Product Details

Arnott’s New product line focuses on replacement air suspension components built as complete assemblies rather than remanufactured units. AS-3406 follows that approach for the rear right corner of the BMW 7-Series, combining an air-adjustable strut with a hydraulic internal damper and progressive spring rate to restore proper suspension behavior. The assembly is built with long-lasting sealing components and protective hardware to help maintain air retention and damping performance in daily driving.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Rear suspension sag on a BMW 7-Series
• Air leaks from a worn OE air strut
• Excessive bouncing or reduced damping control
• Uneven ride height at the rear right corner
• Noise or wear from deteriorated strut seals and isolators
