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.

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

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

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

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

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

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

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

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

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

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

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: 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

( WOW ) What a great company. They had my item shipped so fast it was unbelievable. I ordered it Thursday afternoon & it got here Saturday afternoon. High quality product to say the least. They upgraded my shipping & were glad to get my business. These people are old fashioned & believe the customer is first. I was very happy & will buy again. 510962

My parts arrived in good order and are well made. I was very happy and impressed with the customer service after I ordered the wrong part, the return was very easy. They even expedited shipment of the right part after I reordered. It was a pleasant surprise to deal deal with a quality company that has such outstanding customer support!! 222408
by: Chuck T03/04/2015
A very well made product at a nice price! Works very well on the bumper of my travel trailer for my tailgating BBQ, The people at - etrailer - were so very helpful and knowledgeable on what I needed! I have been coming back as a customer to - etrailer -since 2010 because of great products, nice prices, and the best customer service!! 176930
by: Paul P.04/22/2015
Well constructed, very easy to install, negates fabricating or adapting a hitch by taking advantage of existing 4" bumper. 187377
by: JC Morris03/16/2017
Very good quality easy and quick to install and heavy enough to carry what I need to carry. 353499
by: Evan05/19/2015
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
by: Henry12/06/2017
Bought this but it was no good for our trailer because our trailer bumper was too weak. Had to have a professional welder create a 2” receiver on our trailer.$350 cad. The welder said he’s seen more of these fail, at best they are ok for solid steel bumpers and should be welded on. 457766
by: Donald S.06/27/2017
The Ultra Fab 2" Hitch receiver and the XC2 Bike rack are both exactly what I needed to haul my bikes when I go camping. It is attached to the bumper on my camper which is welded to my camper frame. The service was great and very quick shipped. Thank You so much 399531
by: Patrick05/03/2018
Just right to tow my little aluminum boat behind the camper ! 503844
by: Matt09/20/2017
Mounted the hitch to the back of our camper today and it works great. I loaded a bike rack and it functioned perfectly. Thanks to Jameson C for suggesting using 1 inch spacer to fit the bumper, resulted in a nice tight fit. Your staff are very helpful. 434519
by: Sammy R.07/24/2015
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: Kevin S01/28/2015
Although I didn't pay for expedited shipping, they upgraded it anyway. I haven't used the product yet, but it is exactly as described. It appears to be a quality built product. Thanks Etrailer for everything. I WILL be doing business again with you. 171535
by: Ron C.04/14/2017
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.

Looks well made. Advertised as able to tow trailers-use caution as it is only bolted to the bumper. I plan to use it for a cargo carrier adapter. There is a cheaper very similar pictured one that is actually MUCH lighter duty. Be careful. 117390
by: Steve R12/06/2016
This hitch and cargo carrier are exactly what I needed and was delivered a day early. I have a small 20' camper trailer. These products are going to make this summers dirt biking trips more organized and enjoyable. Thanks etrailer! 323922
by: Brian J05/11/2012
I am a little disappointed about this Hitch. It is a very loose fit for the receiver. Lots of movement. It should be fabricated to have a better snug fit to eliminate so much play. Other than that it fits the 4" bumper great 40053
by: Robert G.12/01/2017
Very sturdy attachment. Fit perfectly on the trailer bumper and hardware was 1/2" Grade 8 Cad plated--good stuff. Order was received at my driveway exactly on schedule. I would continue to do business with etrailer. 456471
by: Matthew, Calhoun, GA04/06/2015
Very sturdy product. Purchased it with the Maxxhaul Platform-style 2 bike carrier, and it all fits perfectly. Installed the receiver on the camper this weekend and will take it all out for maiden voyage next weekend. 183507
by: storm07/10/2017
I use it to hold a hitch haul that caries a generator and 2 5 gallon fuel cans one gas one diesel I put it on a 25 foot tailor that i some times use to go into the back country it really works well I love it. 403930
by: joatmon05/26/2015
This hitch accomplished exactly what I wanted to do. I had to modify my trailer frame a bit to accommodate it, but that has nothing to do with the hitch. Karen at etrailer was most helpful. Thank you Karen! 196945
by: Neil S08/23/2013
Product as delivered was very stout,,,looks like it will certainly do the job,,,,,, the Lock nuts sent were not right, sent metric instead of the 1?2 inch however the company has mailed them out to me,,,,, 96560
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: William06/17/2018
Easy and fast order and delivery. Quality product. Great customer support. Easy to install. I will use for cargo carrier mounting. Shipping was slightly high but fast and on time. 522845

Ordered this product to haul my family's bikes on the back of our travel trailer. It installed easily and works perfectly, I was pleased with the quality of the product. 145961
by: Vincent04/23/2016
Thanks George for following up. The product is great. Had no problems installing and using and the quality is excellent. Customer service is great also. Thanks again. 246660
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.

by: Michael S.05/28/2014
This will work out great. Now I can put the bikes on a rack off of my 34 foot camper . This leaves room in the back of my truck for other items. Thanks. 132971

I am using two of these to support a generator on the back bumper of my camping trailer, makes a secure mount with less vibration and easy on and off. 389246
by: David B.06/25/2016
This product worked great. Easily mounted to the bumper of the camper and was pulling my small fishing boat trailer that night. Etrailer is the best! 265079
by: Jim M02/24/2015
This hitch is exactly as advertised. Very sturdy and easy to install. I pull my bass boat behind my camper trailer and this hitch is solid as a rock. 175867
by: Mike J03/31/2017
We used this to mount a bike carrier to the back of our 5th wheel. It is well made, no burs inside so the carrier slid right in. Worked perfect. 360874
by: Broncoite07/19/2013
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
by: Mike07/21/2012
This is exactly what I was looking for. The receiver is heavy duty and as long as the bumper holds up, I know the hitch will do the trick. 48788
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
