was double boxed and arrived on time as promised.

Ended up using item: UF48-979015 on a boat trailer and not an RV. Should do the trick!

Would purchase again.


Zerk fitting broke off before I got the Class C out the driveway!! Will have to easy-out and replace the fitting. Otherwise, installation was easy. It performs really well on my 28ft RV.


These skid wheels worked perfect on my 19 foot boat trailer. I no longer have to worry about only having 1/2 inch clearance coming down private road to public srreet. Placed they hit pavement and keep back end from dragging, no more carrying replacement tail lights for me....... thank god!
Highly recommend these wheeled, easy to install and seem to work well.



A year later and still going strong. Show almost no signs of being deagged 5 to10 feet on pavement amd concrete basically 2 times a week as we leave drive. They are great product. Love the fact i dont have to touch up trailer paint monthly now and havent scraped a trailer light since install.


The install was easy. The idea was good but my fifth wheel was too heavy for these. I needed them due to my driveway being sloped and rear of fifth wheel would drag when I backed in or pulled out. Went on first trip and when I arrived at camp site found the wheels were ground away. Only thing left were the mounts and the little axles. First trip destroyed them. My fifth wheel is a 43 foot Jayco dual axle with a factory installed trailer hitch in the rear.

These particular skid wheels work best for RVs 30 feet in length or shorter. For a longer fifth wheel such as yours, Id recommend going with steel wheels such as whats used with part # UF48-979017. This item would mount to the crossbar of your hitch, and would fit crossbars up to 2-12 inches square.


The order arrived quickly, went on the trailer easily.
After 1 year they are holding up well!


Just received my Ultra- fab skid wheels. I was unable to grease the bearings because the fittings are too close to the wheel flange preventing the grease gun nozzle from connecting properly. I cut a radius in the wheel flange and was then able to connect the gun.
I find it hard to believe that this product could have gone thru any inspection process - which is probably typical of many products from a certain country.

I did reach out to the manufacturer who agreed that it is a tight fit and if the grease fitting is not perfectly placed in the wheel then it will be difficult to use the grease gun. You can doing a little grinding to make room for the grease gun.


Product was just what I expected it to be. Works great on my low profile/drop axle trailer, keeping the tail from dragging when backing into my driveway.

George N.


Great product, well built, holding up very well after one year of use.


Well I put them on and they worked like they were supposed to. They only had to roll 10 feet. the 2nd time out, the internal structure that holds the outer wheel to the hub, completely broke away, leaving the outer wheel free floating. So a complete fail in my book. I had to take them off and ship them back. The things are not light so that cost was high. then I had to wait like 4 weeks to get a new set. I have not put on the new set yet, but I hope this was a one time product flaw. Time will tell.

Etrailer Expert

I also hope your warranty replacement will work out better for you. Keep in mind that these skid wheels are not designed for use on motorhomes over 30 feet long or on diesel-pusher motorhomes due to the extra force that would be put on the wheels.


I have had the skid wheels on my 25 foot Class C motor home for about one year now. My driveway has a very steep incline and the rear end of my rig would scrap along the driveway as I backed up. I purchased and installed the skid wheels to avoid the rear of my rig from scraping the asphalt. They worked as intended. However, a few months after installing them one of them broke (it may have been my fault). The wheel detached from the brace and now floats freely. I continued to use the broken skid wheel along with the one that did not break. Even broken, it stops the rig from scraping the driveway. I would have given four stars had it not broken.


After not even a year one skid wheel broke. Evidently the hub is the weak link. Called etrailer to see if there was any warranty or something they could do about it and was told NO. I had to buy a complete new set just to replace one wheel. All I needed was the wheel, the bracket was still good. We will see how long the new one will last.


I recommend these skid wheels. They have been in use for a year now and have held up well. The trailer is used about every three weeks and so the wheels contact concrete twice for each use. That totals about 35 times in the last year.


Problem is that the wheels will break when they get a little sideways motion when your RV bottoms out and you are turning the steering wheels. Looks like the wheels with swivals are needed


Used them for back bumper, anti skid for 5th wheel trailer. They work great for saving bumper on shallow depressions.


These skid wheels seem to be a solid product and I am confident they will do the job. Frankly it would be fine with me if they never hit the ground but they seem good insurance in case. Mounting was easy, I am a good mechanic. They do measure 4.75” from the bottom of the hitch which should work for my rig.


