UF Ultra-Fab Products 48-979011 4" Ultra Swivel Skid Wheel

Just the ticket for the back end of my 27' Class C RV. We have a steep driveway to street angle and it would scrape terrible without these. Worked like a charm. The swivel probably won't last as long as a regular wheel would, but it works so much better during turns while backing up.

Acceptable quality and should do the job. One of the two coaster wheels arrived with grease fitting broken off. Given the design, the fitting was not critical as there are other ways to easily grease the ball bearings on the swivel.

Granted I did buy this 3 years ago, but for over $100 I figured it would hold up more than it did. The center of the wheel shattered and became useless real quick.

We fabricated these for the under rear of our 32 foot trailer to prevent it from scrapping the ground, as our dump hose is at the very end under our bumper. We welded these on there, and during our most recent trip these worked great for driveways and such

The price is high but afterbreaking several lower priced ones i stept over the price

We have a steep driveway on our new house and I had been dragging/scraping the bumper for about 2-3' when ever coming or going.I just installed these on our camper this weekend as we were pulling out for the last time this year before packing it away for the winter.At the bottom of our drive, as I turn onto the gravel road, I slowed to a crawl to make sure to touch these down as softly as possible.At first I was optimistic, as I parked on the side of the road to go survey the situation. I had not heard any scraping as before, nor did I feel the familiar "dragging". But as I approached the rear I saw that the passenger side wheel interior metal had just crumbled away, and it was just hanging off center. Had I spent $20 on these, I would say you get what you pay for, but I sure expected more from these based on the cost.Also, unless you plan to drill and tap the underside of your bumpers, or weld the plates on, you will need to buy the 3" square U-bolts separately, as they do not come with that hardware.

All pieces were there and it seems to be pretty heavy made. Has a zyrk fitting on it for the bearings. Haven't used it yet to see how it will hold up. Welded the plates to the frame of the trailer and then bolted the wheels to the plate. That way, the wheels can be replaced in the future if needed

They were very well made and appeared to be very sturdy. We returned them and got a lower profile for the ;back of our toyhauler to prevent drag.

We welded them on to the RV. The wheels hit the driveway each time in and out. Working as designed. Drive slowly.

Add to modify to bring them lower in the back to protect black tank. perfect installation
