An illustration shows the eleven inch clearance level needed between the ground and B and W Tow and Stow hitch.

Note: To avoid the Tow & Stow hitting steep driveways or curbs, we recommend at least 11" of clearance between the ground and the lowest point of the drop hitch, as seen above.


The B&W Tow & Stow adjustable ball mount lets you tow a variety of trailers with different tongue heights. Having both 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.

I needed a drop hitch and I wanted to get rid of the two sleeves that rattled and made it hard to line up the pin holes. This took care of both, and I have a heavy-duty ball mount that I will never wear out. I run all B&W products, it is top of the line equipment and E-tailer is a great company to deal with.



by:

Looks great in any position! Hopefully get an update after hooking up my trailer.

Best hitch I have purchased

Still one of the best hitches ever purchased we use both of them everyday. No rust rotate freely. Will definitely purchase again for new vehicles

@Ray We're happy to hear that your B&W # BWTS30037B Tow & Stow ball mount is still working well for you!


by:

As always etrailer came thru with a great product, outstanding customer service, timely shipping with great pricing. They are my go to for trailer parts.



by:

etrailer shocked me with their customer service. The B & W trailer hitch I ordered was out of stock. Within 10 minutes of placing my order at 10:00PM an employee contacted me to make sure I knew it wouldn’t be back in stock until the following week. And also took the time to add links to two different B & W hitches that are similar in case I needed it immediately. Unfortunately that kind of customer service isn’t expected anymore, it really made me feel good. I run several trailers for my business and they earned my business from now on.
As for the product itself, exactly as expected. Price was right. And no more swapping between 2” and 2 5/16” hitches. My shines will also appreciate this hitch when walking behind my pickup in the dark!



by:

I received the mount yesterday, greased the pins and installed on my 2017 F350 Powerstroke FX4. The quality is certainly impressive and the powdercoating is pristine. Even the stickers are stuck on straight! I am very happy with the overall fit and finish - this is how I would want my product to look if I was B&W. The thought of installing/uninstalling a ball mount every time I needed to pull a trailer loses its appeal when they are rarely where you need them or where you think they are. I researched a number of options - cushion mounts, etc. - and there are only a handful of 3" ball mounts out there right now. I didn't want to have to worry about the factory adapter sleaves in my receiver either. This addresses all of those concerns perfectly. It's out of the way when I am not using it and right there if I need it. Frankly, I cannot imagine a better solution to the problem. Yeah, it's a big hitch despite being the smallest offering in the 3" category, but I don't anticipate handling it too often. The only downside I see is that there are no drawbar mounts or silencers offered for the 3" version and there do not seem to be any locking pin options to replace the 3 stainless pins that are just held on with pin clips. I am hopeful no one uses my mount to scavenge for missing parts on their own mount. The locking pins would need to be 5/8" diameter with a span of no less than 4 5/8".



by:

Hitch arrived as scheduled. Excellent product, exactly as advertised. Normally tow a fifth wheel and had great confidence in B&W. Need to tow a utility trailer and this is perfect!



by:

I needed a ball mount for my 3" reciever. I found what I needed at etrailer and for the best price! Thanks.



by:

This hitch is very heavy duty and provides great pulling for all of our different trailers no matter the load.



by:

As with any B&W product it’s great. Also think it’s great that etrailer reached out after a year for a review and not the next week when you have no clue how something truly performs.



by:

The item I oreded was shipped and arrive before the scheduled delivery date. The hitch came with easy instructions and was exactly what I needed. Thanks for the quick response and delivery.



by:

Great hitch with the added feature of storing when not in use. This storing feature allows the hitch to serve as a bump stop to keeps cars from going under your truck (when they are texting and driving).



by:

Great service and a great product!



by:

Wonderful Product I bought one fro all my trucks!



by:

Very heavy duty! Cant wait to try it. As described and fits nice and tight in the factory ford super duty 3" receiver



by:

Best hitch you can buy for the 2017+ F350’s. No more sleeves, no more rattling hitch. Best hitch I’ve had.



by:

Extremely disappointed. This is supposed to be a top notch ball mount and the packaging was HORRIBLE! I had to clean the thing up from top to bottom before I even thought about mounting it to my 2021 E450 Super Duty. I chose black to match my blacked out truck and now I need to paint the thing.

