Video Transcript for Ultra-Fab Products Skid Wheels - Hitch Mount - UF48-979018 Review

Today we're going to be taking a look at part number UF48-979018. This is the Ultra-Fab Hitch Mounted Steel Rollers for RVs with 3 inch hitch tubing. The unique rollers are going to clamp around the cross bar of your RV's rear hitch, and that's going to help prevent tail dragging and digging in while the RV is backing up. All the mounted hardware is included. Everything you need is included. It's going to feature a heavy duty steel construction.

It looks like it's got a nice protective finish on it, so it's not going to rust or corrode on you but, again, very strong, very durable. One of the neat things I want to point out is here on the inside of the rollers, we're going to have some bearings. Just like with anything else, bearings need to be lubricated for proper operation. What Ultra-Fab does is they put a grease fitting here in the bolt head. That way you can attach a grease gun to it, and simply just pump in your grease, and it's going to lubricate the bearings so really nice design, easy maintenance with these. It's designed for 3 inch by 3 inch square hitch tubing.

The roller diameter is going to give us a measurement of about 3 inches. If we take a measurement of the roller width, that's going to give us a measurement of 2-1/4 of an inch. With this part number, you're going to get 2 full assemblies. The u-bolts simply go around the tubing on your hitch then on the bottom of the hitch, so these would go around your tubing. Then in between the tubing and the roller assembly would be this bracket right here, this mounting plate. The mounting plate is going to sit directly on top of this bracket and on top of the roller assembly.

Then these are going to come around the tubing, drop through there, and then on the bottom side, you would install the lock nuts that are provided. If we take a measurement of the plate, measuring this direction, that's going to give us a measurement of 4-3/4 of an inch. Measuring this direction, that's going to give us a measurement of about 5-1/2 inches. The thickness of the steel plate is going to be a 1/4 inch. If I put that plate back on top of the roller assembly because that's how it's going to be installed, if we take an overall height measuring from the bottom of the roller to the top of this plate, that's going to give us a measurement of about 3-3/8 to 3-1/2 inches, so right in that range. That's about how far it's going to be hanging from the bottom of the tube of our hitch.

Again, it's designed for 3 inch by 3 inch tubing. That's going to do it for our review of part number UF48-979018. .

Easy bolt on application for my 35' 95 Holiday Rambler. Also had rear springs rebuilt and raised nominally to correct this notorious tail dragger model. Still drags occaisonnaly but these allow me to ride through. Built tough and well. Thank you for a quality American made product. 321185

Received the product yesterday it came much sooner than expected. It is much stronger looking than the pictures . Will not be able to install it till the weather gets better but it really looks great. 109181

Replaced my worn out tail dragger wheels with these steel rollers. Easy install, look great, angry the grease fitting are an added bonus. Shipping was fast! 324693

Heavy duty and well made. These bolted up nicely to my 3" receiver tow bar. I was surprised as to how well these appear to be made. These will last a lifetime. 760330

- UF48-979018

The rollers arrived in perfect shape and promptly. I was very pleased that the U-bolts were sufficiently long to allow me to incorporate a 1/2 inch thick shim or more to get the rollers lower on structure that is 3 inches by 21/2 inches. They take the load imposed when entering/exiting my steep driveway from the street which was were wearing away the fixed skids that were dragging on the pavement. 697996

- UF48-979018

Works great easy to put on if you’re RV is dragging these well help for sure I would buy them again if I needed them 692969

- UF48-979018

Rollers install in less than 10 minutes. They work great and do not mark my driveway like my previous set. Low profile so they don't hang down. Built really sturdy and should last the life of my trailer. Grease fitting is conveniently located on the end of the roller axle. 681053

- UF48-979018

Spacer could have been a little thicker, or if there were someway to adjust the distance so the wheels could be closer to the ground, but other than that, it worked as designed. 659689

- UF48-979018

Seem like very good quality. Still have the factory guards on the hitch but wheels will hopefully take over when they fail. The right side of factory guards mostly worn through already I assume from the trip out from the manufacturer in Indiana to so cal. 642760

Arrived and one was installed today. I adapted it to a use that is different than the product was intended for. I put it on my utility trailer just behind the ball coupler. It should help with it dragging entering and leaving parking lots. 447884

Very Good!Thank you! 418012

I recently purchased some skid wheels from etrailer which happened to be the wrong size. I contacted customer service and was very pleased with the help I was provided. My return was taken and the very friendly and knowledgeable staff member pointed me in the right direction and I ordered the proper skid wheels for my RV. Thanks MG 386876

Works as advertised. A rubber or plastic facing of the rollers would help with the scraping of the driveway and street (weight of the RV is sufficient to mark the asphalt street and the gravel texture of the driveway). 340737

Etrailer is one of the best comapanies you will find online. This product, like all the others I have bought from them, was shipped incredibly fast, fit perfectly on my vehicle, and had a very reasonable price. It doesn't get any better than this. 318126
