Video of Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers - 3,500 lbs
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to review part number UF35-946402. This is the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for Four Inch Square Bumpers with a 3,500 pound weight capacity. This trailer hitch receiver will clamp onto your RV's rear bumper. As you can see, these U-bolts, which are all included, they are four inch by four inch so they are designed to clamp onto your four inch square bumper. This will provide a receiver opening right here for hitch mounted accessories such as bike racks and cargo carriers or even light duty towing. It is made of a heavy duty steel construction, has a nice black powder coat finish, helps provide excellent corrosion resistance.
The hardware, the U-bolts, everything is included for the installation. Again, the application for this is on a four inch by four inch RV bumper. The receiver opening is two inches by two inches. Maximum gross trailer weight capacity on this is 3,500 pounds. The maximum tongue weight capacity is 350 pounds but the thing you do want to check is the bumper that this will be attached to, you want to check the weight rating of that bumper. You do not want to exceed that weight rating of the bumper so if the weight rating of the bumper is lower than this, than you would have to go by that as your guideline.
Also, it is designed to mount like this. You can also turn it over if you do want to mount this on top then you can mount it this way if you like also. If you'll notice right here, it has the included rings for the safety chains to hook to. Those are your safety chain loops hook up. One other thing, when you do use hitch mounted accessories on this, you do want to make sure that those hitch mounted accessories like a bike rack or a cargo carrier are RV approved accessories because you do want to make sure they're approved to be attached to a rear of an RV bumper. That should do it for the review on part number UF35-946402.

Arrived on time. Easy installation. Hauled approx. 250 lbs across rough roads with no problems. It's a good product and works well. 171298

I actually wanted the UF-946401 to hold a bicycle rack I already had, but it was on back order and I was leaving for a 1 month trip- So I got this instead. This thing is impressive, to say the least. Very heavy duty and really easy to install. No doubt it will work fine with a trailer. 194440

Installed this hitch on my fifth wheel to pull my side by side to the upper peninsula in Michigan, however I would recommend that you be sure your bumper is capable of the weight being towed. I personally removed my existing bumper and welded on a much heavier steel bumper. This hitch did exactly what was expected of it, thanks so much to Kirstin for her help at checkout 563754

Exactly what I wanted and expected. Arrived ahead of expected date and is in use as we speak. Will definitely recommend this product and company 90463

Hitch was exactly what i needed and very well built. it was also ten dollars cheaper thru etrailer than another well known rv parts supplier and i got free shipping by ordering a few more items i needed. shipping was prompt. can't ask for much more. 214161
by: dennis06/03/2015
Product was as described. Fit the bumper well, and hardware was well built. I am using it with a bike rack and its well made for that. 200081

I think the best thing to say about my purchase is I was helped by Janice and she was terrific and very patient with me. I was not rushed to make a decision and it was like speaking with a friend. I knew what I was talking about and what I needed, and so did Janice. It really was like having a beer with a friend. She said you must be careful with how much weight the bumper will hold, how much you can pull, and how much strength you will lose with using this extension. She was very helpful and said your plan certainly seems like it will work. We are buying more and more items on line and doing that with e-trailer makes it easy. We are just normal RV people, but when we buy something, like most people, we don't want an argument, we don't want issues, we just want our stuff as smoothly as possible and move on. e- trailer will do that for you. What they promise you will happen, it's not even a second thought when you buy something. 465264

Easy product to install and seems strong. That's the good part. The bad part is no one told me these things are bad to put on Camper bumpers. I bought this to put my bike rack into and it worked just as I imaged. Then I found out that the weight from the racks, and bikes puts stress on the bumper welds. I have not had an issue yet but I have seen and read about bumpers twisting from the weight and then the bumper rips right off! That's not a good thing. So I love it but I have only used it 2 times. 437364

Got hitch on time as promised. Instalation was simple and works great Thanks 53374
by: Vernon S.11/14/2013
Your product is good. I have to get a welder to move and remove some other items on my bumper in order to place it in the middle where it belongs. The U Bolts could have been 1/4 " wider. I had to hammer them onto the bumper and that spread the screw portion a bit. Other than that, I am pleased with the product and it arrived in a timely fashion. 107356

Shipping and response time was EXTREMELY fast, even with UPS Ground. I literally had the air ratchet out putting this unit on my camper trailer when I got this email to rate the product. Installation was absolutely a snap. Took longer to reposition the spare tire carrier than to put this rig on. Extremely sturdy and bulit out of heavy steel. Can't wait to sit the Yeti and generator on the back and head out. 45884
by: Bret07/31/2018
Product looks and feels very solid and well made. Only took me 5 mins to install. Can't wait to see how it performs as we head out in the next few days. I will be carrying my generators and gas and kids bikes on it. Thank you again etrailer.com for an easy purchase with all of the info i could ask for on your website to help make the best selection for my needs. 548231

Works great used on trailer bumber for portable refrigerator to carry on cargo unit. Had to beef up bumper with angle iron due to weight ...no bounce at all with hitch 457720
by: Jim W.06/03/2013
Receiver bolts right up perfectly to my travel trailer 4'x4" steel bumper. My bumper has a decorative aluminum cladding, but this unit fit just fine over it. This product appears pretty robustly built. In photo this unit looks alot like the much cheaper UF35-946401 (I know because I initially purchased that one, but the u-bolt snapped, so I exchanged for this one). This one is more heavily built, and designed for actual towing. I wanted the peace of mind the heavier product offers. I plan on using to hold a 2 bike platform type carrier. It appears to hold the rack quiet securely. Have not tried it on the road yet, but have no reason to believe it will not perform. 83136

