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.


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.


I have used these skid wheels before they work excellent, they are very easy to weld and to mount, I highly recommend these if your trailer drags anywhere


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.

Great quality heavy duty caster. E trailer has excellent customer service. If you ever have an issue they will go the extra mile to make it right.


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.

These are quality rollers and the grease fittings keep them rolling freely with a little maintenance.


Buckle holds good and good protection if it comes in contact with the product is it tying down.


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


these rollers look like they will work great on the back of my car trailer.


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.


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.


Easy to take apart and weld to the trailer. This unit has held up well and has worked as anticipated. Grease fitting is nice too.


My new enclosed car trailer has considerable overhang on the back and I wanted to protect the back crossmember from dragging in the event of having to maneuver steep approaches. I made a triangular 1/4" plate and welded the skid roller fixture to the plate, then bolted to the framework with five points of contact to spread the load. The two skid rollers are a perfect solution for protecting the rear crossmember from damage.


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.

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....

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

They work well. Should paint the brackets and weld to prevent rust. Recommend removing wheel and bolt before welding brackets


Work Great


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.


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.

look sturdy and well made. will find out how they work after installation

no complaints from customer, was on a car trailer that would dig in. now rolls.
Jeff P - 12/11/2018


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.


Product works well. Appreciate the fol lowup.


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.
