Compatible with Lexus GX460 applications, this sensor helps restore accurate height feedback when the original unit is worn or damaged by debris, water, or salt intrusion. Part number RH-5252 is also referenced as 8940860030 for the same application.

Key Features

• New sensor assembly for ride height measurement and suspension leveling
• Black connector with triangle shape for a defined electrical interface
• Blade terminal design with male connector and terminal ends
• Standard-grade construction for replacement service

Detailed Description

Arnott RH-5252 is an aftermarket ride height sensor used to measure the distance between the chassis and the road surface so the ECU can command the air suspension compressor as needed. On Lexus GX460 models, accurate sensor input is important for maintaining proper suspension response and correcting height-related faults caused by a worn sensor. The RH-5252 part number and 8940860030 cross-reference identify the same application.

Common Issues It May Solve

• Incorrect ride height readings from a worn sensor
• Suspension leveling errors caused by damaged electrical feedback
• Faults related to water, salt, or road debris intrusion
• Height control problems after sensor wear or impact damage

Installation Notes

Verify connector shape, terminal style, and mounting location before installation. Mounting hardware is not included. Confirm fitment for 2010-2023 Lexus GX460, rear left, and replace the sensor when height feedback becomes inconsistent.

Quality Assurance

This Arnott sensor is new and built for replacement use in air suspension height control systems.
