Well, I haven't had any adventures with the wheels installed yet, but I successfully pulled out of and back into my driveway with nothing broken this time. The wheels saved me and I saw the trailer wheel on the driver side come off the ground some as I pulled out, so I know these skid wheels are well made.

After one year, I had one wheel break and etrailer was super helpful to get it replaced under warranty. The only area that I have really needed this for is my driveway and it has worked out perfectly.


i recently purchased these "skid wheels" for my 2023 wolfpup and they worked perfectly, installation was easy enough, all i had to do was drill the proper 3/8" hole and wham bam thank you, they installed with what was provided. If you want to, you could install these with "u bolts" (not provided). after installation, i pulled the trailer out of the driveway and they worked perfectly. remember, measure twice and follow the directions provided, mark you location and measure again to make sure they are located properly. Like i said, they worked great for me.


Thank you Gwen for answering my questions about these skid wheels. Can't wait to get them mounted!



My skid wheels were mounted to a 16 enclosed trailer that I use to haul an antique car or my antique motorcycles. We have a very steep driveway and these skid wheels work really good to keep the tail end from dragging. Ive also noticed them preventing the tail end of the trailer from dragging in certain situations. They work great and I would definitely buy them again.


Wheels are not as strong as they seem to be, they need to be made of solid steel not pot metal ( metal poured into a mold.)
This is my second set. One has broken after 1 1/2 years of service.



They are great, make sure to grease the wheel bearings regularly, and check the wheels that they spin freely especially in wet conditions

@Scott Outstanding advice, thank you!


Excellent product. Work just as described. I installed them on my 40’ travel trailer (12,000LB GVWR). The mounting plates are welded directly to the frame and the skid wheels are affixed to the plate with the supplied bolts.


Grabbed these about a year ago, working great!!!

A bit of welding and drilling, but I’m sure each trailer is different. Would buy again, but something tells me I won’t have to!!!


These wheels are much better than ordinary casters from a hardware store. They are very heavy duty and perfect for a trailer. We have a Lance 1575 that is low to the ground, plus we have a steep driveway. The trailer's skid bars drug very badly while entering or exiting our driveway and these wheels solved the problem. Our trailer doesn't have the typical square bumper, which would have made mounting these wheels much easier, and its frame is pretty light weight. I ended up getting some 2 inch angle iron and "sandwiched" the trailer undercarriage to make a way to bolt on the wheels so that they are centered directly under the frame. That has worked fine. We can now move our trailer in and out very quietly.


I like it but there was no hardware included. Now I'm going have to go find hardware I need. Got the wheels and plates but no bolts and washers.i thought those would be included.

No, you are correct as the bolts and washers are included. I will have our Customer Service team reach out to you.


They keep breaking

I am sorry to hear that this item is not working. We will need some more information in order for us to better assist you. I have sent your information over to our customer service department for them to get in touch with you. Once you have a solution, we would appreciate your updated feedback of your experience and the product.


Excellent design and construction. Went together very easily, and exactly what I needed. Grease fittings are a plus on both the wheel and caster. Will make it very durable.


Product received yesterday and I must say that it is very beefy. Heavy Duty. I will be installing this in a couple days and look forward to being able to drive my Travel Trailer into my driveway without chewing up my Stabilizer Jacks. One suggestion for eTrailer is that they double box when shipping. My set came in the original product box. Because of the weight of the rollers the box had split open on one side. One of the mounting plates was sticking half way out of the box. All parts were accounted for.



So glad I purchased these a year ago.


These wheels worked perfectly to protect my sewer dump pipe from dragging for my lance trailer 1575 2015 model, the stock skid guards are worthless, I recommend replacing them with these wheels and brackets, all bracket holes match up with the lance trailer frame and is a snap to install less then 15min



After a year and using our trailer on 13 trips, the skid wheels have no damage and work very well saving our dump sewer pips. The wheels have two grease points wheel and swivel they fit perfectly on our lance 1575 trailer


My Ultra-Fab 4" travel trailer skid wheels arrived today. Packaging was intact and solidly wrapped. Etrailer is a great company for your rv supplies.



Doing what they are supposed to do. No more dragging. I go very slow in situations of a potential drag and watch wheels make cpntact and roll. Holding up well so far.


