Weigh Safe WSUN-1
Universal Tow Ball w/ Built In Scale
For 2″ & 2-5/16″ Trailer Coupler Sizes
See Video Below

This Weigh Safe hitch ball 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 peace of mind, knowing that your setup is safe. And towing trailers with different coupler sizes is a breeze thanks to the magnetic, clamp-on 2-5/16” ball adapter. Stainless steel construction resists rust and corrosion.

Ensures Proper Towing and Improves Performance

Pressure on the ball sends a reading to the built-in scale that measures tongue weight (lbs.)

GMC guidelines for proper towing states tongue weight should be no less than 10 percent of gross trailer weight (GTW) and no more than 15 percent. For example, tongue weight for a 10,000 pound trailer should be no less than 1000lbs. and no more than 1500lbs.
(Note: Weigh Safe max tongue weight is 1500lbs. Do not initiate tow if your reading is in the red zone).

How Tongue Weight Affects Your VehicleWeigh Safe Hitch for Safer Towing

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.

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.
