Weigh Safe is the towing industry's leader for Towing Peace of Mind. The Weigh Safe Drop Hitch, constructed of solid billet aluminum and stainless steel, is the only adjustable Ball Mount available with a built-in scale which provides an instantaneous readout of your vehicular tongue weight. This measurement allows you to adjust your load before you hit the road, resulting in a much safer towing experience. With weight ratings ranging from 10,000 lbs to 21,000 lbs our ball mounts are designed to exceed the needs of our customers. Our adjustable ball mount with built in scale is simple to operate and automatically provides a tongue weight measurement every time you couple your trailer, eliminating the need for separate and often difficult to operate commercial scales. When placed in your vehicle's receiver and attached to your trailer, the weight of your trailer's coupler will push down on the tow ball, which in turn pushes down on an internal hydraulic piston that rests on a bed of industrial hydraulic oil. When the piston applies pressure to the industrial hydraulic oil, the pressure reading is displayed on the high strength stainless steel gauge. This measurement will allow you to adjust your load to achieve the 10-15% GTW (Gross Trailer Weight) that is required to be placed on your ball mount while towing. This will help eliminate both Trailer Sway, the leading cause of towing related fatalities in the USA, and jack knifing which greatly reduces the ability of your vehicle to react while on the road. This ball mount includes both a 2” & 2-5/16” tow ball allowing it to be utilized with a wide variety of trailers and applications. The adjustable height allows you the flexibility to tow a variety of trailers with a variety of vehicles. With the built-in flexibility this will be the last ball mount you will ever own. This adjustable ball mount also may be used in the rise position up to the ball mount's maximum height. Not towing? No problem! Just pull off the slider
