Average Customer Rating:  4.7 out of 5 stars   (378 Customer Reviews)

I’m using this receiver a little differently than it’s intended purpose. After getting some longer bolts and drilling holes in some aluminum angle stock, I mounted it to the tongue of our trailer. Now I have a place to store the head of our weight distribution hitch when it’s not on the truck. I just slide it into this receiver and it’s up, out of the way instead of taking up room in a storage compartment or sitting on the ground. I have a locking hitch pin I can use for added security. A simple and cheap fix.




by:

I've used this to attach an aluminum basket as well as a bicycle carrier. It works perfectly




by:

I ordered and received two of these hitch receivers and installed them on the rear bumper of my camper to carry my 150 cc scooter. Shipping was great and parts mounted without any problem. All hardware was included and fits perfect. Have purchased other items from etrailer previously and look forward to additional items in the future. This company is great to deal with.


Comments
Did you end up having any problem with the weight of the scooter breaking the bolts..? I am buying 2 to do something similar...making a carrier for my generator and plan on using 2 hitches...
-- comment by: Mark H - 08/24/2015
No problems at all. Used it several times already and works great. I mounted them at the frame extensions.

by:

Overall pretty good. four stars because I added jam nuts to the anti-wobble screws.




by:

I looked at several options for attaching a bike rack to my camper and this was what I wanted. I looked at several similar items on Another online retailer that had complaints about the receiver falling off because of faulty welds. I am quite certain that this product won’t come apart, in fact, you could probably pick the whole camper up by it. It is built like a tank, and is incredibly easy to install. It was more expensive than the junk on Another online retailer, but I won’t be worrying about my bikes falling off going down the road




by: 10/04/2022

well built wouldn't work in my application would work good on square tube applications in my opinion




by:

The unit looks like it is of good construction but when I went to put it on the bolts are too short not the u-bolts but the other two. No way to make them work. Going to hardware store to buy longer bolts for assembly to work.




by:

Fits great on the 4" bumper on our motorhome. Seems very sturdy and should work great for our 2 bike rack, without interfering with the trailer hitch.
I'd probably give it 5 stars, just haven't gotten to use it yet.




by:

I have not installed the product yet, but I have a complaint. All the advertising material said to limit the load on the product to 200 pounds. The installation instructions that came with the product said, no matter what, do not exceed 100 pounds. The product looks as represented and I will install it later today.


Comments
I contacted the manufacturer to be sure about the tongue weight and they said that it used to be 200lbs but they recently changed it to 100lbs. I apologize for this inconvenience and we are currently updating our site to reflect the new tongue weight.

Ise this item on my travel trailer to keep my hitch out of the way,off the ground. Love it to store it so I don’t kick it on the ground.




by:

I placed my order and had my part within a week. Now we can take our bikes with us wherever we go. Just moved the spare tire over and bolted the reciever right on. Thanks guys.




by:

This product was very easy to install and will be perfect for holding our bike rack. Very heavy duty for the price, excellent quality.




by:

Very happy with the product we purchased for our RV. It fit perfect, and now we can transport our bicycles when we go camping! Now we don't have to take up space inside the RV or the back of the truck!! See attached photos.




by:

This was the product I needed to store an accessory from my truck on my fifth wheel camper bumper while not in use. I actually mounted this "vertical" to store my motorcycle carrier "out of the way". I could see mounting this normally to carry light weight accessories while trailering my fifth wheel.


Comments
After a year, product is still what I wanted and doing what I needed. Actually moved to a new fifth wheel in December and brought this forward to the new camper. Very handy!

Planning to use to take my bike with me when camping. Mounted very easily. Did not read installation instructions before purchasing and missed the fact that it distorts the bumper. Got my waste hose fitting stuck on the distortion. Resolved, but wish I had seen ahead of time in description. No issue moving forward.




by:

I received this product and immediatley installed on my camper bumper, while installing I found two of the 4 lock nut would not screw on to the "U" bolts provided. I then found two of the same size nuts in my toolbox and completed the install. After inserting the bike carrier one of the "U" bolts broke off, It looks as if the "U" bolts are made of a cheap material.I had to purchase a "U" bolt from the local hardware store to replace the broken one. I don't know if I would recommend this to anyonebecause of the faulty "U" bolt.


Comments
After replacing the cheap U bolts with new ones, so far the product is work well.

