Arnott RH-5263 Suspension Ride Height Sensor - Front Left
Arnott RH-5263 Ride Height Sensor
Arnott RH-5263 is a new suspension ride height sensor for vehicles with air suspension leveling systems. It measures chassis-to-road distance and sends that signal to the ECU so the system can adjust air pressure in the air struts as needed. This replacement is a direct fit for select Buick Lucerne and Cadillac DTS front left applications.
Key Features
- New standard-grade suspension ride height sensor
- Black oval connector with 1 connector and 1 terminal
- Male connector and male terminal design
- Front left position for select air suspension applications
- Direct replacement for OE part number 25767360
- Arnott RH-5263 for Buick Lucerne and Cadillac DTS fitments
Product Details
The Arnott RH-5263 ride height sensor helps the vehicle maintain proper suspension trim by reporting ride height changes to the control module. When the ECU receives that input, it can command the compressor to add or release air from the struts to keep the vehicle level. This sensor is a practical replacement when the original unit has worn out or been damaged by road debris, water, salt, or impact. This part cross-references OE number 25767360 for the same application.
Common Issues It Can Help Address
- Suspension sitting too high or too low at the front left corner
- Air suspension compressor cycling too often
- Uneven vehicle stance after sensor wear or damage
- Faulty ride height readings sent to the ECU
- Leveling system response problems on Buick Lucerne and Cadillac DTS models
Installation Notes and Tips
Fits 2006-2011 Buick Lucerne, Front Left. Fits 2006-2011 Cadillac DTS, Front Left. Confirm connector shape, terminal style, and mounting location before installation. Inspect the linkage and surrounding suspension components for corrosion, impact damage, or binding that could affect sensor readings. After installation, verify ride height operation and clear any stored suspension fault codes if required.
