Detailed Description
The Arnott RH-3874 ride height sensor monitors suspension position so the ECU can command the compressor and air struts to raise or lower the vehicle as needed. Accurate height sensing is critical for maintaining proper stance, suspension response, and system operation on air-equipped trucks and SUVs. This part number RH-3874 is used on front left applications for 2015-2020 Cadillac Escalade and Escalade ESV, 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon and Yukon XL, and 2015-2018 Chevrolet Silverado 1500 and GMC Sierra/Sierra 1500.
This Arnott ride height sensor is a practical replacement when the original sensor has worn out or been damaged by road debris, impact, water intrusion, or salt exposure. It is a direct-fit suspension sensor for vehicles that rely on electronic ride height control.
What It Helps Address
- Incorrect vehicle ride height readings
- Air suspension compressor cycling caused by faulty sensor input
- Uneven front left suspension leveling
- Warning lights or suspension faults related to height sensing
- Sensor damage from corrosion, debris, or impact
Installation Notes and Tips
Install on the front left position only for the listed applications. Verify connector style, terminal count, and mounting points before installation. Because mounting hardware is not included, reuse or source the required hardware as needed. After installation, clear any suspension fault codes and confirm the vehicle levels correctly through a full height cycle.
Quality Assurance
Arnott supplies aftermarket suspension components engineered for air suspension service, and this RH-3874 sensor is supplied new for replacement use. It cross-references GM 23152098 for the same application.
