Detailed Description
Arnott RH-3998 is an aftermarket ride height sensor used to monitor the distance between the chassis and the road surface. That input is sent to the ECU, which then commands the air suspension compressor to raise or lower the air struts to maintain proper vehicle level. This makes RH-3998 a relevant replacement for Tesla S front sensor applications where accurate height feedback is required for suspension control.
This part cross-references Monroe Shocks & Struts (e.g., 600651400B) for the same application. It is listed for 2012-2015 Tesla S, front, and 2016 Tesla S, front with a 4-pin connector note. The part number RH-3998 is also useful when verifying the correct Tesla S front ride height sensor before ordering.
What It Helps Address
- Incorrect suspension height readings
- Uneven vehicle stance at the front end
- Air suspension compressor cycling caused by faulty sensor input
- Warning lights related to ride height or leveling feedback
- Sensor damage from road debris, water, salt, or impact
Installation Notes
Confirm the connector style, terminal count, and front position before installation. This Tesla S sensor uses a female oval connector with 4 terminals, so matching the electrical interface is important for proper operation. Inspect the surrounding suspension linkage and wiring for corrosion or physical damage before installing RH-3998.
Quality Assurance
Arnott supplies new aftermarket suspension components built for vehicle-specific fitment and system function. RH-3998 is a new part intended for front ride height sensor replacement on the listed Tesla S applications.
