Video Transcript for Ultra-Fab Products Skid Wheels - Frame Mount - UF48-979021 Review

Today we're going to be taking a look at part number UF48-979021. This is the Ultra-Fab Steel Micro-Roller for Trailers and RVs. The unique roller is designed to weld onto the frame of your trailer or motor home. That's going to prevent tail dragging and digging in while back your rig up. It's made from a heavy duty steel construction. It's very strong, very durable, raw steel finish here on the welding bracket.

It is designed to be a weld on installation. Here on this side, you're going to have a grease fitting that way you can pump grease in here and it's going to lubricate that inner portion of that wheel. I'll show you that real quick. We're going to have a slot right here, so you pump grease into the fitting. It's going to run through here. It's going to come out and it's going to lubricate all inside here that way it makes for a really nice, smooth operation.

Then you've got the lock nut on the other side that you'll have to tighten down. When it comes to the overall dimensions, if we take a measurement from outer edge of the bracket to the outer edge of the bracket that's going to give us a measurement of about three inches. The diameter of the wheel is going to measure two inches. If we measure the width going straight across, outer edge to outer edge we're looking at about two inches. Then taking a look at the overall height, that's going to give us a measurement of about two and one quarter of an inch.

That's going to do it for today's review of part number UF48-979021. This is the Ultra-Fab Steel Micro-Roller for Trailers and RVs. .

Help prevent damage to your RV's undercarriage by welding this 2" diameter steel wheel onto your trailer or RV frame.


I think these were definitely worth the cost. I have a rather steep driveway and knew I was running the risk of dragging the tail end of my brand new tilt deck trailer. So, before taking delivery I sketched up my idea for removable drag rollers and turned the dealer's fabricators loose to make it happen. They turned out better than I hoped and work like a champ. It might be a bit of a chore to get them on and off (no more than 5 mins/side), but was necessary to maintain the loading edge getting all the way to the ground.


Overall I have to give this skid roller a low rating. However if I rate the parts individually I have better results. The bracket is excellent, 1/4" thick steel and the holes are just the right size not too big. The roller is also excellent. The internal bearing is slightly wider than the roller so you can tighten the bolt as much as you want and the roller will still turn. The bolt is very poor. The hole for the recessed grease zerk is too deep weakening the bolt head. The head broke off before the head and nut even shouldered up the the bracket. Also the bolt is either grade 2 or 5. My advice: If you purchase this roller, replace the bolt with 1/2" grade 8; however you will no longer be able to grease the roller.



Manufacturer is aware of the problems with the bolt and is correcting the problem. They offered to replace the bolt, but I have already made a new one.


Just what I needed for my low rear frame clearance. No more getting hung going in or out of my driveway. Priced right, shipped quick and free(over $50).
etrailer always helps me get the job done.
Not a single trailer shop in Houston had them in stock. Half of them didn’t know what I was talking about.



Works great. Keeps my bumper from dragging going in and out of my driveway.


Not what I was looking for, but a good alternative. I wanted a roller width of 8 inches or more, but this little product worked well to avoid any damage to my trailer and minimize damage to the asphalt driveway. A groove the width of each roller and less than 1/16 inch deep sure beats the gouge the frame rails left. I’m pushing a 3,800 pound trailer into its storage canopy, so I expected the little wheels would compact the asphalt.
Local welding shop installed the two wheels for $42. The roller assembly was removed prior to welding the bracket, paint applied when cool, and roller assembly installed. Grease the roller and you’re ready to drag on your driveway.
Though smaller than desired, for what it is, it’s an excellent product.


They hold up great well worth the money they are on the back of a 24k 36 ft flatbed trailer with a dovetail that drags on almost all driveways I put 4 across the back and they get used a lot and hold up to the weight


This is a good quality product.


This is exactly what I needed to keep my bass boat trailer from scraping when I go out my driveway!


Seem to be well built.


Very well-made product. It's compact, low-profile, has minimal impact on ground clearance, and will prevent the end of my 24' enclosed car trailer from dragging when traversing over sudden or excessive gradient changes which could cause damage. The weld-on installation adds an extra measure of security knowing that it won't vibrate loose and potentially fall off or shift and not provide the protection is was designed for. I highly recommend this product.

Woody P.


First trip paid for the product. Turning in to the hotel parking lot was a steep grade and voila, the wheels did their job perfectly. Buy them if you dont have them already.


