Right Weigh 250-2AXL-FF Analog Load Scale Gauge
The Right Weigh 250-2AXL-FF Analog Load Scale 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 displays axle group weight directly in pounds with a measuring range up to 54,000 lbs, helping drivers check load distribution and verify axle weight before getting on the road.
Designed for demanding trucking environments, the 250 Series features a durable 2.5-inch liquid-filled gauge with stainless steel construction. The silicone-filled design helps protect against shock, vibration, and harsh operating conditions.
With no batteries, Bluetooth, or electronics required, this mechanical scale provides a simple and reliable weight monitoring solution for owner-operators and fleets.

Truck & Trailer Fitment Compatibility
The Right Weigh 250-2AXL-FF is designed for commercial trucks and trailers with air ride suspension systems using one height control valve (HCV).
The gauge connects to the suspension air system and uses air pressure changes to estimate axle group weight after calibration.
Compatible Applications:
- ✓ Semi tractors
- ✓ Day cab trucks
- ✓ Sleeper trucks
- ✓ Straight trucks with air suspension
- ✓ Flatbed trailers
- ✓ Step deck trailers
- ✓ Dry van trailers
- ✓ Reefer trailers
- ✓ Other commercial air ride equipment
Required Setup:
- Suspension Type: Air ride suspension
- Axle Configuration: Tandem axle group
- Height Control Valve: Single HCV applications
Important: This scale is designed for air suspension systems only. It does not work with mechanical spring suspension because axle weight is calculated using air pressure changes.

Recommended Installation Kit
The Right Weigh 101-SK Air Line Installation Kit – 30 ft. Hose & Fittings for Load Scales is recommended for a complete and professional installation.
The 101-SK kit includes the required air line, fittings, and installation components needed to connect the 250-2AXL-FF gauge to the vehicle's air suspension system.
Note: The 250-2AXL-FF is typically supplied as the gauge only. Air lines, fittings, and installation hardware are available separately with the compatible 101-SK installation kit.
How It Works
- Connects to air suspension: Reads air pressure from the air bag system
- Converts pressure into weight: Suspension pressure changes are displayed as axle weight
- Calibrate once: Adjust the gauge using a known axle weight
- Instant readings: Displays tandem axle weight directly on the gauge
