Detailed Description

Arnott RH-3763 is built as an OES vehicle-specific replacement for the front left position on the Lexus LS460 and LS460L from 2009-2017, plus the Lexus LS600h AWD from 2008-2016. The sensor assembly uses a 3-terminal male pin layout with a black female connector and is supplied new for direct replacement service. By reporting suspension position to the control system, the RH-3763 helps the vehicle maintain proper ride height and related headlight leveling function where equipped. The Arnott RH-3763 is a practical replacement when the original Lexus ride height sensor has worn or been damaged.

What It Helps Address

• Incorrect suspension ride height readings
• Warning lights related to ride height sensor faults
• Uneven vehicle stance at the front left corner
• Headlight leveling issues tied to suspension height input
• Sensor damage from road debris, water, salt, or impact

Installation Notes and Tips

Install at the front left suspension location only. Verify connector style, terminal count, and linkage orientation before installation on the Lexus LS460, LS460L, or LS600h AWD. Because ride height sensors are exposed to the road environment, inspect the mounting points and surrounding suspension components for corrosion or damage before replacing the sensor.

Quality Assurance

Arnott supplies this RH-3763 as a new OE-style replacement built for the listed Lexus applications. It is engineered to match the vehicle-specific sensor function required by the suspension control system.
