Keep your Lexus reporting accurate ride height with the AISIN Suspension Ride Height Sensor (HST025), a rear-right assembly that drops in as a direct replacement on the 2004-2006 Lexus RX330, 2007-2009 Lexus RX350, and 2006-2008 Lexus RX400H (All engines). Mounted at the rear right of the suspension, it monitors the position of the suspension relative to the chassis and feeds that data to the vehicle's computer.
- OE-engineered assembly: designed as a direct replacement and includes the mechanical linkage arm.
- Complete unit: the assembly includes the sensor and linkage arm (adjustable or non-adjustable).
- Continuous signal: sends continuous electric signals to the computer.
- System input: helps maintain correct headlight alignment and/or suspension height.
If a failed ride height sensor is the cause of erratic headlight leveling or incorrect suspension height readings, replacing this rear-right unit restores that input to the system. Signs it may need replacing include self-leveling faults, warning lights, or headlight aim that no longer adjusts. Diagnose the cause before replacing. Made in Japan.
