Detailed Product Features and Specifications

The Arnott New AS-3404 air suspension strut is designed to replace factory air struts on compatible BMW models, providing reliable air ride suspension functionality. It features a hydraulic internal damper type that ensures smooth shock absorption without adjustable damping. The strut is air adjustable, allowing the vehicle's suspension system to maintain optimal ride height and comfort. The progressive spring rate and spring-assisted shock design contribute to improved handling and load support.

This strut includes a black protective boot and bearing plate to safeguard internal components. The lower mount uses a base cup design, while the upper mount is a stud type with an included isolator to reduce noise and vibration. Heavy duty crimping rings for the bladder enhance durability under pressure. Gas charging further supports consistent performance under various driving conditions.
