Arnott RH-5251 Rear Right Ride Height Sensor
Arnott RH-5251 is a new suspension ride height sensor for the rear right position on select Lexus GX460 models. It measures chassis-to-road distance and sends that input to the vehicle’s ECU so the air suspension system can adjust ride height as needed.
For Lexus GX460 owners dealing with air suspension warning lights or uneven stance, this sensor provides a direct replacement option for the rear right corner. The RH-5251 is built as a standard-grade, OE-style sensor with a black connector and male blade terminals.
Key Features
- Fits 2010-2023 Lexus GX460, rear right
- New suspension ride height sensor for air suspension systems
- Black connector with triangle shape
- Male connector and male blade terminal design
- Standard-grade replacement for the rear right sensor location
- Cross-reference: Toyota 8940760040
- Arnott RH-5251 is a direct-fit service part for the Lexus GX460 rear suspension
How It Works
The ride height sensor monitors the distance between the chassis and the road surface, then relays that information to the ECU. The ECU uses the signal to command the air suspension compressor and air struts to raise or lower the vehicle, helping maintain proper ride height on the Lexus GX460. Arnott RH-5251 is a practical replacement when the original rear right sensor is worn or damaged.
Common Issues This Part Can Address
- Uneven vehicle stance at the rear right corner
- Air suspension warning messages related to ride height input
- Incorrect compressor cycling caused by faulty sensor readings
- Suspension height that does not respond properly to load changes
- Sensor failure from road debris, water, salt, or impact damage
Installation Notes
Verify rear right fitment before installation on 2010-2023 Lexus GX460 models. Inspect the connector, terminal style, and mounting points against the original sensor before replacement. Because ride height sensors affect air suspension control, confirm proper calibration and system operation after installation.
Quality Assurance
Arnott supplies new aftermarket suspension components built for OE-style service replacement. RH-5251 is made for the rear right position and follows the original sensor layout used on the Lexus GX460 air suspension system.
