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...

  • Weight of Weigh Safe 180 Hitch 2-Ball Mount # LTB6-3
    The Weigh Safe 180 Hitch 2-Ball Mount # LTB6-3 has a total weight (with the ball platform attached) of just 22 pounds. The shank by itself is only 8 pounds. You are right that the aluminum shank allows it to weigh less than all steel options such as the B&W Tow and Stow # BWTS30040B that weighs closer to 40 pounds. I have attached a short video demonstration that you can check out as well.

  • Picking Out Adjustable B and W Ball Mount for 2017 Ram 2500 with 3 inch Hitch
    For your 2017 Ram 2500 that has the factory 3 inch hitch we have a couple B and W Tow n Stow adjustable ball mount options available. We have the part # BWTS30037B which can do a drop of up to 4-1/2 inches and we have the part # BWTS30040B which can do a drop of up to 7-1/2 inches. So to determine how much drop you'd need you'd need to take two measurements. Measure from the top of the hitch opening down to the ground on your truck and then measure from the bottom of the coupler lip to...

  • Recommended Ball Mount for 2017 Ford F-250 with 3 Inch Hitch Receiver
    In order to determine how much drop you need, you will measure from the top inside edge of your trailer hitch receiver on your 2017 Ford F-250 to the ground. Then you will measure from the ground to the bottom of your trailer coupler when it is level. The difference between these measurements is the drop you need. I've attached an article to assist and have linked 3 inch ball mount options. I personally recommend the B&W Tow & Stow 2-Ball Mount - 3" Hitch -7-1/2" Drop, 7" Rise - 21K...

  • Recommended Hitch Lock and Ball Mount Compatible with 3 Inch Hitch with Reducer Sleeve
    The Flash E Series Adjustable 2-Ball Mount w Chrome Balls # FA42-00-2800 has a 5/8 inch pin hole diameter. I believe you will be able to use the Fastway Trailer Hitch Lock and Adjustment Pin Lock Set for Flash E Series Ball Mounts # FA86-00-3660 for a locking combination. The hitch lock is 3-5/8 inches from inside to inside so as long as your 3 inch receiver is under that 3-5/8 at the outer edges you will be fine. You can alternatively use the Draw-Tite Trailer Hitch Lock - 3" Hitch...

    3 inch hitches like what the B&W Tow & Stow 2-Ball Mount # BWTS30040B was designed for use the same hitch pin diameter as the smaller 2 inch and 2.5 inch hitch size which is 5/8 inch diameter.

  • 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 the Weigh Safe 3 180 2-Ball Mounts Be Stowed
    I do have an option for you but the Weigh Safe 3" 180 2-Ball Mounts are not stowable, only the 2" and 2.5" models are. If you want stowable then you'll have to go with the B&W Tow & Stow 2-Ball Mount part # BWTS30040B. The other main difference is that the Weigh Safe is made of aluminum and the B&W is made of steel which is stronger.

  • Adjustable Ball Mount for 3 Inch Hitch on 2018 Ram 2500
    We do have adjustable ball mounts that fit the 3" hitch on your 2018 Ram 2500 but there is not an option for an adjustable ball mount from Curt at this time; instead I strongly recommend checking out the B&W Tow & Stow 2-Ball Mount # BWTS30040B. The Tow & Stow will fit your 3" hitch and will give you a maximum drop of 7-1/2" and maximum rise of 7". It comes with a 2" hitch ball that has a maximum capacity of 7,500 lbs and a 2-5/16" hitch ball with a maximum capacity of 21,000 lbs. The...
