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. .

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. 527926

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. 219783

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. 477945

Roller didn't work now frame is bent. Problem is that all dips do not come head on in fact a lot are when you are turning. Roller will not compensate for that. Very disappointed. 435666

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. 133844

I used this steel roller on my front gate which used to have a hard rubber roller that would wear out in 6 months . Fits perfectly and the gate opens quietly now. Since this roller is steel, I hope to never have to replace it. 547384

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. 121052

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.

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. 541377

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 398168

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. 465087

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. 131205


Comments

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.

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. 424529

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. 383006

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. 371865



- UF48-979021
by:

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. 353398

Do you have a question about this Skid Wheel?


  • Recommended Skid Wheels for a 34' Coachmen Apex Ultra Lite Trailer
  • For your 34' Coachmen travel trailer I recommend installing weld-on rollers like part # UF48-979021 or # UF48-979023 to help protect your trailer while going up your driveway. We do have some bolt-on options but they are meant for trailers or motorhomes that have hitches on them.

  • 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.

  • How to Lift a 2018 Forest river Grey Wolf 26DBH 3" for Ground Clearance
  • We do have over-under conversion kits from Dexter Axle that you can install on your trailer. Part # K71-384-00 is for a 2-3/8" axle while part # K71-385-00 is for a 3" axle. These kits allow you to move your axle from being above your leaf spring stack to under it. This means that the height gained will be equal to the diameter of your axle plus the height of your spring stack. Something else you may be interested in adding are some skid wheels like part # UF48-979021 (Qty 1). This...

  • 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...

  • Thank you for providing a photo diagram of your 5th wheel rear frame area where you are intending to install Ultra-Fab Steel Micro-Roller Skid Wheels # UF48-979021. The best location to weld on these rollers is at or just behind the point where the trailer's frame is making contact with the ground. If your indicated location is making contact with the ground (but nothing behind it is) then it would be a suitable spot. If there is scraping behind your indicated location, such as on the...

  • Skid Wheel Recommendation for 28 Foot Cargo Trailer
  • For a cargo trailer a smaller set of skid wheels like the part # UF48-979021 would be a great option. They are 2 inches in diameter and will weld to the trailer frame.

  • 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 a 3-1/2 Inch by 3-1/2 inch Hitch Cross Tube

  • 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.

  • 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. They will need to be weld onto your frame (by a professional welder) and prevent damage to the undercarriage of your RV. The roller itself is 2 inches in diameter and...

  • The Ultra-Fab Rollers part # UF48-979021 that you referenced should work well for you. The overall height of this roller is 2-1/4 inches so while the roller would contact the ground sooner than without the roller it will help prevent damage to the undercarriage of your trailer.

  • How Many Ultra-Fab Steel Micro-Rollers Should be used on a 40 Foot 5th Wheel Toy Hauler

If you have a place in the center of the trailer to weld on another then I would definitely go with 3 with the other 2 on each frame rail as far back as they can go. I have included a link to a video review of this roller for you.

  • Skid Wheel Recommendation for Hitch Installed on a 2012 Freightliner Sprinter
  • The best solution I could make for you would be to have the Ultra Fab Micro Roller Skid Wheel part # UF48-979021 welded to the bottom of your hitch opening. This would work great with the Draw Tite Hitch part # 75549 that you have on your 2012 Freightliner Sprinter with a 170 inch wheelbase.

  • 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.

  • Does the Ultra-Fab Steel Micro-Roller have a Weight Capacity
  • Ultra-Fab Steel Micro-Roller # UF48-979021 does not have a weight capacity. It is designed for use on all motorhomes, travel trailers, and 5th wheels so it is going to be strong. There just isn't any type of load rating for it.

  • Skid Wheels for 2015 Forest River Micro Lite 25BHKS Travel Trailer
  • Welding aluminum can be tricky and welding steel to aluminum can be trickier still due to the different melting points of the two metals. If your trailer's frame is indeed aluminum (I could not find this statement on the Forest River website) you'll want to check with them using your trailer VIN to find out if they approve of welding on skid wheels like the Ultra-Fab Steel Micro-Rollers # UF48-979021.

  • 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...

  • Skid Wheel Recommendation for a Trailer to Replace Stabilizer Jacks
  • I may have a solution for you, but the part # UF48-979020 that you referenced is designed to attach to the bottom of a 2 inch hitch opening so it wouldn't be a great solution for you. A weld on roller like part # UF48-979021 might be a better option.

  • Skid Wheel Recommendation for Smaller Utility Trailer
  • For such a lightweight trailer you would instead want to go with the skid wheel part # UF48-979021 to mount on the frame of your trailer. These skid wheels will stop your trailer from dragging and are only 2 inches tall so they wouldn't significantly reduce your ground clearance. These will need to be welded on.

  • Can the Ultra-Fab Steel Micro-Roller be Installed on Featherlite Aluminum Trailer
  • The Ultra-Fab Steel Micro Roller # UF48-979021 has a steel bracket that is designed to be welded to the frame of the trailer. If your Featherlite trailer has an aluminum frame, welding the # UF48-979021 will be tricky. Aluminum has a much lower melting point than steel, so welding these two types of metals together is not easy. The best solution for welding the steel roller to an aluminum trailer frame is to take it to a qualified welder who is comfortable working with these two metals.

  • Design of Center Bolt with Grease Fitting on Ultra-Fab Steel Micro-Roller for Trailers and RVs
  • I spoke with my contact at Ultra-Fab about the grease fitting in the bolt on the Steel Micro-Roller # UF48-979021. She said that the design was changed a little over a year ago, changing the fitting from a press-in fitting to a screw-in fitting. My contact confirmed that they do not typically have problems with the bolts or other components of the # UR48-979021.

  • Ultra-Fab Skid Wheel Recommendation
  • I just spoke with our Ultra-Fab contact about the Steel Micro-Roller, part # UF48-979021. They told me that the bolts that they were experiencing problems with in the past have been replaced and all of the skid wheels we now offer have the newly designed bolts. They said these are up to the task and should cause no problem at all.

  • Recommended Skid Wheels for a 29 Foot 2016 Forest River Sabre Light 5th Wheel Trailer
  • The Ultra-Fab Skid Wheels # UF48-979011 are a good option for your situation. Your trailer's length comes in just under the recommended max of 30 feet, and the 4 inch diameter wheels will easily handle the drag that you're experiencing. However, these skid wheels are going to stick out below your trailer's frame about 6 inches. To avoid any ground clearance issues, I would recommend part # UF48-979021. These smaller skid wheels will give you better ground clearance while eliminating...
