Detailed Description
Arnott RH-5249 is an aftermarket ride height sensor used on the rear left side of the Lexus LX570 from 2013 through 2021.

This makes RH-5249 a practical replacement when the original sensor is no longer sending accurate signals. This part cross-references Toyota 8940860040 for the same application.