The skid wheels look pretty strong. Well built and I feel confident they will save the rear end of my 5th wheel from getting scraped up. My 5th wheel has 2 scrapes previous to installing the skid wheels but not any more.


Great idea, but we have already had one customer return with broken wheel. The wheel is under warranty, but not the labor and shipping.
Many companies now offer the option of sending a picture of the damaged product and just replacing that one part...


So thankful for this product! No more scraping the driveway! We just ease out onto the road and GO!


Did not really get a chance to use them since they did not fit my RV however, they were very solid and all the hardware appeared to be heavy duty.
Customer service was exceptional. Excellent communication.


Having received the rollers friday night, I planned to install them yesterday. I figured an hour at the most. Wrong. I had to drive 15 miles back home to make up spacers because the bolts are too long. Two hours later I had them installed. Have no idea if they work. Will find out this week.


The wheels do what they were intended to do. Very heavy duty, very expensive.
Some of the holes didn't align and had to be forced but the wheels still rolled freely.

  • Skid Wheel Recommendation for a Camper Bumper that is 4 inch by 4 inch
    I went out into our warehouse and pulled a set of the Ultra-Fab Rotating, Hitch Mounted Skid Wheels # UF48-979014 and found that the distance from the bottom of the wheel to where the bottom plate will be is 5-3/4 inches. Since the bumper you plan to install the skid wheels on is 4 inch by 4 inch you will need to go with a weld on set of skid wheels like the # UF48-979023 or # UF48-979021 or the bolt-on type # UF48-979015 that includes 4-3/4-inch-long mounting bolts.

  • Skid Wheel Recommendation for Dual Axle Trailer that Drags Pulling in Driveway
    I really wish we had an air suspension kit that would do what you are looking for, but we only have skid wheels like the part # UF48-979015 which would help with the dragging instead.

  • Best Choice of Skid Wheels for Trailer With 4-Inch Hitch Tube
    If your trailer's 4-inch hitch tube is too large for a bracket-mount type skid wheel like Ultra-Fab # UF48-979017 then you can use one of the weld-on types like # UF48-979023 or # UF48-979021 or the bolt-on type # UF48-979015 that includes 4-3/4-inch-long mounting bolts. Swivel-type skid wheels such as # UF48-979012 will not cause the trailer to swing since they will be engaging the ground only very briefly.

  • Bolt-On Skid Wheels For A 5th Wheel Trailer That Works With A 3-1/2" Square Hitch Bar
    For your fifth wheel we do have an option for you, but we don't have an option that swivels. The Ultra-Fab Hitch Mounted Skid Wheels for RVs up to 30' Long # UF48-979015 will work great for your fifth wheel and will fit over a 3-1/2" wide square hitch cross tube. Skid wheels aren't designed to be bolted to the bumper of your 5th wheel because the bumper isn't going to be able to handle the type of force applied to the skid wheel when your 5th wheel bottoms out.

Their overall length is 5-1/4-inches and their length from the bottom of the head to the end of the threads is indeed 5-inches. Bolt diameter is 1/4-inch.

    Skid wheels are not designed to be attached the to bumper. The are intended to be installed on the frame or the hitch. Generally, the bumper isn't capable of handling the force applied by the skid wheels when they bottom-out. For your 5th wheel trailer, I recommend the Ultra-Fab Skid Wheels # UF48-979012.

  • Do the Ultra-Fab Hitch Mounted Skid Wheels # UF48-979015 Have any Type of Capacity
    Rollers like the Ultra-Fab Hitch Mounted Skid Wheels # UF48-979015 don't have specific weight limits since it would be hard to determine exactly how much weight would be on the rollers at any given time when they are use. Instead, they are limited by the size of the RVs they are used on. The # UF48-979015 that you referenced is designed to work well on low profile RVs that are up to 30 feet in length. The diameter of the bolt that runs through the roller is 3/8 of an inch.

  • How do Ultra-Fab Skid Wheels Attach to 30 Foot 2020 Airstream Trailer
    There are bolt-on skid wheels, though the bolt-on options all require being mounted to a hitch, such as the Ultra-Fab Hitch Mounted Skid Wheels for RVs up to 30' Long # UF48-979015. So you could use those of your Airstream has a trailer hitch with an exposed square crossbar, otherwise each of the skid wheels do need to have their brackets welded on.