You mentioned you needed to clean the ball mount and I wanted to ask a few questions. Would you be able to send pictures of the ball mount? What was on the ball mount that it needed to cleaned?

Rod

1/19/2022

Unfortunately I could not stand it and cleaned it immediately. The whole contraption was covered in dust as if it had been on a shelf for years. I didnt get it spotless but I doubt pictures would pick up whats left. Thank you for caring.

I will have our customer service team reach out to you.

Fast shipping, exactly as described.

I
have been purchasing from Etrailer for years. From small parts to axels and tires, Always polite and courteous on the phone if I call with a question.



by:

The hitch is just as sleek as advertised when folded back. And with a 21K tow capacity its hard to believe it can be so compact from the heavy hitches I used to have.



by:

Website yo order from was easy and received my order within 2 days



by:

This is the second item I have ordered from etrailer. The first was a FW hitch. Both times, the process has been smooth and easy and the delivery was fast! Great online sales experience. Will buy here again!



by:

Just want I wanted and came earlier than expected with backlog. Pricing was better than the other online provider and they reached out knowing it was back ordered to offer another option.



by:

Very high quality. Simple and easy to switch ball sizes.



by:

Have four of these needed new one



by:

Heavy duty is what this thing is. I love the tow n stow feature. Very easy to change the hight or flip it to stow.

  • Does B&W Make a 2-Ball Ball Mount for a 3 Inch Receiver
    B&W does indeed offer a Tow & Stow 2-ball mount for a 3 inch receiver. Part # BWTS30040B includes a 2 inch and a 2-5/16 ball, and is adjustable up to a 7-1/2 inch drop or a 7 inch rise.

  • Can I Replace the Ball Mount of a 3 Inch B&W Tow and Stow for a 2-1/2 Inch Ball Mount?
    No, you can't. I contacted B&W this morning and was told they do not sell the components of their tow and stow ball mounts separately. While you are most likely correct and they are probably interchangeable, B&W wants you to buy a new one. It sounds like you have either item # BWTS30037B or item # BWTS30040B.

  • How To Convert 3 Trailer Hitch Receiver To 2 To Use Bike Rack On 2021 Ford F-250 Super Duty
    The Trailer Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # e33YR will be your best option for reducing your 3" receiver opening down to 2-1/2" or 2". Then you can install Malone 2" Dual Purpose Hitch Receiver # MPG544 to drop the receiver down for the bike rack to sit lower to the ground. Keep in mind, this reduces overall receiver capacity by 50%, but that shouldn't be an issue on a truck of this size. You can use B and W Stow and Tow Dual Ball Mount - Model 8 - 2" Ball and 2-5/16"...

  • Is It Normal For The Redarc Tow-Pro Liberty to Barely Brake When Using Manual Over Ride?
    That is the way the Redarc Tow-Pro Liberty Brake Controller # RED52VR operates. This is one of the few controllers which only lightly activates the brake output when pressing the manual over ride. Redarc does offer their Tow-Pro Elite # RED44FR which allows you to switch to the user controlled mode which will give you more output to the brakes when using the manual over ride in this mode.

  • Locking Pins for B&W Tow and Stow To Fit a 3 Inch Receiver Tube
    The B&W Tow & Stow 3-Ball Mount only needs one hitch pin lock, part # WS05 if you have a 5/8" hitch pin hole. The reason for this is that the hitch balls on the B&W Tow & Stow Ball Mount cannot be removed with the ball mount in the receiver tube due to the integrated channel. Therefore, it is not necessary to have locking hitch pins in the adjustment holes.

    So there is a B&W Tow & Stow that fits a 3 inch hitch and has a capacity up to 21,000 lbs, but not with a pintle hook. I checked directly with B&W to verify this for you. The 21k capacity is for the included 2-5/16" hitch ball, and if you were okay with that, you can choose from the following, depending on the maximum rise or drop you need: - Max 4-1/2" Drop, 4" Rise: B&W Tow & Stow 2-Ball Mount - 3" Hitch # BWTS30037B - Max 7-1/2" Drop, 7" Rise: B&W Tow & Stow 2-Ball Mount - 3" Hitch...
