Weigh Safe ball mount coupled to a trailer

This Weigh Safe ball mount has an easy-to-use, built-in scale that measures your trailer's tongue weight every time you tow. If the scale indicates that your tongue weight is too low or too high, you can adjust it before you head out so that you can complete your journey with the peace of mind that your setup is safe.


What is Tongue Weight?

Tongue weight (TW) refers to the weight that the fully loaded trailer exerts downward on the hitch ball of the tow vehicle. Tongue weight is typically 10 percent - and should not exceed 15 percent - of your gross trailer weight. For example, a 10,000-lb trailer should have a tongue weight between 1,000 lbs and 1,500 lbs. You can adjust the tongue weight of your trailer by removing or adding cargo, or redistributing the load on the trailer. The tongue weight should not exceed the capacity of your tow vehicle, your hitch, or any of your towing components.


Why is Tongue Weight So Important?

Weigh Safe helps ensure proper trailer tongue weight

Simply put, too little tongue weight can cause trailer sway and too much tongue weight can cause the tow vehicle to perform poorly. You may have difficulty steering, gaining traction, or braking when driving a setup that has too much weight pushing down on the rear of the vehicle. Ultimately, towing with an improper tongue weight can cause you to lose control of your vehicle or cause your trailer to separate from the vehicle.


Built-In Tongue Weight Scale


The gauge of the Weigh Safe built-in tongue weight scale

The Weigh Safe ball mount's built-in scale signals you to adjust your load before you hit the road, resulting in a much safer and enjoyable towing experience. Before this ball mount, gauging your trailer's tongue weight was a hassle. You had to rely on inefficient bathroom scales, make a trip to the weigh station, or purchase a separate tongue weight scale. But with the Weigh Safe's built-in scale, measuring your tongue weight is as easy as coupling your trailer to your ball mount. Simply hook-up your trailer to the Weigh Safe ball mount just as you would any other ball mount. The weight of your trailer will push down on the hitch ball, which in turn pushes down on an internal hydraulic piston that sits on a bed of oil. When the piston drops into the oil, the pressure reading is sent out to the scale.


Easily Adjusts to Fit Your Setup

Weigh Safe ball mount has adjustable height

Adjusting and setting up the Weigh Safe ball mount to work with your specific trailer is easy. First, unlock and pull out the dual pins and remove the platform from the shank. Next, pull out the hitch ball retaining pin from the back of the platform and insert either the 2" or 2-5/16" hitch ball. A 1-7/8" hitch ball (WSB-L - sold separately) is also available. Then reinsert the retaining pin to secure the ball to the platform. Replace the platform and slide it along the shank to the desired height. Insert the dual pins and use one of the included keys to lock the pins in place.


Weigh Safe ball mounts installed in drop and rise positions

The Weigh Safe ball mount can be used in either the drop or rise position to best suit your application.


Superior Aluminum and Stainless Steel Construction

From the first moment that you lay eyes on the Weigh Safe ball mount you'll see that you're getting a superior, well-made product. The Weigh Safe's shank and ball mount platform are made entirely of 6061 T6 billet aluminum, which is the same material that is used to build aircraft components, automobile frames, and freight liners. This type of aluminum is known for having superior strength while maintaining its light weight, which makes it highly desirable over hollow steel components. 6061 T6 aluminum is also rustproof, which means the Weigh Safe hitch will maintain its clean, shiny, and impressive appearance for years to come. And the hitch balls are made of solid stainless steel, offering far greater protection against rust and corrosion than other steel hitch balls that are only painted or plated on the surface.


The Weigh Safe ball mount meets VESC V-5 regulations and is SAE J684 certified. These regulatory bodies - the Vehicle Equipment Safety Commission and the Society for Automotive Engineers - create standards for the design, construction, and performance of automotive and towing accessories. Weigh Safe has had this ball mount thoroughly tested in simulation to ensure that it complies with these standards. The result is a strong, safe, sturdy product that is built to last.

