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.

Until you see this hitch in person, it's hard to appreciate the high quality look and feel. It looks like it was made for an airplane, forged aluminum, well engineered. I used mine just a few days ago to tow my new tilt trailer home. The scale only showed about 100# or so but the trailer was empty. It was easy to adjust for the correct height and that feature will be handy when we get a different horse trailer. I also bought the locking hitch pin. Wish I had know to get them keyed alike but not a big deal. Tim was a big help in selecting this hitch and locking pin.

Used the hitch to haul some square bales of hay during the summer. The scale showed about 500 hitch weight which was approx 10 of the entire load. That was ideal, towed great! Im glad I bought it. Very satisfied.

When I switched tow vehicles from a Silverado to a Durango SRT I had to be a lot more conscious of tongue weight. The adjustability in this hitch and the tongue weight scale let me set up each trailer to tow flawlessly behind the Durango SRT.

- WS4-2

Mostly the mount is used for personal use with a 20' trailer. This is the most amazing ball mount not only for the ability to adjust the height but also being able to keep the tongue weight down. Probably one of my biggest concerns on trailering a vehicle is how much load is on the ball mount/hitch.

It works great! Having the hitch adjustable for multiple trailers is awesome. Also, the scale work perfect for the times I haul the car trailer. No longer do I have to worry about excessive tongue weight or the trailer whipping back and forth for too much weight on the back.

This is a nice looking hitch, wasn't really after the weigh feature just the design of the hitch. Other hitches always have another ball upside down at all times and I didn't want that, the balls and height are easy to change out. The only thing I don't like is it only comes with 2 balls and I had to order a third to cover all sizes, it should have come with all three!

- WS4-2

Love this hitch. Watching the video on the etrailer site is what sold me on the product and it’s exactly the way it was presented. We have 2 trucks of different heights and 3 trailers that use 2” and 2 5/16” balls. Changing out the different hitch balls takes about 30 seconds... No vise needed, no huge wrenches to torque the nut down. I also purchased the available locking receiver pin, keyed the same as the adjustable hitch pin lock.. I also am very happy to know exactly what my trailer tongue weight is. Easy to use, lightweight, multipurpose, and looks pretty cool, too.

- WS4-2

Works great with my 22 ft bass boat and trailer. I can level the trailer for better towing. Also with the scale I can load my equipment trailers to keep the tongue waite to spec.

- WS4-2

An absolute must-have for safe towing, one of the best accessories I've purchased. Although, It would be great if it had an option for a lower resolution scale for lower towing capacity vehicles. (For example 0-1000 instead of 0-2200).

- WS4-2

Use it on a 6 cylinder Tacoma with fairly low tongue rating to pull a 5x8 single axle dump trailer. Great design, easy to use. Takes the guess work out of balancing your load. You have to give the scale a few seconds before reading because it is hydraulic. Not cheap but certainly worth the money.

Probably use it once or twice a month with no issue.

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.

- WS4-2

Looks great, definitely adds a touch of class to what is ordinarily an unsightly part of the vehicle. I'm suspicious about the accuracy of the scale, as the entire range is large and any particular vehicle or trailer is only going to use a small faction of the whole scale, and the indicator doesn't move very much within that range.

- WS4-2

This is a great setup and takes all the guess work out of receiver weight. I load my car trailer so much faster now due to not having to guess how far up or back to keep receiver weight correct. The quality of this system is by far the best I’ve seen. Works great and it’s bullet proof as well. Buy it and you won’t be sorry!

I love this weigh safe system. Get one. Just, get one.

This product does not disappoint. I just received it today. Fit and finish are superior even to my strict standards. One thing that is different about the unit compared to the published pictures is that the tang that inserts into the receiver is squared off as opposed to angular as shown in the pictures. I prefer this squared look/style much more. I am very anxious/excited to use this hitch. Only time will tell how the scale function will last. Based on the quality machining and fitment, I am betting it will last a long time. AMERICAN MADE!!!!