  • Skid Wheel Compatibility with Boat Trailer
    The Ultra-Fab Hitch Mounted Skid Wheels for RVs up to 30' Long - 4" Diameter - Qty 2 # UF48-979015 can absolutely be mounted on the back of a boat trailer. The biggest consideration is the boat trailer frame material because if you have an aluminum frame you will want to make sure to add a layer of rubber protection because the steel hardware does not play well with aluminum and can cause galvanic corrosion due to the dissimilar metals if there isn't a protective layer between them.

  • Recommended Ultra-Fab Skid Wheel on a 4 Inch by 4 Inch Bumper
    I would instead recommend the Ultra-Fab # UF48-979011 skid wheel for your 4 inch by 4 inch bumper. The plate would need to be welded to the frame and then the included mounting hardware be used to secure the skid wheel. The Ultra-Fab Skid Wheels # UF48-979015 mounting hardware would be at the 4 inch distance and unsuitable for your bumper.

  • Recommendations of Skid Wheels for 20 Ft. Food Trailer
    That is heavily dependent on the mounting points available for your 20 Ft. food trailer. But I prefer the Ultra-Fab Rotating Skid Wheels, # UF48-979014. These will clamp onto square crossbar locations to help prevent tail dragging and have wheels that rotate for full range of motion. I prefer the ability to bolt in place as opposed to needing to weld. The Ultra-Fab, # UF48-979015 is a similar wheel without the rotating feature. However, if you do not have suitable location to use the...

  • Recommended Skid Wheel For Boat Trailer with Cross Member 2" Wide and 4" Tall
    You might be able to use longer U-bolts with the # UF48-979017 but I recommend instead using the Ultra-Fab Hitch Mounted Skid Wheels for RVs up to 30' Long - 4" Diameter - Qty 2 # UF48-979015 since the bolts have a usable length of 5" so they'll fit on the 4" tall crossmember. It's essentially the same part but just installs a bit different. The wheel is 4" diameter, so it should work fine with 6-1/2" clearance. I've linked a review video of these that I recommend having a look at.

  • Skid Wheels Compatible with 35 Foot Long RV
    The Ultra-Fab Hitch Mounted Skid Wheels for RVs up to 30' Long - 4" Diameter - Qty 2 # UF48-979015 is not suitable according to the manufacturer. I recommend the Roadmaster Rollaway Trailer Hitch Protector # RM-050 as an option for your trailer hitch receiver. The Ultra-Fab Skid Wheels for Class A RVs 34' and Longer - 6" Diameter - Qty 2 # UF48-979013 are the best option for your RV so I recommend going that route eventually when you can find someone to weld the plates for you.

  • Are Ultra-Fab Skid Wheels Replaceable

    Skid wheels, like the Ultra-Fab # UF48-979015 that you referenced, do not have a weight capacity as they are not really meant to bear weight. As long as you do not have an RV over 30' long and you have installed these skid wheels properly you shouldn't have a problem with the weight of the back of your trailer (which is somewhat minimal) on these wheels or any skiw wheels.

  • Recommended Skid Wheels For 36 Foot Tuscany Motorhome
    The longer the RV, and the greater the distance between the rear of the RV and the back axle, the greater the forces the skid wheels will have to deal with. This is why the larger, stronger skid wheel those used on the Ultra-Fab # UF48-979013 are recommended for RVs greater than 34 feet in length. The smaller # UF48-979015 would probably work, but you would get more life out of the larger skid wheels I recommended.

  • Skid Wheel Recommendation that Won't Damage Black Top Driveway for a 23 Foot RV
    To avoid scraping up your driveway I recommend going with the urethane wheels such as # UF48-979014 or # UF48-979015 because they are much less likely to damage the driveway compared to steel rollers. The steel rollers you mentioned are all basically the same with the exception of the sizes of each. But they are a little more low profile so they would not make contact with the ground as soon as the urethane coated wheels.

  • Can Skid Wheels be Mounted to Bumper on RV
    You will want to avoid installing the Ultra-Fab Hitch Mounted Skid Wheels for RVs # UF48-979015 on your bumper as your bumper will not be able to resist the weight of your RV since it is not structural. I recommend installing the Ultra-Fab Skid Wheels for Low-Profile RVs # UF48-979011 instead. These can be installed on either your RV's frame or a frame-mounted trailer hitch receiver. You will need to have the brackets welded on before bolting the skid wheels to them.
