ACDelco 84365776 Rear Suspension Auto Leveling Position Sensor

The ACDelco 84365776 is a genuine GM rear suspension automatic leveling position sensor designed to monitor vehicle height and maintain proper ride level. This sensor is a critical component of automatic leveling systems, detecting changes in suspension position and sending signals to the vehicle's control module to adjust headlight aim and maintain optimal beam patterns as load conditions change.

Key Features:

• Genuine ACDelco OE quality replacement sensor
• Monitors rear suspension position for automatic leveling systems
• Integrates with automatic forward lighting leveling systems
• Direct-fit rear driver side application
• Ensures proper headlight aim under varying load conditions
• Precision-engineered for reliable performance and durability

This sensor is essential for vehicles equipped with automatic headlight leveling systems, which adjust headlight beam angle based on vehicle load and suspension position. When the rear suspension compresses or extends due to cargo weight or passenger load, this sensor detects the change and signals the system to adjust headlight aim accordingly, preventing glare to oncoming traffic and maintaining optimal road illumination.