Video Transcript for Weigh Safe Ball Mounts - Adjustable Ball Mount - WS6-3 Review

Today we're going to take a look at the Weigh-Safe Adjustable 2-Ball Mount with the built-in tongue weight scale for a 3" hitch. This has a 6" drop and a 6" rise, and a 21,000-pound gross towing weight capacity. This is an adjustable ball mount with the included hitch balls thatll let you hook up your trailer to your tow vehicle. The shank portion right here is whatll slide into your 3" hitch receiver opening, and then the hitch ball is whatll provide the connection point for your trailer coupler. This is a Weigh-Safe ball mount that has this easy to use built in scale here thatll measure your trailers tongue weight every time you tow. The scale indicates your tongue weights too low or too high.

You can adjust it before you head out so that you can complete your trip, going with the peace of mind that your setup is safe. Now, Weigh-Safe is the only ball mount that has this built-in scale to measure the tongue weight. You might wonder why tongue weights so important. Well, too much tongue weight can affect your driving maneuverability, and too little and your trailer might fishtail, swing into other lanes, or might just come off the ball. Now, tongue weight usually is typically 10 to 15% of your gross trailer weight. For example, a 10,000-pound trailer should have a tongue weight between 1,000 to 1,500 pounds, so you can adjust the tongue weight of your trailer just by removing or adding cargo, or either redistributing the load thats on the trailer.

This Weigh-Safe scale right here is linear rated up to 2,200 pounds. Has marks on the gauge that are in 100-pound increments. Basically, measuring your tongue weight's as easily as just coupling your trailer to this ball mount. Simply hook your trailer up to the ball mount just as you would any other ball mount. The weight of the trailer will push down on this hitch ball. The hitch ball, which in turn pushes down on an internal hydraulic piston thats on the inside of the mount here, that piston sets on a bed of oil, so when the piston drops into the oil the pressure reading is sent out to the scale.

This is an adjustable height, so you can see right here, lets you tow trailers of different heights with the same vehicle. The ball mount platform right here will slide up or down the shank, and secure in place with the included dual locking pins, as opposed to some of your adjustable ball mounts that use the individual pins, and they can be a hassle. It comes with the two keys. All you have to do is put the key in, turn it to unlock it, and you can slide the dual pins out simple as that. Then you can see you can set your adjustment just like that. Then when you get it to the correct height, you can actually take the key out, and it will lock automatically.

When you get it to the correct height you want it at, line the holes up, just push it in all the way, and itll lock into place. You only need the key to remove it. Put the key in, turn it, and remove it just like that. Simple as that. Now, this Weigh-Safe Ball Mount can be used in either the drop position like it is now, or you could flip it over and use it in the rise position. Either one of those positions will gain you 6". If we measured here, its in the rise position, you can see theres your 6" rise, and if we drop it back down into the lowest drop position you can see right at 6" again. Again, its incremental height adjustment. These holes are at 1" center to center. Now, I do want to measure the distance from the center of the hitch pinhole to the center of the hitch ball. I'll lift that up just so we can get a correct measurement. Center to center, the ball is going to be right at 8 3/4" center to center. If you notice, it does come with two different size hitch ball. This will let you tow trailers with different coupler sizes, and switch the balls pretty simple. Let me show you how to do that. Right now, we have the 2" ball in there, and you can see the 2" is stamped at 8,000 pounds. Here we have a comes with a 2 5/16 that has 21,000 pounds. To switch it, all you do is pull this ring that has the retaining pin all the way out. Take the ball right out just like that. Take your 2 5/16. Line the hole up with the hole in the mount. Put your pin all the way in. Push it till it closes, and now youre set up to do 2 5/16 hitch ball. Very simple to do. The balls are stainless steel, so they are corrosion resistant. Now, the hitch shank right up here in the mounting platform, theyre made of a 6061-T6 aluminum. Thats used in a lot of aircraft construction, and offers superior strength and durability. Again, the application on this is with 3" x 3" trailer hitch receivers. The gross towing weight capacity, again, depends on the ball you use. If its the 2", that'd be 8000 pounds. The 2 5/16 will be 21,000 pounds. They are stamped on it. Maximum tongue weight overall its going to take is 2,200 pounds. This part is made in the USA. That should do it for the review on the Weigh-Safe Adjustable 2-Ball Mount with the built in tongue weight scale for a 3" hitch with a 6" drop/6" rise, and a 21,000-pound weight capacity.

