The Safe Load ISR (Industry Standard Rail) Gooseneck Ball is a 2-5/16” tow ball made of high-strength stainless steel with a 3” ball offset from the centerline allowing for easy adjustment for different bed sizes. It has a durable powder coated finish with dual gauges on either side for ease of use.
The Safe Load ISR Gooseneck Ball is the one and only gooseneck 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 gooseneck hitch, gauging your trailer’s tongue weight or pin load 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 gooseneck hitch. Simply hook-up your trailer to the Safe Load ISR Gooseneck Ball just as you would any other gooseneck hitch. The weight of your trailer will push down on the gooseneck 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) or pin load weight refers to the weight that the fully loaded trailer exerts downward on the back axle of the tow vehicle. Tongue weight is typically 15 percent – and should not exceed 25 percent – of your gross trailer weight. For example, a 10,000-lb trailer should have a tongue weight between 1,500 lbs and 2,500 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.
