Today we're going to take a look at the Ultrafab five inch diameter ultra swivel skid wheel for the class C RVs up to 34 feet in length, and it's for a quantity of two. Now, these unique casters attach to the frame of your RV, and they help prevent tail dragging and digging in while backing up. They are a drop forged caster for superior strength to other casters, and if you notice they use extra strong metal wheels, and extra durable roller bearings, which are long lasting. If you notice they do have a Zerk fitting on the wheel here, and the Zerk fitting right here on the caster. This allows you to grease the bearings on the casters, and the bearings on the wheels. If you notice on the wheels, it also I a quarter inch think urethane layer on the outer edge of each wheel.

This provides and anti-skid barrier, and it insures that the wheel will last even longer by avoiding wear to the metal wheel.These brackets is what you'll weld to your RV, then you'll bolt the skid wheels to the brackets using the included hardware. Application again, is for class C motor homes up to 34 feet in length. The wheel diameter is going to be five inches. So, you can see if we put a ruler on that there's your five inch diameter. Does include everything laid out here on the table.

The two casters, the two steel mounting plates, the installation hardware, which is 12 bolts and nuts, and a nice set of detailed instructions.Now, one note on these. They are not recommended for use on diesel pusher motor homes due to the extreme rear end weight of that motor home.

Attach these sturdy steel wheels to the rear of your RV to help prevent tail dragging when backing up. Protect your undercarriage from unnecessary damage.

by:

The wheels look ok, when the plates didn’t fit my frame I called, answer was of no help. Basically told they bought this product line and we’re not going to support it.



by:

Replaced OEM skid plates with this skid wheel. Haven't driven yet, butso far it was an easy install and IMO much better then the OEM installed skid plate.



by:

I purchased these about a year ago to try and get my 34 foot fifth wheel up a fairly steep incline to a pad in my backyard. I was a little apprehensive about purchasing these as I wasn't sure they would work - and I should have trusted my instincts as they didn't. I tried them out once and in the process of backing up the hill one of the weld joints did not hold and the wheel collapsed. I could then see that it wasn't going to be possible to get the RV up onto the pad so I called etrailer to see if I could at least return the wheels(which weren't damaged) and the bolts that came with them. I knew that I wouldn't be able to return the steel plates that were welded to my frame. etrailer told me that I couldn't return any of these since I had used them. So, I am now stuck with skid wheels that I have no use for. So, beware if you purchase these and try them out - you'll be stuck with them!

HI Timothy, Thanks for your feedback! These wheels are not meant to be load bearing. They are specifically for keeping the back of the trailer from bottoming out, saving the bumper.



by:

I bought a set of the 'dolly' wheels for use under my Class C motorhome. Utilizing the on-line instructions, the job appears to be straight forward. Hoping 'dolly' wheels will end the scraping of the rear of the camper on the pavement in front of my inclined driveway. Will be waiting for warmer weather to have mounting pads welded to the frame of the motor home.

I have been very satisfied with the skid wheels. Better to roll across the surface than to grind against the ground or concrete.



by:

This was one of the best purchases we have made for our RV. No butt bumper dragging in dips. At one campground one guy didn't wait for us to park our RV. He asked where we got our wheels, so we told him. While there we saw many people bottom out in that dip and were confident that it didn't need to be if they had put on skid wheels.

This set of wheels was the best investment we have made so far. After a years use we dont worry about dips or uneveness in the roads or driveways. These wheels take care of all the problems that have come up so far. I HIGHLY recommend these wheels.



by:

I put these on a 33' Crusader fifth wheel to keep from ripping up the driveway every time I pull in/out.

After a year still working great!!



by:

Purchased these for our 33 ft travel trailer that bottomed out every time we pulled it down the driveway. We welded them to the frame towards the back and it did the trick.



by:

We have a sloped driveway and have to use boards to back up the RV, which takes time and a lot of effort. The new skid wheels that we had welded to the rv works great, no more boards. We have had a number of people (with rv’s) ask us at gas stations about them. We are very pleased with this our purchase, wished we had known about these years ago.



by:

I bought this item for my motorhome installed them they worked really good for the low slope on my driveway.

This product has done all it was designed to do it makes it much better to get my motorhome in and out of my driveway



by:

We are very happy with these skid wheels! The welder that installed them for us said that they were very heavy duty and will work well. We just got back from a week camping trip, and the wheels saved us going out of a steep driveway. They work great! Highly recommend these! We have a 29’ Class C.



by:

Unhappy with hold down, you suggest to use 21/2” u bolts but don’t supply? Only after I received product . Will not do any more business with you….

The 2.5 inch long bolts are only needed if the skid wheels are installed with the alternate bolt on method. The hardware is included for the weld on method that this is meant to be. Ultra Fab makes a bolt on application that includes 2.5 inch long bolts in part # UF48-979017.



by:

I ordered a new set of skid wheels from etrailer and was very very pleased with the service the product and the price. Ellen M was very helpful in making sure I ordered the right wheels for my rv. My order was shipped and arrived in a couple of days.
I would highly recommend this company to any one



by:

Giving bolt hole pattern dimensions would be helpful. Had to modify my mounting plates to attach the new wheels.
Look to be excellent quality.



by:

Excellent product! Easy installation and works very well!



by:

Great product worked as advertised. I put it on a 32 foot rv. No more digging into my asphalt drive

After a year of use this product is still great. I was worried it would not hold up but it has. I would recommend



by:

This is a good product. With some minor adjustments I was able to make it work well. I was disappointed that the plates were rusty. It appears that the package had been opened, left out and then returned. Otherwise, good.



by:

Good Web site. Mailed promptly. Good v alue.

