The B&W Tow & Stow adjustable ball mount lets you tow a variety of trailers with different tongue heights. Having a 1-7/8" ball, a 2" ball and a 2-5/16" ball allows for even more versatility, making this the ultimate go-to ball mount if you own multiple trailers.

Easily Adjusts and Stows

B&W Tow & Stow Ball Mount Operation

To switch the hitch ball, simply remove the pin holding the balls in place and rotate the entire block that the balls are mounted on until the ball you want to use is on top. Then replace the pin to secure the block in place.

Adjusting the height of the ball is just as easy. Remove the pins holding the ball mount platform in place and slide the platform up or down along the shank to the desired position. Once you have found the correct height, reinsert the pins and replace the clips.

When you're not towing, you can flip the ball mount platform around and stow it beneath your hitch so that you won't bang your shins. Just remove the pins to slide the ball platform down along the channel and up the back side so that the hitch balls face towards your vehicle. Then replace the pins.

Built-In Anti-Theft System

The Tow & Stow ball mount features a channel that runs along both sides of the shank. This channel not only allows you to slide the ball mount platform up and down to adjust the ball height, but it also prevents removal of the platform when the ball mount is installed, which will help prevent theft of your trailer.

Single Dimensions

A slot is cut into the adjustment channel near the top of the shank. To remove the ball mount platform from the shank you will need to remove the entire ball mount from your hitch. Then remove the pins that hold the platform in place. Flip the platform around to the stowed position on the rear of the shank, and then slide it up until the center pin lines up with the slot in the shank. Pull the platform out towards the rear of the shank until the pin pops out of the adjustment channel.

When the Tow & Stow is secured in your hitch receiver, you will not be able to remove the ball mount platform. This is because the slot in the shank is positioned in such a way that the collar on your hitch will block the pin on the platform from being able to leave the channel. Even if the pins holding the ball mount platform in place are removed, the platform will still be confined to this channel. So, as long as a hitch lock is used to secure the entire ball mount in your hitch receiver, and a coupler lock is used to prevent your trailer's coupler from being disengaged from the ball, your trailer will be secure.

This hitch is stellar, extremely well designed, built and made in the USA which is very important to me. I can't wait to pull with it!


Absolutely wonderful! Super heavy duty! I haul around my heavy duty dump trailer with 15-20k pounds in it and this hitch can withstand anything. I have it turned upward instead of downward to lift up the trailer a little higher to help with sag on my truck from the weight. I also love the ability to stow it however I never use that feature cause I’m always towing.


Quality American made hitch. And as always, etrailer is tops with customer service. If you need a hitch like this, I highly recommend this one.


Ordered this hitch for my 2021 F350 Lariat. Perfect fit with perfectly matched ratings to my vehicle capabilities. I REALLY appreciated the brochure that came in the box as it was informative, educational, and concise. Packaged very well and arrived promptly. Thanks guys/gals.


Looks great. multiple trailers that I have towed,easy to adjust. It is locked on all the time and it is legal.


I originally ordered a Weigh Safe hitch, thinking it would rotate under the receiver when not needed, but it does not. I ordered this B&W that does so perfectly. My garage is barely long enough for the pickup and moving the ball into stow position prevents me having to remove it every time I pull into the garage. It would be too easy to be stolen if left loose in the back and in case if an accident I wouldn't want that hitch flying around inside the cab.


I have a 2017 F350 4X4 with factory 20 inch wheels and no lift. I used several videos to help determine the amount of drop that I needed. I went with this hitch. It was delivered quickly. The box was a little "ratty" looking, but the hitch was not damaged. I installed the hitch easily and to my surprise there was less play than I had expected. I had to use the lowest drop setting to get the tongue of my trailers level.
Their description advises that you have a minimum of 11 inches from the bottom of the hitch to the ground/road. This hitch is "comes in" at just 11 inches of clearance. The stow & go feature also worked well. It is a little aggravating only because the hitch is heavy, which is a good thing. I made a short pull (unloaded) and there was minimal noise in the receiver. That can be eliminated with various solutions. The trailer pulled very well with no issues. So far I am pleased with my purchase. e-trailer also had the lowest price, as I was given a 5% discount...Thanks for that. I looked at numerous places/sites.


I have pulled serveral trailers and had no issue. very easy to change ball setup and hights. love it


This is the second time I have ordered something from etrailer. Both experiences have been extraordinary both in sales and delivery. The sales people who took my order were helpful and took extra care in making sure I got the best service. Their follow up and follow through after the sale will keep me coming back. The products have been top of the line. Excellent company.


Haven't utilized it yet but it's exactly what I was looking for in a hitch, strength and versatility.


Just received my B&W Tow & Stow 3-Ball Mount - 3" Hitch - 7-1/2" Drop, 7" Rise - 21K - Black, and I am so thrilled about the product. The ordering was easy and it came to my house fairly quickly. They keep you up to date with what is going on, with your order, and that is fantastic. It completes my new Ford F250 LIMITED. Thank you!!


I had been in the market for a hitch for a long time. Came across this one on this website and it has fulfilled all the requirements I need for my towing needs. The hitch was immediately shipped and communication with etrailer was fast and satisfactory.


Good heavy hitch shipping was fast the only problem I had was the powder coating was chipped and scratched a little bit


Very stout. Quality. Don't drop it on your toe. Fast shipping. Paired with a good lock.

