Arnott RH-3859 Rear Ride Height Sensor for Land Rover

The Arnott RH-3859 is a precision-engineered rear ride height sensor designed specifically for 2013-2017 Range Rover, 2014-2017 Range Rover Sport, and 2017-2018 Land Rover Discovery models. This OE-quality sensor plays a critical role in maintaining your vehicle's air suspension system performance by continuously monitoring the distance between the chassis and road surface.

Key Features:

• Accurate height detection monitors exact chassis-to-road distance for real-time ECU adjustments
• Includes linkage arm (adjustable or non-adjustable) and sensor assembly
• Plug-and-play installation designed for seamless integration without complex modifications
• Durable construction built to withstand road debris, water, salt, and harsh environmental conditions
• OEM-level functionality that matches or exceeds original equipment specifications
• Manufactured by Arnott Industries with ISO 9001:2015 and TUV Rheinland certification

The sensor communicates critical data to the Electronic Control Unit (ECU), which signals the air suspension compressor to adjust air pressure in the struts appropriately. This maintains proper ride height, protects suspension components, and ensures a smooth, balanced driving experience. Ride height sensors are vulnerable to damage and wear from road debris, accidents, and salt intrusion, making timely replacement essential for optimal air suspension performance.
