Product Description

Weigh Safe trailer hitches are the only hitches on the planet with a built-in scale to measure tongue weight to improve towing performance. Not enough tongue weight or force on the hitch/tow ball causes an increase in trailer sway from side to side, making it difficult to control. Conversely, too much tongue weight or force on the hitch/tow ball could overload the rear tires of the towing vehicle, pushing the rear end of the vehicle around. The Weigh Safe Drop Hitch effectively measures the tongue weight of your towing load, improving the vehicle tow load balance and performance.

Pressure on the ball sends a reading to the built-in scale that measures tongue weight (lbs.) As an example, GMC guidelines for proper towing state 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)



The tongue weight is the static force the trailer tongue exerts on the hitch/tow ball. Proper trailer tongue weight improves the vehicle and trailer towing experience by improving performance. Not enough tongue weight or force on the hitch/tow ball causes an increase in trailer sway from side to side, making it difficult to control. Conversely, too much tongue weight or force on the hitch/tow ball could overload the rear tires of the towing vehicle, pushing the rear end of the vehicle around. This could also negatively affect the vehicle handling. Performance is impaired as you might not be able to go around corners and curves properly, and your vehicle may not stop quickly enough when you press the brake pedal. The Weigh Safe Drop Hitch effectively measures the tongue weight of your towing load, improving the vehicle tow load balance and performance.