Great. Also ordered the draw bar for pulling implements. No more removing my hitch for other trailers.

Great hitch well made and heavy duty

Fantastic I love it best hitch Ive ever owned
Emory - 07/17/2022


After a year I like it better every time I use it. It cleans up the back when not is use, and then quickly converts when you need it. I pull all sizes of trailers so the easy spin selection of ball size simplifies connection. Pins were tight at first but a light sanding and use solved that.


WOW! nice hitch. Installed on a 2022 F250 Platinum. For all of you that are wondering, 11.25" to the bottom of the hitch when installed.


Tough product, had the 2inch one. This is their 3” receiver!


Awesome quality at its absolute best!!!!


The service I received with a trailer is second to none. I will always go to e trailer first.

Thank you for providing such great service and products.


It appears i was not the first one to receive this hitch. Look like it has been thru a small war. BW sticker half off and markings on the hitch. I guess it will get banged up anyway so i will live with it.Too much trouble to send back.

Customer Service will reach out to you.
-- Etrailer Expert Sierra K - 10/21/2021


My order was out of stock. E trailer notified me right away with an alternative. I called and receive a great description of the in store alternative. The parts will be shipped right away. Unbelievable customer service!!!


It works as described. I did have some issues on the product received, however the etrailer customer service is great, I mean it is GREAT! They made everything right! They do what they say!


Solid performer and simple to use.


Well built!

See what our Experts say about this B and W Trailer Hitch Ball Mount

  • Does Ball Platform of B and W Tow n Stow part # BWTS30049B Require Locks
    Actually the B and W Tow n Stow part # BWTS30049B that you have has a locking mechanism built into the channel which would prevent the platform from getting removed. This is because the slot in the shank is positioned in such a way that the collar on your hitch will block the pin on the platform from being able to leave the channel. Even if the pins holding the ball mount platform in place are removed, the platform will still be confined to this channel.

  • Can 3" Accessory Fit With Smaller Hitch Receiver Opening
    Your 2017 Chevy Silverado 2500HD will likely have either a 2" or a 2-1/2" trailer hitch receiver. You can confirm this by measuring the inside height and width of the receiver on your pickup (see attached). If you are trying to use a 3" accessory in a smaller receiver then there unfortunately aren't any adapters that work for your application. If you do have a 3" receiver then yes, you can use an accessory with a 3" shank, like part # BWTS30049B. If you are referring to something different...

  • Compatibility of B&W BWTS30049B Tow&Stow Adjustable Ball Mount with 2020 Ford F350
    The # BWTS30049B Tow & Stow ball mount is designed for 3 inch hitches, like what your 2020 F350 is equipped with. The upright or vertical portion of the B&W # BWTS30049B Tow & Stow adjustable ball mount is about 11 inches in total. If you measure 11 inches down from the top of the receiver tube of your F-350, you'll have a pretty good approximation of where the bottom of the ball mount would sit.

    The B&W Tow & Stow 3-Ball Mount - 3" Hitch - 7-1/2" Drop, 7" Rise - 21K - Black # BWTS30049B will not interfere with your rock tamers. From the hitch pin hole to the nearest point on the ball mount is 9-1/4 inches. This will give you plenty of space.

  • Tongue Weight Capacity of B and W Tow n Stow Ball Mounts # BWTS30049B
    The tongue weight rating of the B and W Tow n Stow Ball Mounts like the part # BWTS30049B is based on the ball that you use. Basically each ball has it's own weight capacity and the tongue weight capacity is 10 percent of the trailer weight rating listed. So for the 1-7/8 inch ball you'd have a 350 lb tongue weight capacity, for the 2 inch ball it would have a 750 lb capacity, and for the 2-5/16 inch 2,100 lb.

  • Which B and W Tow & Stow Adjustable Ball Mount for 2021 Ford F-350 with 3 inch Hitch

  • Best B&W Tow and Stow Ball Mount for a 2022 Ford F-350
    I would be happy to help you find the right ball mount for your husbands birthday. You are gong to need to measure the receiver on the end of his F-350 to determine the correct ball mount you need. You will want to measure the inside of the square. It should be 3' x 3" or 2.5" x 2.5". The B&W Tow & Stow 3-Ball Mount item # BWTS30048B you were looking at fits a 3" hitch. Which means it would need a receiver that measures 3" x 3".

    Yes, the I Hitch Lock # AM3492 that you referenced is compatible with the platform adjustment pins of the B and W Tow and Stow ball mount # BWTS30049B. It will lock the platform portion of the ball mount to the shank and the ball to the side brackets. these aren't required by the design of the hitch as the ball platform can't be fully removed without removing the entire ball mount from the receiver.

  • Ball Mount Recommendation for 3" Hitch Receiver on Ford F-450

I recommend using the Weigh Safe Hitch Receiver Lock for 2", 2-1/2", and 3" Hitches - 3-1/2" Span # WS05 which is that 5/8 inch pin designed to secure this ball mount. The B&W Tow & Stow 3-Ball Mount - 3" Hitch - 7-1/2" Drop, 7" Rise - 21K - Black # BWTS30049B also has the 5/8 inch diameter hitch pin hole, so I recommend using that same lock. The Draw-Tite Super...