Thank you
Received my bracket on time,
great quality, easy to install, exactly what I was looking for.
Recommend this bracket to any RV person wanting to transport bicycles. Receiver is perfect for my Yakima bike rack...


Comments
Its Great! Thank you....

by:

The trailer hitch is very sturdy and well built. The only problem, which was not really a problem, was that it had to be mounted upside-down due to how my trailer body is built. Also, one nut was missing in the package and I had to replace it with a nut from my garage. This is being used for bicycles and worked very well. The extra supporting bolts held very well and the hitch did not come loose at all on my 1600 mile journey.




by:

Exactly what I ordered and on time. E trailer is where I go to get stuff for my camper.




by:

Hi,
I was driving back home after our
vacation and utilizing the bike rack, along with the hitch receiver, and adapter bars. 1/2 way through Nebraska, a Mustang pulled up while i was driving and yelled, "do you have a bike rack?" I said yes, and he yelled it had fallen off!

This was on interstate 80 going 70 mph. I pulled over, and the rack was gone. So we drove to the next exit and back tracked. I was just hoping nobody was hurt. About 7 miles back, we saw the bikes on the side of the road still attached to the rack. We went to the next exit, turned around, came back and gathered the bikes and real with the help of a state trooper. After looking at the rack, i could see it was still attached to the receiver i purchased, but the u bolts had snapped. 4 damaged bikes due to defective u bolts.

I use this trailer hitch receiver to mount my bike carrier on the bumper of my travel trailer. I carry up to four bicycles and this hitch performs beautifully. It is heavy duty and easy to install.

See what our Experts say about this Ultra-Fab Products RV and Camper Hitch

  • Mounting Ultra Fab # UF35-946401 Under Bumper
    It is acceptable to mount the Ultra Fab # UF35-946401 underneath the bumper. Make sure the 200 lb capacity of the receiver or the capacity of the bumper (whichever is lower) is not exceeded. This receiver is meant to mount to a 4 inch Steel RV bumpers, and not to a car or truck. It is not intended to be used for towing purposes.

  • Receiver Size of Ultra-Fab 2-Inch Bumper Mount Hitch # UF35-946401
    The Ultra-Fab 2-Inch Bumper Mount Hitch, part # UF35-946401, is only available with a 2-inch receiver opening. All of the RV bumper mount hitches will have a 2-inch size receiver opening. Trailer hitch receiver sizes are available in three different sizes, 1-1/4 inch, 2-inch, and 2-1/2 inch. The two most common sizes would be the Class I and Class II 1-1/4 inch, and the Class III and Class IV 2-inch. The Class V 2-1/2 inch size is used on heavy-duty trucks. I am including a link to a...

  • Installation of a Ultra-Fab 2-Inch RV Trailer Hitch Receiver Part UF35-946401 on a 4-Inch Bumper
    You are correct. The Ultra-Fab 2-inch motor home trailer hitch receiver # UF35-946401 is designed to bolt around a 4-inch RV bumper and the receiver opening will be on the topside of the bumper. This receiver is designed for mounting accessories like a bike rack, and not for towing purposes. It has a 200 pound capacity. Make sure you do not exceed the weight rating of your RV bumper. So if the bumper has a lower weight rating, you will want to go by the lower weight rating.

  • Installing Ultra-Fab # UF35-946401 Bumper Mounted Receiver on 2 x 2 Pipe Bumper on RV
    When you describe a 'pipe bumper' do you mean that its round, or is constructed of square tube? If it's a round pipe, I wouldn't recommend attaching a receiver to the bumper as any tongue weight (downward force applied to the receiver) would rotate the receiver tube downward. If you're talking square tube, the Ultra-Fab # UF35-946401 wouldn't be your best option as the threaded portion is about 1-3/4 of an inch long. It wouldn't cinch tight enough, plus the spacing between the legs of...

  • Why Cant the Bumper Mounted Hitch Recevier UF35-946401 Be Installed on Decorative Bumper Cover
    The Ultra-Fab 2 Inch Motor Home Trailer Hitch Receiver # UF35-946401 is not designed for use on decorative aluminum bumper covers because the installation of the receiver and the weight of the accessory used in the receiver would likely damage the decorative aluminum cover. When the bumper cover becomes damaged, the receiver would no longer be installed securely enough on the bumper and could move while a hitch accessory is being used.