I was looking for some of these for my 24 foot trailer on the internet when I came across your site. I look at them on E-bay and amazon. You had the best price and free shipping that sold me. Now to get them welded on....

John H.


Work great ... very well made..Installed on 24 foot enclosed car hauler by pace


Have been using this roller for one year. Very satisfied. Our drive is lower than the blacktop street in front of our drive so as the front of the truck and fifth wheel trailer went up and of course the rear of the trailer went down and would let the bottom of the rear hitch drag on the drive and leave rust marks. It doesn't put a lot of weight on the hitch and this roller welded to the bottom of the ball hitch works perfectly to keep the ball nut from dragging.


Just had these welded to get up my steep driveway without scraping. They make a loud noise but no scraping or digging in to my asphalt driveway.


my trailer would drag with a load. these wheels are outstanding durable wheels and work great. no more drag marks in my driveway

Paul F.


Still working great.


Drag and go!


no happy with this product center bolt snapped at zirk end upon installation with almost no torque on it is there an new bolt available. I have these on the back of my cargo trailer

We've been in contact with Ultra-Fab about the broken bolt and were coordinating with them on getting the hardware to you. We'll be in touch.


One year later this is still a great product! Every time I park our 5-Wheel in our driveway they come into play by preventing the bicycle hitch from dragging. Prior to having them installed I was concerned about dragging anytime I left the primary driving surface. No more! Total cost for the drag wheels plus installation was about $$...a bargain for just peace of mind.


We are very happy with these skid wheels. We welded them to the bottom of the drag bars on our camper and they have performed as expected.



A year later and several trips, we are still happy with these skid wheels.


Not having this product my trailer got dragged on a parking lot apron. The structure below my back ramp door rolled out locking the hinge up on the ramp door. The steel on the door also had to be replaced after we forced open the door. Huge job that I don't have to worry about doing again thanks to this product. Welded up painted and installed the wheels with grease in under a hour. Re skinning the back door, c channel replacement on the door, angle iron across the bottom of the trailer, new hinge and lights with new wiring 32 hours and $600.00 in steel.


Great product as advertised. Arrived as promised. Welded them on and added a coat of paint. Ready to go. As simple as that.


received exactly as described. Looks to be a great product !!
Very HEAVY duty. Can't wait to get them welded on and to get them scratched up instead of my trailer.

Ed L.


This product has saved the rear of my trailer, on more than 2 occasions. Great investment if you actually tow your trailer


I waited to post my review until I had some good use out of these wheels. I have a steep driveway and was dragging so much I needed 4low to get the boat parked in the driveway. Instead of spending thousands on a new drive I decided to try these out. They have worked great! Instead of dragging the trailer it now rolls in and out easily. I’ve also had a couple hard hits pulling out of gas stations and the wheels remained sturdy and still roll smoothly. Highly recommend.


Great fit and price. Our boat trailer drags when pulling out of the driveway. Leaving gouges in the surface. With the weld on micro rollers, the trailer rides on them nice enough to keep the driveway surface and trailer from further damage.


Just received Ultra Fab Mini Steel Roller. Have not had a chance to weld it on, but it looks like it is built to do the job of preventing my 5th wheel frame frame dragging as I pull out of my steep driveway. I like that it has a zerk fitting to lube the roller.


A great product and, as always, great service from etrailer


Have not installed it yet, but it looks well made. Has a hollow / side drilled bolt with a zerk fitting on the end for easy lube maintenance. Unfortunately the roller has rust on it right out of the package. I'm sure that will get worse quickly after it is installed under my vehicle. Once it's welded on and lubed I will have to shoot it with some black paint to try to prevent the continued rusting. Other than the rust it appears to be a good product at a reasonable price.

  • Recommended Suspension Enhancement For a 2007 Toyota Sienna That Sags When Hauling a Trailer
    With the Coil SumoSprings Custom Helper Springs # CSS-1195R this will help to prevent your suspension from sagging as much when you have the trailer attached on your 2007 Toyota Sienna. While we do not have any suspension enhancement that is designed to raise your ride height of the rear of your Sienna, these may slightly raise the height depending on how much your stock springs have sagged over the 14-15 years old your van is. To install these you only need to raise your rear suspension...