  • Replacement Zerk Fitting For The UltraFab Weld-On Jumbo Steel Roller # UF48-979012
    Hello Gaby. I reached out to the manufacturer and found out that the UltraFab Weld-On Jumbo Steel Roller # UF48-979023 uses a 6-1.0mm Zerk fitting. For a replacement you can use the following: - Replacement Brass Grease Zerk for Weld-On Hinges - 6 mm x 1.00 STD # MA35ZR

  • Recommended Solution For A 2014 Primetime LaCrosse 318 BHS That Scrapes The Ground
    You could mount some skid wheels to the frame by your stabilizers to have them hit first and protect the stabilizers and the rest of the undercarriage from scraping when coming out of a steep incline/decline. I recommend ones like the Ultra-Fab Skid Wheels # UF48-979012. These wheels have brackets that will weld onto the frame and allow you to bolt on the wheels so that if the wheel ever wears down you can easily replace it.

  • 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.

    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.

  • Determining Size of Skid Wheel for Winnebago Aspect 27K
    We have our skid wheels listed by size relative to the length of the RV but at the end of the day I would go with whatever size you think would work best. In general the longer RVs like over 36 feet call for 6 inch diameter skid wheels like what comes with he Ultra Fab 6 inch wheels part # UF48-979013 which are weld on. And then for shorter than 34 feet we have the 5 inch diameter setup part # UF48-979012. Since your 2013 Winnebago Aspect 27K is 30 foot I would think the 5 inch setup would...

    To install the Ultra-Fab Skid Wheels for Class C RVs up to 34' Long # UF48-979012 that you referenced you have to weld on the mounting bracket and then bolt the wheel base to the bracket. You cannot bolt the kit directly to your trailer.

  • Skid Wheels for a 31 Foot Forest River RV
    The best skid wheels for your 31 foot Forest River Forester are going to be the Ultra-Fab Skid Wheels # UF48-979012. The 5" diameter wheels are bolted to brackets which are welded onto your RV's frame. Please keep in mind skid wheels are only to help tail dragging when backing up and should not be relied upon to stop the full force of an RV from coming into contact with a steep driveway. They can help if the angle is such that the RV's rear truly does "skid" off the driveway, however.

    Hey Phillip, a weight capacity for the Ultra-Fab Skid Wheels for Class C RV # UF48-979012 that you referenced is not available. Since these are designed for use with motorhomes the are rated by length of motorhome. This one is good on RVs that are up to 34 feet in length.

  • Mounting Orientation of the Ultra-Fab Skid Wheels for Class C RVs up to 34'
    You can install the Ultra-Fab Skid Wheels for Class C RVs, # UF48-979012 the way you describe but yes that would change the stress as you identified. If too much or not, depends on the abuse you apply. These are intended to accept the abuse that would otherwise be on your trailer and then replaced if need be. I suggest you consider welding in the orientation you describe but also welding a block along side to minimize the span.

  • Recommended Skid Wheels For RV With Long Overhang Towing A Trailer
    We have skid wheels exactly for this issue. The skid wheels attach to your vehicle hitch frame and allow you to deflect the hit to your vehicle frame, bumper, or panels. This will help prevent dragging and protect your undercarriage from unnecessary damage. I recommend the Ultra-Fab Rotating, Hitch Mounted Skid Wheels for RVs up to 30' Long - 4" Diameter - Qty 2 # UF48-979014. If your RV is longer than that, then hitch mounted is no longer and option, but we have the Ultra-Fab Skid...

    The Ultra-Fab Skid Wheels for Class C RVs part # UF48-979012 should work on pretty much any surface as they are really just a barrier to prevent the frame from making contact with the ground. The may not rotate in mud/sand as they would on pavement but they should still do their job of protecting the trailer.

  • Recommended Skid Wheels for 32 Foot Class C Motorhome
    For your 4 inch bumper on your Class C motorhome, I recommend using the Ultra-Fab Skid Wheels for Class C RVs up to 34' Long - 5" Diameter - Qty 2 # UF48-979012. As long as your 4 inch bumper is welded to your frame, you can bolt these wheels to the bumper and be good to go as long as you don't have anything that hangs below your bumper.

  • Recommended Skid Wheels for a 43' Canoe Trailer
    Bryan, if it were me I'd go with caster wheels over fixed wheels. Mainly because a fixed bearing wheel can only be moved in a vertical direction and are not able to turn in a direction parallel to the wheel path. The only leg up I can think of is that fixed wheels are going to be a bit easier to steer since they only go forwards or backwards, other than that I think caster wheels take it. So something like the Ultra-Fab Skid Wheels for Class C RVs up to 34' Long # UF48-979012 would work...

  • Does Ultra-Fab Skid Wheels # UF48-979012 Have Weight Capacity
    Ultra-Fab Skid Wheels # UF48-979012 are designed for Class C RVs up to 34 feet long but do not have a weight capacity. Basically as long as the RV is less than 34 feet these will be rated properly. Since the wheels don't bear the full weight of the RV at any given point it would be hard to rate them and know how much weight an RV would be putting on it. The same goes for # UF48-979013 which are designed for Class A RVs longer than 34 feet.
