Detailed Description

RH-3781 is part of Arnott’s NEW product line, which focuses on new, vehicle-specific replacement components rather than remanufactured units. This Arnott RH-3781 ride height sensor is engineered for the front right suspension position on the Acura MDX (YD2) and Acura ZDX (YB1), helping the vehicle computer monitor suspension position and maintain the correct body or headlight height. Ride height sensors are exposed to road debris, water, salt, and impact damage, so replacing a worn sensor can restore accurate height feedback in the suspension system. Fits 2007-2013 Acura MDX, front right. Fits 2010-2013 Acura ZDX, front right.

What It Helps Solve

• Incorrect suspension height readings from a worn front right sensor
• Headlight leveling issues on vehicles equipped with height-based control
• Warning lights related to suspension position feedback
• Height control problems caused by corrosion, water intrusion, or road debris damage
• Signal loss from a damaged linkage arm or sensor housing

Installation Notes and Tips

Verify connector style, terminal count, and front right placement before installation. Inspect the linkage arm, mounting points, and surrounding suspension components for wear or damage before transferring the new sensor into service. After installation, confirm that the vehicle computer reads the correct ride height and that the suspension system responds normally.

Quality Assurance

Arnott supplies new, vehicle-specific suspension components for direct replacement applications. RH-3781 is built as a new OES-style part for Acura MDX and Acura ZDX fitments, with application-specific connector and terminal design for proper integration.
