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.

Review from a similar Aluminum Tongue Weight Scale in Trailer Hitch Ball Mount


First off I paid for the overnight shipping and it was true overnight shipping. Within 24 hours of ordering it was delivered. Since there are not many 3" hitches on the market yet, I was scepticle about the Qaulity of those that were. I had never bought or heard of weigh safe products before so I was not expecting much. Yet when I saw the qaulity of the hitch as I removed it from the box in the future I will not be hesitant to buy weigh safe products. From the easy key set up to move the height adjustment to the ease of changing the size of the ball with a pull of a pin and with it being made out of aluminum so no rusting or repainting what more could you ask for. Thank you again e-trailer for the fast shipping!!!!! A+A+A+ 346443

Review from a similar Aluminum Tongue Weight Scale in Trailer Hitch Ball Mount


I purchased a Weigh-Safe for my stacker trailer, and found that it was an excellent tool for helping me learn the ideal way to load my trailer to reach the ideal tongue load. I eventually figured out that my 15,000# trailer needed a load distribution hitch, but I still find that the Weigh-Safe is valuable. I will use it when I have a different load, adjust for tongue weight, and then use the load distribution hitch. Quality is excellent, glad I bought it. 757574

Review from a similar Aluminum Tongue Weight Scale in Trailer Hitch Ball Mount


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

Product came right on time. Looks to be very high quality. It’s as beautiful as a trailer hitch can be. I will write a follow up review in one month after I’ve towed with it some. I tow a 7,500 lb trailer around town every day. 525428

Review from a similar Aluminum Tongue Weight Scale in Trailer Hitch Ball Mount


This works great. This is when I first got it. I am only polling my trailer with one pallet of concrete. The total weight of the trailer plus load was 4,600 lbs. It was easy to see and set my tung weight. I would recommend this to anyone who wants to know there tung weight, but you don't want the hassle of using scales. 400547

Ask the Experts about this Weigh Safe Trailer Hitch Ball Mount

  • What Towing Components Need to Be Replaced When Involved in an Accident?
    Because there is really no way to test the hitch, it is recommended to replace the hitch, the ball mount, and any other components involved in an accident. No company will want to take the liability of no visible damage, so I recommend replacing all of the components including the hitch, ball mount, hitch ball, and even hitch pins. I also recommend testing your wiring for proper function using a circuit tester like # PTW2993.

  • How Do You Know If You Need Sway Control on a Trailer
    Unfortunately, there really isn't any way to predict whether or not you are going to experience trailer sway. This is all going to depend on how the trailer is loaded and it's position in relation to the tow vehicle. It really doesn't have much to do with the tow vehicle at all. I might also add that a weight distribution system is not required so you can always use the Weigh Safe 2-Ball Mount part # WS10-3 though it does not have an anti-sway control features.

  • Weigh Safe Adjustable Ball Mount Recommendation for 3 inch Hitch with 1-7/8 inch Hitch Ball
    I have a way for you to accomplish what you are after, but it's not with the part # LTB10-3 that you mentioned as the balls on either side of the platform are a solid piece and they don't offer a 2-5/16 inch and 1-7/8 inch combo. Instead you'd want the Weigh Safe Ball Mount part # WS10-3 which has balls that can be swapped out easily. You'd then need the part # WSB-L and you'd have a 1-7/8 inch ball that you could swap in. This is the same 10 inch drop adjustable ball mount for a 3 inch...
