Video Transcript for Ultra-Fab Products Skid Wheels - Hitch Mount - UF48-979015 Review

Today we're going to be taking a look at part number UF48-979015, these are the Ultra Fab hitch mounted skid wheels for RVs up to 30' long. The unique casters are going to clamp onto the rear trailer hitch receiver of your RV to help prevent tail dragging and digging in while backing the RV up. You're going to get the mounting brackets and the hardware so everything that you need for a complete installation is going to be included with this part number. Everything is going to contain sturdy steel construction, located inside of the wheel are going to be extra durable roller bearings, these are going to be very long lasting. Also each wheel is going to contain a grease fitting that way you can hook up a grease gun, you pump grease in there to keep those bearings lubricated, so the grease fitting's going to allow for easy maintenance and lubrication. Each steel wheel's going to contain 1/4" thick urethane layers here on the outer edge of each wheel. It's going to provide an anti-skid barrier and it's going to ensure that the wheels last a lot longer.

Again, this is designed for low profile motor homes that are up to 30' long that have square hitch tubes. The mounting plate holes are going to fit either a 2 1/2" by 2 1/2" or 3 1/2" by 3 1/2" hitch tube. Each bolt right here is going to measure 5" long from the bottom of the bolt head to the end of the threaded portion. To get this installed, one plate is going to go on top of the wheel assembly and then you're going to have the hitch tube and then another plate's going to go on top of the hitch tube, and then you're simply going to connect the two plates with the 5" long bolts, lock washers, and lock nuts. The diameter of each wheel is going to measure 4", if we take a measurement of the wheel width, outer edge to outer edge, is going to measure about 2".

These plates, they're going to measure 5 1/4" by 5". If we put a plate on top here, the holes are going to line up perfectly. Again, this plate's going to make contact with the bottom edge, or the bottom surface of the hitch tube so the wheel is going to hang down from the hitch tube. Measuring from the bottom of the wheel to the top of this plate, that's going to give us a measurement of about 4 3/4" when the plate is on top of the wheel assembly. With this part number you're going to get two assemblies, so everything that you see here on the table is going to be included with this part number. That's going to do it for our review of part number UF48-979015.

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. 511900

by:

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. 479989


Comments

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.

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. 515993

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! 659244

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! 560535

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. 657602



- UF48-979015
by:

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. 604662

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. 325995

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. 229358

Easy to install, looks great, work great so far on first trip out. Only challenge was length of screws - too long. Otherwsie, very happy with purchase. 218119

Not that thrilled with this kit. Pros: Heavy construction seems well suited to the task Cons: 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 130262

Ask the Experts about this Ultra-Fab Products Skid Wheels
Do you have a question about this Skid Wheel?


  • 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.

  • Skid Wheels for 2011 Forest River Berkshire 390QS Class A Motorhome
  • We carry many types and sizes of RV skid wheels, all of which are shown on the page I linked for you. The two basic types are frame-mount and hitch-mount and we have both weld-on and bolt-on installation products. For a 40-foot Class A like your 2011 Forest River Berkshire 390QS you can use # UF48-979013. These are a weld-on install.

  • 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.

  • 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.

  • 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 Wanted for Underside of Utility Trailer
  • I'd recommend the Ultra-Fab # UF48-979015. These wheels can be through bolted into the underside of the trailer, and the included backing plates can be used to prevent the bolts from tearing through the trailer deck.

  • Parts Needed For Yard Ramp Build
  • Making a custom ramp like this takes some unusual parts, but I think I can help. For the wheels, I recommend the Ultra-Fab Hitch Mounted Skid Wheels for RVs up to 30' Long - 4" Diameter - Qty 2 # UF48-979015. For the 2 speed manual crank jack, I recommend the Square 2-Speed Jack - Drop Leg w/ Spring Return - Sidewind - 12-3/8" Travel - 10K # TJD2SP-12000SP-F. I don't know what you mean by tow boot. I assume you want a combo bar like # E-9 or a receiver like # UF35-946401. For...

  • Dimensions of the Skid Wheel UF48-979015 Plate
  • I went out into our warehouse to measure the dimensions of the plates that you asked for. I attached a picture that has all of the dimensions, but the overall size of the plate is 5 inches by 5.3 inches, the distance from one column of holes to the other is 4.168 inches. The closer holes are 1 inch apart, the further holes are 3 inches apart, and the hole diameter is .418 of an inch.

  • 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.

  • 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.

  • Can the Ultra-Fab Hitch Mounted Skid Wheels # UF48-979015 Attach to 4 by 4 inch Hitch Tube
  • The Ultra-Fab Hitch Mounted Skid Wheels # UF48-979015 that you referenced would work well when attached to a 2-1/2" or 3-1/2" square hitch bar. There would be no interference at all. I attached a review video for you to check out as well.

  • 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.

  • 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. We do not have a skid wheel that will accommodate the size of your bumper without having to drill through your frame. The # UF48-979015 skid wheel...

  • Skid Wheel Recommendation to Fit 3.5 inch Square Trailer Hitch Tube
  • We have just what you need. The Ultra-Fab Hitch Mounted Skid Wheels # UF48-979015 can fit on hitch tubes that are up to 3.5 inch by 3.5 inch just like what you have so it'll fit well. I attached a picture that shows what it looks like installed as well.

  • Do Ultra-Fab Skid Wheels # UF48-979015 Have a Weight Capaicty
  • 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. A review video and the installation instructions have been linked for you to reference as well.

  • Skid Wheel Recommendation for 5th Wheel Camper 33 Feet Long
  • 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. These skid wheels are designed for RV's up to 34 feet long. These skid wheels come with brackets that weld to the trailer, and then the skid wheels are bolted to the brackets. The...

  • What is Actual Bolt Length for Hardware in Ultra-Fab Hitch Mounted Skid Wheel Kit # UF48-979015
  • I pulled one of the Ultra-Fab Hitch Mounted Skid Wheel kits # UF48-979015 from our warehouse and measured the included mounting bolts. 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. I will have the written specs on the product page updated to reflect the actual bolt length. The wheel bearings are not sealed/waterproof, but they do include a grease zerk fitting to let you easily...

  • 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.