Ultra-Fab is the only company I've found to produce skid wheels of the size and composition needed. I have a class B Van and a somewhat steep driveway The problem is that the metal castings for the wheels fail. Over the past several years I've gone through 3 of these wheels, with hub failure being the problem. If someone made a pressed steel hub with the 'Ultra-Fab tire' instead of a casting, the wheels would probably last longer, but so far, I've not found any. Solid steel skid wheels work just fine but tear up the street.


Have a Winnabago 24J RV and the skid wheels come in handy on a lot of steep entrances, like gas stations. Works well when hauling bikes on my rear hitch. Gives the bikes more pavement clearance in the event of contact. Have had for over a year and still look and act like new.


I added these to my 2018 42' Montana 5th Wheel camper and they have worked perfectly. I have 1 low spot that they come in contact with my drive way. I would recommend these if you have a light contact like me. I don't think these would hold up if it was a harder or heavier contact with the road. But for my purpose they are perfect.


Product shattered under the weight of the trailer.


Well, turns out I intended to write this review much earlier and thanks for the reminder.

Yes, this set of skid wheels work PERFECTLY!!! I could not be happier. We take our trailer to the mountains and it has come in quite handy on our very sloped driveway to the street---after all, it is in the mountains. Very happy with the purchase.


Excellent so far


Very happy with the product. I have read the directions thoroughly and they were adequate for the product. Haven't dragged them on the ground yet but the quality appears to be good. I had an issue with damage during shipping- a zerk fitting broke off the swivel bearings on one caster and the zerk on the other caster is slightly deformed. A little more packing material would have prevented this. I'm picking up a couple at the store today to put in before I install.


I went through two sets of these in a matter of a few weeks. I finally got a set a set of the 3" steel wheels which fit into the brackets for these wheels and they are still going strong


Both wheels broke the third time taking the trailer out of our drive way. The metal parts, inner part, around the axels broke into several pieces.

The first two times they worked great and I was very happy.

We have purchased a second set but have not used them yet.


Worked out better than I imagined. I could not get my 34 ft Keystone Sprinter in my driveway without scraping the bumper and destroying the back Jack's. Problem solved. There are even 2 campgrounds I could not go to due to steep entries now there is no problem.


they keep the back of my camber trailer from dragging on my driveway that has a dip in the driveway. Thanks for a great product.



Not good, 1 broke when backing up driveway


Broke the first time I pulled out of my driveway in my 20' enclosed trailer hauling 5 dirtbikes

  • Skid Wheels for 24 Foot Box Trailer
    For your 24 foot box trailer I recommend using the Ultra-Fab Skid Wheels # UF48-979011. These wheels have brackets which you weld to your RV; you would then bolt the skid wheels to the brackets with the hardware that comes with the kit. These wheels are 4" in diameter and have 1/4" urethane layers on the outer edge. I've added a link to a video review of these wheels for you to check out as well.

  • What are the Overall Dimensions of the Mounting Plate in Ultra-Fab Skid Wheels # UF48-979011
    I went out to the warehouse and pulled an Ultra-Fab Skid Wheels, # UF48-979011, to measure that plate for you. The length is just under 7 inches and the height or width is 4 inches. The plate is approximately 3/16 of an inch thick.

  • What Size Installation Bolts are Included with the Ultra-Fab Skid Wheels for Low-Profile RVs
    I spoke to my contact at Ultra-Fab and he informed me that Ultra-Fab Skid Wheels # UF48-979011 that you referenced comes with a plate and installation hardware and there are two sizes of bolts that are included. The smaller bolts are 1-1/4 inches long with a 9/16 inch head and the larger bolts are 1-1/2 inches long with a 3/4 inch head. He said that typically when you install this you weld the plate to the vehicle frame and then use the included bolts to attach the caster to the plate.

  • Overall Height of the 4 Inch and 6 Inch Ultra-Fab Class A Skid Wheels
    The distance from the top of the mounting plate to the bottom of the wheel on the Ultra-Fab 4 Inch Skid Wheels, # UF48-979011, is 5-3/4 inches and for the 6 Inch wheels, # UF48-979013, 7-3/4 inches. I have attached a photo for you showing these measurements.

  • Recommended Location to Install Skid Wheels on RV with 5-Inch Square bumper
    Generally an RV bumper is designed to take lateral force but not the vertical force it would encounter from having skid wheels installed on it. The RV frame at the rear (near the bumper) is the best place to mount skid wheels. If there is a hitch on the RV that too can be used as a mounting point. The plate included in Ultra-Fab skid wheel kit # UF48-979011 is what the skid wheel itself attaches to after the plate is welded on, and you are correct that the bolt heads do sit on the top...