We needed a receiver for a bike rack that would fit the bumper of a travel trailer we have. After reading some of the reviews for this item decided to purchase it. It came within a few days of ordering it as promised. It is held on the bumper with U-bolts that fit the bumper perfectly, and tightened with nylock nuts which are better than lockwashers in my opinion. Overall this is a quality product. 144286
by: melvin hedrick08/20/2013
the hitch was ok the u bolts were not good the nuts would not fit and we had to buy new ones seems like that would be something that is checked before shipment 96068
We have had two instances of this happening, and we have been in contact with Ultra-Fab. It seems that some metric nuts had gotten mixed in with the standard nuts that fit the U-Bolts. We will be going through all the units in our inventory and correcting any affected and Ultra-Fab will be checking before they send units out. Of course, we are more than happy to make sure you get the proper hardware that should be included. Feel free to give us a call.

The product arrived ahead of schedule. etrailer upgraded my shipping at no extra cost! It fit on my bumper with very little problem. It was tight because of my chrome covering, but I expected that. I did have to replace two of the nuts that would screw on, and I had wanted to place it above the bumper but the body of the trailer wouldn't let me. I haven't gotten a bike carrier yet, but I wholly expect it to work just fine. I would have given it an excellent but for the bolts I had to replace. 97056
by: Alvin09/28/2015
Purchased for bike rack on our trailer. Receiver tube was mis-shapen and while it would hold some hitches, would not hold the bike rack. Bike rack fits in our car and truck receivers, but not this one. Of course I didn't find this out until after it was installed and got the bike rack firmly lodged and stuck. Will return for credit and will buy locally where I can confirm fit. Service as always was awesome! 228086
by: David h02/17/2018
Hitch was as expected but the lock washers opened before 30# torque was met. Lock washers purchased at local hardware store worked. Also, one nut was not threaded. Ultra-Fab should retest quality control. 476580
by: Alan M04/10/2017
I was researching buying a new or used hitch to somehow weld onto my motor home for our bike rack. IN fact, I had already purchased a used hitch when I ran across this one. I immediately got a refund and ordered this from etrailer. It was fairly easy to install though it was a super tight fit. Functionally, it has been fantastic! I don't think I would ever risk pulling anything with it though it is rated for small trailers. It is however perfect for my tandem bike rack. I am very thankful for this economical and smart solution. 365299

The Ultra fab 2" RV Hitch Receiver for 4"x4" Bumpers is a very well made piece of steel. It fits our Wildwood Trailer Bumper perfectly. It is built so sturdy we have no worries about using it to haul our bicycles. It is rated at 3.5k! 367586
Thanks for the review Ron, but please also keep in mind that an RV approved bike rack should be used, and please make sure the bumper is appropriately for your use.
-- Rachael H - 05/23/2017by: Rich A.07/03/2013
So far it was very easy to put on the Trailer, I used it for a cargo carrier to place a 3000 Honda Generator on the carrier, work great, the next thing I'm going to try is to pull my 2 Waverunners, but I will check the weight first.. 87521
It has worked great, but now I have changed my Trailer and do not need it anymore

Well constructed, very easy to install, negates fabricating or adapting a hitch by taking advantage of existing 4" bumper. 187377
by: cd01/21/2016
Received the hitch adapter early this morning. The fastest delivery time ever. Under 24 hrs. I have unpacked the product and see no damage in shipping. We have ice and snow on the camper now,so will have to wait for warmer weather to install. I am very pleased with the fast service and the product is well constructed,so I have no doubt that it will meet and exceed my needs. Thank you for your attention to detail and followups thru the process. I would be happy to recommend your company to anyone in need of your products. 235943

Hitch mounted perfectly to the rear bumper of a camper trailer only problem was that the bumper of the trailer was not strong enough to hold the generator I planned on transporting the hitch is fine good quality well-put-together would buy again 567863

Installed on Al clad bumper on our 26' motor home to hold a cargo carrier. Works great but needs shims to keep from moving around. Other than that I would recommend this unit. 544620

This is just what I have been looking for. It's well built and sturdy. Couldn't have found anything better. 542825

Excellent fit - good quality parts - good pricing - installed in 5 minutes with 3/4" socket. Now waiting for the motorcycle ramp to see if the bumper is strong enough! 604335

I haven’t had a chance to use this yet, but the customer service was outstanding! Greg answered all of my questions and helped me find the best product for the best price. I was very pleased with the entire process from the intial phone call to the follow up after it was delivered! 601699

I looked over the internet and 3 RV sales and repair locations in my home town looking for a way to mount my spare tire in any place other than underneath. I am truly grateful that I stumbled onto this website. The Ultra-Fab motor home trailer hitch receiver is every bit the quality that was stated in the website. I can use this to mount my tire and still have my hitch receiver to pull my small car. The strength and quality is incomparable to anything I've seen. You won't be disappointed. `BarryC~ Cullman, Al 599759

Worked perfect . Mounted upside down on my rv bumper for a bike rack. Worked prefect. Leaving in two days so I paid extra for three day shipping. It was here before noon on the third day 591787

by: Robert11/06/2018
Seems to work on our fifth wheel, our factory bumper is very close to the body, this hitch worked. The product could be better if the receiver tube were longer with a second receiver hole to mount our bike rack deeper, it seems to be hanging out a bit. 580692
