Right Weigh 250-2AXL-FF Onboard Load Scale Kit for Tandem Axle Air Suspensions

The Right Weigh 250-2AXL-FF Analog Load Scale Kit is a dependable, electronics-free solution for monitoring tandem axle weight on trucks and trailers equipped with air suspension systems using a single height control valve (HCV). This flange-mount analog gauge provides accurate, on-the-ground axle weight readings in actual pounds (up to 54,000 lbs), helping drivers verify legal loads before hitting the road.

Designed for durability in demanding road conditions, the 250-2AXL-FF features a 2.5-inch liquid-filled gauge housed in a stainless steel casing. The silicone-filled design resists shock and vibration while maintaining accuracy across a wide temperature range from -40°F to 140°F. Calibration is simple and performed directly on the gauge face, making this system ideal for owner-operators and fleets that prefer a rugged, low-maintenance analog solution.

This model is typically sold as the gauge only. Air lines, fittings, and installation hardware are sold separately in compatible installation kits.
