    Built-in Tongue Weight Scale

    The Weigh Safe Aero Hitch is the one and only trailer hitch with a built-in scale that 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.

    What is tongue weight and why is it important?

    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.


    Constructed of High Grade Steel, the AERO Hitch is rated for 12,500lbs Gross Trailer Weight and 1,500lbs Tongue Weight.


    The AERO Hitch comes standard with a 2″ Tow Ball and includes our Clamshell Converter for an easy conversion to 2-5/16″


    With the new Slider Lock, adjusting the height of the AERO Hitch is a breeze.


    The AERO Hitch has a unique, sleek design that allows it to be AERO-dynamic and easier to handle.


    • Keep your trailer hitch clean and wash regularly with soap & water.
    • Make sure dust lock covers are always secured on all locks. For replacement dust covers, click here.

    Measuring Tongue Weight:

    • You must have your truck and trailer on flat, level ground in order for your tongue weight gauge to read accurately. Being on a slant or grade changes will compromise the gauge accuracy.
    • After loading the trailer coupler onto the tow ball, move the trailer frame back and forth with your foot to reduce friction. The tow ball and trailer coupler must be jounced to reduce friction and get an accurate tongue weight reading.
    • The Weigh Safe Gauge accuracy is +/- 1.25% over the full range of the scale, which is +/- 50 LBS accuracy.

    Hitch Height Setting:

    • For the best towing performance, adjust the height of your hitch to make the towed trailer level to the ground. To accomplish this, use a level (if on level ground) or measure the distance to the ground on the front and rear of the trailer frame and adjust the coupler height in order to make both measurements the same.
    • For tandem “independent” trailer axles, the height of your hitch does affect your tongue weight. If your trailer coupler is too high, the tongue weight increases and your back axle tires will receive more weight. If your trailer coupler is too low, your tongue weight will read less and increase the weight on the front axle tires. Without being level, your tongue weight will not read true and your tires will wear faster and unevenly.
