Weigh Safe Drop Hitch (Tongue Weight)


Free Shipping | Manufactured by Weigh Safe | Ships Lindon, UT

Prime USA Scales offers our Weigh Safe Drop Hitch scale for trailer tongue weight. The built-in scale allows a user a visual weight to adjust your load before you hit the road. This provides safer loading and easy towing experience. In the past gauging your trailer tongue weight was guessing work or you had to rely on a bathroom scale. Now our Weigh Safe’s built-in scale allows any user a quick tongue weight when coupling to a trailer to your ball mount. The weight of your trailer will engage the hitch ball, which will adjust the 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.

Measuring Tongue Weight:

  • You must have your truck and trailer on flat, level ground
  • Being on a slant or grade changes will compromise the gauge accuracy
  • After trailer is coupled 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
  • 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 β€œindependent” 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.

Why is tongue weight 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.