  • Bumper Hitch that Can Fit Bumper of 2011 JayFeather That's 4.5 inch by 1.5 inch
    The best solution we have is going to be the Ultra Fab hitch part # UF35-946401 which is designed to attach to a bumper that is 4.5 inches tall and 4 inches wide. Since your bumper is narrower you'd need to come up with spacers to take up the additional width. I attached an install video for this for you to check out as well.

  • Trailer Hitch for 1995 Chevy G20 Van
    There is a hitch receiver that could work for your 1995 Chevy G20 van, so long as your van does NOT have a step bumper. If so, I recommend the Draw-Tite # 75121 hitch, this is a 2" hitch that is a complete bolt-on installation so there will be no drilling required in your Chevy's frame. I have added a link to a video of this hitch being installed on a '94 van for you to check out so you can see the process involved.

  • Alternate Mounting of Ultra-Fab 2" Motor Home Trailer Hitch Receiver
    I contacted the Tech Rep at Ultra Fab Products, they stated that it can be mounted underneath but they do recommend it on top. The Ultra-Fab 2" Motor Home Trailer Hitch Receiver, # UF35-946401 is designed, tested and weight rated for an installation of weight setting above the bumper not below. Any alternate installation of product is determined by the purchaser with that understanding. They added that if you are going to be installing a bike rack on the hitch, be sure to pay very close...

  • Will the Ultra-Fab 2" Motor Home Trailer Hitch Receiver Work for Motorhome Tire Carrier
    The Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers part # UF35-946401 has a 200 lb weight capacity so as long as the weight of the spare tire carrier and spare wheel/tire do not exceed this you will be good. That said, you also need to take the bumper's weight capacity into consideration and abide by the lowest rated component. There isn't any reason you couldn't use this for a motorhome wheel/tire so long as you be mindful of your capacity.

There was a redesign of this product, some of the photos you are seeing in reviews may be of the previous model. We do our absolute best to keep our product photos up to date with the correct product model. It is important to note that when you use a hitch extender you will be cutting your tongue weight capacity by 50%. While Ultra-Fab may not be as well known to some,...

  • Bumper Mounted Hitch Recommendation for a 2017 Starcraft Satellite 17RB Travel Trailer
    As long as the 4 inch square bumper on your 2017 Starcraft Satellite 17RB travel trailer is made of steel and welded its entire length then you would need hitch # UF35-946402 because it is the model for 4x4 inch bumpers. I have linked a video of this hitch for you. The combined weight of your carrier and the tote tank isn't very much but you will still want to check the trailer literature to make sure that the bumper is rated for carrying weight and. if so, the amount of weight it can handle.

    The only hitch we currently carry that would fit a 73" frame width is the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames Item # UF35-946403. It is a weld on and has a tongue weight capacity of 350lbs. It is not rated for towing. I do not recommend using any bumper-mounted hitch receivers like the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" BumpersItem # UF35-946401 you linked to unless you know the weight capacity of the bumper.

    I attached two pictures that detail where the hitch tube and opening are in relation to the bracket for you to check out. Hitch manufacturers basically refuse to get into the specifics of the hitch extender capacity reduction for fear of people assuming they can carry more than they should based on hypothetical math problems. Hitch extenders though are even more hard on hitches when installed at the back of an RV because trailers have much rougher ride qualities than vehicles. I really...

    Best solution we'd have is the Curt Multi Fit hitch part # 13703 which fits frame widths between 22 and 72 inches apart (outside to outside) and fits all frame styles.

We have the Brophy Hitch Reducer, part # HT02, that will reduce a 2-inch hitch to a 1-1/4 inch size, because it is a sleeve design it will not reduce the tongue weight capacity.

Installation requires that the bumper be fully open in order to allow the U-bolts to attach securely. This hitch is not suitable for use on your 2008 Chrysler Aspen.

    The Ultra-Fab 2" Motor Home Trailer Hitch Receiver part # UF35-946401 has a bolt hole spacing of 5" front to back and 4" side to side so it does not sound like it would work for you. However, we do have the Stromberg Carlson 2" Motor Home Hitch Receiver part # BA-100 which has a bolt hole spacing of 5" front to back and 5" side to side so it does sound like it would work for you although I am not quite sure of the intended purpose.