  • Skid Wheel Recommendation for 18 Foot Jayco Trailer to Prevent Skidding on Driveway
    For your 18 foot trailer I really like the frame mount skid wheels that can swivel. For that the Ultra Fab kit part # UF48-979011 that you referenced would be your best option. I attached a picture that shows these attached to a trailer frame as well. These don't have weight capacities, but instead have trailer length recommendations. This kit is designed for up to 30 foot trailer so based on that this would be what you need.

  • Skid Wheel Recommendations for a 24 Enclosed Trailer
    I'd recommend the # UF48-979011 skid wheels from Ultra-Fab that you've already looked at, which is what we'd recommend for a trailer or RV 30 feet long or less. Ideally, you'd want to mount the wheels to something substantial as far rearward on the underside of the trailer as possible. You can see product description video of the skid wheels by clicking the provided link. I've also linked you to the installation instructions.

  • Skid Wheel Recommendation for a 2017 Coachmen Apex 215RBK
    I did a little research on your 2017 Coachmen Apex trailer Model 215RBK and found that it is 25 feet, 4 inches long overall so skid wheels # UF48-979011 are a great option for you. These particular skid wheels are a weld-on application so installation should be performed by a professional welder. I would stay with the 4 inch diameter wheels in order to keep the reduction to ground clearance at a minimum. I have linked a video review of these skids wheels for you.

  • Mounting Hole Pattern of the Wheel Assembly in Skid Wheel Set # UF48-979011
    The holes on the wheel bracket itself are spaced 3-3/8 inches apart on center by 2-1/2 inches apart on center. You can use those dimensions to determine if they match up to the holes you have. I have also included a link to our skid wheel selection. You mind find something in there that will work better for your application.

  • How Do # UF48-979011 Skid Wheels Attach to RV and Do They Reduce Ground Clearance
    The skid wheels would typically weld to the underside of the RV frame. Using skid wheels would be advantageous because it would help prevent the RV undercarriage from scraping against obstructions like speed bumps. Instead, the wheel would hit the obstruction and ride along it. So technically, the wheels would decrease ground clearance but it would not create a problem because the wheels would pass over the obstacle.

    Adding skid wheels to your open car trailer is indeed what I recommend to help prevent the trailer from dragging when going up a steep driveway.

However, if you check out the install instructions link I attached there are instructions on how to use U-bolts to install this kit are included. The U-bolts would need to be 2-3/4 inches wide.

  • Skid Wheel Recommendation for 27 Foot Travel Trailer
    I do have a solution for you but the Ultra-Fab Skid Wheels # UF48-979014 you referenced will not work because they install on an existing 2-1/2" x 2-1/2" square hitch tube on a motorhome. For your 27 foot travel trailer I recommend going with the Ultra-Fab Skid Wheels for Low-Profile RV's # UF48-979011. These are specifically designed for travel trailers up to 30 feet long and install on the frame like you want to do. The # UF48-979011 does require the included brackets to be welded to...

  • Recommended Diameter Skid Wheel for Rear of 31 Foot 8 Inch Motorhome.
    For motorhomes longer than 30 feet, Ultra-Fab highly recommends using the 5 inch skid wheels, part # UF48-979012. The reason is that the longer motorhomes usually have a longer overhang at the rear. Using a shorter wheel like the 4 inch diameter would increase your chances of dragging and damaging something when backing up. The 5 inch diameter wheel would offer you more protection, so I'd recommend going that route.

  • Ultra Fab Skid Wheel Recommendation for a 32 Foot Long Heartland Mallard M29
    For your length of RV the recommended skid wheels are actually the # UF48-979012 as this kit is good for up to 34 feet. This would work well for you and would be what we recommend. The part number you referenced is for up to 30 feet so it would not be ideal for you.

    This is a two fold answer according to my technical contact at Ultra-Fab. If you happen to be turning at the same time you are backing up then you will want to go with the caster type wheels # UF48-979011 that you referenced. I do want to mention that swivel casters are for motor homes up to 30 ft long. In you only hit ground when you are backing straight into your driveway then you will want the roller type, Ultra Fab # UF48-979023. Both wheels have advantages. The caster is good...
