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.

  • Is There a B&W Tow & Stow For 3 Inch Hitch With 21,000 lb Capacity
    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...

  • 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.

  • 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"...

  • 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. The comparable 2-1/2" Tow and Stow two ball ball mounts are listed below: B&W Tow & Stow 2-Ball Mount - 2-1/2" Hitch - 7-1/2" Drop/Rise item # BWTS20040B B&W Tow & Stow 2-Ball Mount...

  • Can B&W Tow & Stow For 3 Inch Hitch Have Holes Drilled Into It
    No, you definitely cannot drill a hole in the B&W Tow & Stow 2-Ball Mount - 3" Hitch - 4-1/2" Drop, 4" Rise - 21K # BWTS30037B. You'll need to use a standard hitch pin or lock such as the Draw-Tite Trailer Hitch Lock w/ Pick-Proof Key - 3" Hitches - Flush - 4" Span # 63260.