I actually didn’t use this for a year, for every time I used it I had to pay postage to send it off because of a faulty gauge, the company eventually recalled the gauge but I haven’t used it since the new gauge was installed.

I bought this hitch which was pretty costly compared to others without the built in scale. I don’t know if the scale ever was accurate. The scale busted after three short tows. Each tow had a tongue wait anywhere from 300-500 lbs. Well within limits of the receiver. It always weighed way higher and after the 3rd trip with a trailer it stuck at full gauge and never moved again.... super disappointed. But I liked the way the hitch looked and kept using it anyways. After about 4 months i needed to change from the 2 5/16 ball to the 2” ball. That’s when I realized how much play had started to occur in the hitch and ball.... tossed it in the scrap pile after that. A hitch needs to be safe and not have wear and tear occur in such a short period of time. 1 star. 641887

Scale stopped working after 9 months. It is covered by warranty but shipping the heavy hitch for repair is on your dime. People at weigh safe advised it was a common problem with hitches made prior to late 2018 due to corrosion problems. Since that time the hitches are being assembled with a stainless scale. It's a good hitch but be careful that you are not buying NOS (new old stock) product. This has nothing to do with etrailer as they have always been a great seller. 634702

I read 2 reviews and I think I saw video, that shows this ball and mounting being reversed to fit under the receiver. It does not do that, so I returned it. My pickup will barely fit inside my garage and I didn't want to have to remove the hitch every time I drive it inside. I feel guilty when I park with that hitch sticking out so someone might walk by and bang their leg on it. Aside from that one drawback it is a very nice hitch. It's hard to buy things sight unseen, and paying Freight back to the shipper makes me question the wisdom. 570058

Review from a similar Weigh Safe Aluminum Tongue Weight Scale in Ball Mounts


This is my second purchase of the Weigh Safe hitch. I had to buy a smaller one because I traded trucks and the 3" shaft was too large for the new truck's receiver. The first one I had was used around 3 years and I was 100% satisfied with it so it was an easy decision for this purchase. 679829

  • Correct Size Weigh Safe Ball Mount for 2019 Ford F-350 Dually
    Based on my research your 2019 Ford F-350 Dually would have come from the factory with a 3 inch trailer hitch receiver. With that being said I highly recommend taking a quick measurement on the receiver opening just to be sure as there are trim levels available for the F-350 that included a 2-1/2 inch receiver as well. If you do indeed have the 3 inch receiver then the Weigh Safe 2-Ball Mount # WS6-3 that you referenced will work perfectly. If you find you have the 2-1/2 inch receiver...

  • Ballmount Drop Needed for Rental Trailer
    The average bumper pull trailer coupler height averages between 16-22 inches. When we measure to determine the rise or drop of ball mount needed, we measure from the inside top of the receiver tube, which would place your receiver height at roughly 24 inches. The rental company should be able to tell you the coupler height of the trailer you're renting, but if they cannot the 8 inch maximum drop provided by the # WS8-3 would allow your trailer ball to be set as low as 16 inches, which...

  • How to Determine How Much Drop is Needed from Ball Mount to Tow Trailer Level
    I have attached a help article on how to determine the rise or drop you need for a ball mount. Basically, you will want to park your truck and trailer on flat ground. First, measure from the ground to the top of the trailer hitch receiver opening. Next, measure from the ground to the bottom of the trailer coupler. If the trailer hitch receiver opening is taller than the bottom of the trailer coupler, then the difference between the two measurements is the amount of drop you will need in...