  • Comparing Ultra-Fab Steel Micro-Roller and Jumbo Roller For Trailers and RV's
    The main thing I would look at is the surface area between the Ultra-Fab Steel Jumbo Roller # UF48-979023 and Ultra-Fab Steel Micro-Roller # UF48-979021. The Jumbo Roller is going to have a slightly larger surface area with the size of the roller being larger 2-1/2" diameter vs 2" on the Micro-Roller. This will lead to less sinking in on softer asphalt surfaces that you may encounter and the wheel will more easily roll over small rocks and debris on the road surface.

    I have a couple items you might consider before trying to add larger tires and wheels. The first is a Correct Track Trailer Alignment and Lift Kit # LC87120. This will allow you to lift your trailer 1-1/4" or 2-1/4" to gain the clearance needed not to drag on your driveway. Next you can weld on the Ultra-Fab Steel Micro-Roller for Trailers # UF48-979021. This will protect the trailer from digging into your driveway and causing any damage. The wheels will allow for the trailer to roll...

  • Skid Wheel Needed for Coupler with Safety Chains Loops in the Way of Hitch Pin Mounted Wheel
    Since the location of your hitch pin hole and the safety chain tabs don't allow you to use a skid wheel like part # UF48-979020 or # RM-050, the only other option that may work is if you welded a skid wheel like part # UF48-979021 onto the bottom of your hitch receiver. The only issue with this is that if you have a fairly hefty vehicle it may not hold up very well as there is a note not to install it on a diesel pusher motorhome.

  • 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.

  • Available Weld-On and Bolt-On RV Skid Wheels to Reduce Ground Contact
    Skids wheels come in several varieties and sizes but what they all have in common is that they are intended to 'take the hit' from ground contact instead of your RV's frame or hitch doing so. How long any set of skid wheels will last depends on how often and how hard they impact the road. As this is pretty tough to quantify these items do not have weight ratings per se. Most are recommended based on the RV length. A larger size skid wheel like bolt-on kit # UF48-979014 is apt to make contact...

  • How to Pick Between the Micro and Jumbo Ultra Fab Trailer Rollers
    My day is going great, thanks for asking. The biggest factor to consider when choosing between the micro roller part # UF48-979021 and the jumbo # UF48-979023 that you referenced is the overall height of the two. The micro measures 2-1/4 inches tall and the jumbo is 3-1/2 inches tall. Depending on where you would install the roller and how much height you would need to prevent other portions of the trailer from dragging is how you would pick between the two. Neither really have a weight...

  • Recommended Skid Wheels for a 2017 Winnebago Fuse 24 RV
    There are 2 styles of skid wheels that people install on their RVs - frame mount (which weld on) and bumper mount (which bolt around the bumper). For your 2017 Winnebago Fuse 24 I recommend going with a frame mount option. The Ultra-Fab Steel Micro-Roller for Trailers and RVs # UF48-979021 is what I recommend going with.

  • Trailer Rollers For Tail Light Lenses That Are Constantly Damaged On The Ground
    You may benefit from adding some Ultra-Fab Steel Micro-Roller for Trailers # UF48-979021 as I typically see your Wesbar Tail Light 403075 being damaged from dragging on the ground. This tends to happen with trailers that sit low maneuvering onto a hill or curb. These can be welded on the back of the trailer near the tail lights to help prevent the tail lights from scraping on the ground. We do not have any guards that are the correct size for your light.

  • Can Skid Wheels be Used to Help Keep 5th Wheel Trailer from Bottoming Out with Steep Driveway
    You definitely can install the Ultra-Fab Skid Wheels # UF48-979013 on your 42' 5th wheel but it is worth noting that the wheel and caster plate measures 7-1/2" tall so if the 16-1/4" that you measured is from the frame rail then that means your ground clearance will be reduced to 8-3/4" which really isn't much at all. If your frame sits below the skirting on your 5th wheel trailer then you should be able to use a shorter option like the Ultra-Fab Steel Micro-Roller # UF48-979021 which...

  • Can Ultra Fab Skid Wheel be Used on 40 Foot RV
    The Ultra-Fab steel roller # UF48-979021 doesn't have a weight capacity. It is almost solid steel, the bolt runs through the middle, so it can handle a significant amount of stress. But considering that your Winnebago is 43 feet long you might consider going with the larger model, # UF48-979023. It is 2-1/2 inches wide by 3 inches tall. Either way the more of them you use the less stress and weight each individual one has to handle.