- WS4-2

Slick, and it doesn't leave you guessing what the tongue weight is on any item loaded onto the trailer. Very well built. BTW, George and the folks at Etrailer are superb. I placed an order at night on a weekend, and George was already looking at the order to see if one of the items ordered could be substituted with another product if I didn't want to wait on the original part. These folks ship about as fast as anybody on the web, and I have never received a bad unit/part or anything else.

- WS4-2

Best receiver and ball assembly on the market! The built-in scale told me immediately that my trailer's tongue weight was fine and not overloaded as I had previously thought. Masterfully built and exacting as if it were for the aircraft industry. Forget what it costs and buy it. You won't be disappointed.

- WS4-2

The hitch worked very well most of the year, then the scale gauge quit working. I always pull the same trailer so my weight was set. Disappointed in the scale.

- WS4-2

Timely delivery, NICE HITCH! I just wish it came with an 17/8" ball as well.

- WS4-2

I researched the internet for a versatile (yet reasonably-priced) hitch for my Sierra HD. All searches led back to this Weigh Safe hitch on etrailer.com. The hitch is premium quality with excellent machined surfaces, and the built in scale really helps to balance the load for the safest possible tow. I love the fact that I can invert the ball and attach it on the back side of the hitch to eliminate those "shin-busters" when not in use. I also splurged on the locking hitch pin set to ensure that no one else can borrow my hitch, and I love that both locks are keyed the same to eliminate one extra key on my keychain. I highly recommend the set to anyone who wants a top quality hitch, and I fully recommend that they purchase from etrailer.com!

Update: It has been one year since purchasing, and I am still completely satisfied with this product. As expected, the aluminum construction has weathered well. I keep the hitch inverted facing the front of the truck when not in use, so there are times when I need to squirt a bit of WD40 into the lock to clean out the debris, but I have had no issues with any of the materials andor components. The dust cover on the locking pin definitely keeps the lock free of debris. I highly recommend both products and etrailer.com. You cannot go wrong with either.

This is a very good product I have no complaints. My daughter ‘s RV Tongue weight is close to 1000 pounds and we thought it was about 600 at the most. It is also well terminated and looks cool on my truck. Attached a pictute

Works well, was able to balance a trailer load using the built in scale and so far it has performed well. The scale takes a while to respond so you can't test it by standing on it.

Lite weight and strong. Awesome looking too. This is my second time buying one of these for my vehicles. Cant live without it !

Very nice ball mount. Well built. Looks good on my truck.

After a year of use it still looks as good as new. The scale is as accurate as the day I purchased it.

But I was treated very well and was helped immediately with my problem!! Will check in after I use the product for a while!! Great customer service

Works great, I don’t use it but several times a year. That being said it works as advertised!!

  • Does the Weigh Safe 2-Ball Mount Come with a Hitch Pin
    The Weigh Safe 2-Ball Mount part # WS4-2 does not come with a hitch pin which is the case for most of our adjustable ball mounts. That said, a perfect option for you is to use the Locking Dual Pin Assembly and Hitch Pin Set part # WS06 which comes with matching hitch pin and adjustment pin locks so you can use one key for both locks. If you don't care about matching locks then you can just use the Weigh Safe Hitch Receiver Lock part # WS05.

    The Weigh Safe 2-Ball Mount # WS4-2 has a standard 2-inch shank, in this case made of milled billet aluminum for strength. It is not sized differently due to its material. I went to our warehouse and measured the shank with a precision digital caliper and found it to be 1.943-inches.

    The hitch balls included in the Weigh Safe 2-Ball Mount with Built-in Scale # WS4-2 will need to be greased. These are stainless steel hitch balls and so they are corrosion resistant. I recommend a hitch ball grease like White Grease Hitch Ball Lub # 58117 for use with the Weigh Safe ball mount hitch balls. This grease helps reduce friction between the hitch ball and coupler while towing. The # 58117 grease is water resistant and non-toxic.

Almost all 3500 lb and up axles can handle 15 inch tires which is most likely what you have, but there are still a few things to consider and check before making this change.
