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 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.

Stow the ball and mounting platform on this tri-ball ball mount beneath your hitch for a sleek look when you are done towing. Tow up to 3,500 lbs with the 1-7/8" ball, 7,500 lbs with the 2" ball, or 21,000 lbs with the 2-5/16" ball.


Versatile, heavy duty hitch. I love the ability for it to change from one need to the next without a bunch of fuse. And, then when not needed it will fold out of the way.


Would probably rate higher but I have not needed to use either tow package yet. Seems good, looks great, pretty straight forward to install.


This hitch is amazing !I tow trailers for friends and family alot ,and now I only have to carry one hitch .Being able to leave the hitch in and not smash my knees ,is a really cool feature .


Looks very sturdy and adjusts easily. Also made in USA


Heavy duty hitch. Only issue was it is a very tight fit into the receiver.

Great well made product but high quality has a high price. $$$


Fantastic Hitch! Very well designed. Super Strong and Easy to Adjust with Excellent anti theft Features. Love this Hitch!! Highly recommend it!!


Order arrived quickly and etrailer communication was great. The only small niggle I have is that the box was open as the heavy duty copper box staples were detached, so I must have received a unit that somebody else had returned. However, all pieces are present and the unit is in good condition, so I’ve already mounted it to the truck and it looks great. Hopefully it will deter people from rear-ending me - which was one of my motivations for getting it!


Excellent product. Hot just right.


Great quality with rapid shipping


fits and works great. convenient having three different ball sizes on one receiver.


Good product but it should be sold with locks on the pins


Hitch is great and what expected.


I love the product and have owned a few B &W hitches. The only negative about this one was my wife bought it for me and didnt know the difference but purchased one that fits a 3/4 ton truck and not my half ton truck. Even with this I will be buying more B & W hitches, only I will be purchasing them myself.


Heavy duty, easy to use.


Nice hitch, a little sloppy tolerances. Definitely pinch points when adjusting the ball height and stowing. Count your fingers before and after.

The fastway hitch locks will work on the receiver, but not long enough to replace the pins on the ball adjustment.


Super fast, great communication, great price.


Great quality. Shipped fast. Excellent service overall


Fast shipping and well packaged.B&W hitches are top notch. I would definitely recommend to a friend.


Very quick service and got it right!


I have had this for over a year now and use it on a regular basis with the F350. It stands up to its reputation and is as sturdy and reliable as I could have hoped for. Highly recommended!!


Purchased for eldest son. Expert handling by all staff I encountered. Great product made in the USA.


Haven't used it yet just arrived today seems well built, made in the USA a definite plus


I Received my Hitch quickly. That thing is a TANK ! It is sturdier than I expected. It is highly adaptable. I can tow anything that mounts to a bumper


I have a F250, and the 4 1/2 inch drop works fine.

  • Does B and W Tow&Stow Adjustable Ball Mount Affect Turning Radius
    The B&W Tow & Stow 3-Ball Mount # BWTS30048B that you referenced does not affect your turning radius. The balls that are on either side would be too low to cause any interference.

  • Tongue Weight Capacity for B&W Tow & Stow 2-Ball Mount part # BWTS30048B
    The tongue weight (TW) capacity of the B&W Tow & Stow 2-Ball Mount part # BWTS30048B will be 10% of the gross trailer weight (GTW) capacity for the respective hitch ball. So when you use the 2-5/16 inch hitch ball you'd have a TW capacity of 2,100 lb, when using the 2 inch ball 750 lbs, and when using 1-7/8 inch ball 350 lbs.

  • Will the Hitch Pin Hole On B&W Tow & Stow 3-Ball Mount Fit a 2021 Ford F-250 with 3" Hitch
    The trailer hitch pin hole on a 2021 Ford F-250 Super Duty should be the standard 5/8" diameter. Since you have the truck, I recommend measuring to confirm. Therefore, the B&W Tow & Stow 3-Ball Mount part # BWTS30048B would be a great option since it also uses a 5/8" diameter hitch pin hole.

  • Will the B&W Tow & Stow 3-Ball Mount fit 2020 Ford F-250 Super Duty
    The B&W Tow & Stow 3-Ball Mount - 3" Hitch - 4-1/2" Drop, 4" Rise # BWTS30048B will fit your 2020 Ford F-250 Super Duty as long as you have a 3" hitch. This also has a maximum drop of 4-1/2" and requires 11" from ground to the lowest point on the Tow & Stow. Without the minimum 11" clearance the hitch may hit the ground or other objects such as steep driveways or curbs. I have attached a review video for your reference.

  • Best B&W Tow and Stow Ball Mount for a 2022 Ford F-350
