Product Details

Arnott’s NEW product line focuses on direct-fit air suspension replacements built for proper ride height control and stable handling. AS-2980 is assembled in the USA and uses a pre-built design to simplify replacement of the rear right air strut on the BMW 7-Series. The unit is engineered around the original suspension layout and uses quality materials throughout, including an aluminum top mount, aluminum lower perch, and a durable ContiTech bladder for consistent air spring performance. This part cross-references BMW 37106767864 and 37106778800 for the same application.

• Rear corner sagging or loss of ride height
• Air spring bladder wear or leakage
• Excessive bouncing from a worn shock section
• Uneven rear stance on the BMW 745i or 745Li
• Ride instability caused by a failing rear air strut
