Detailed Description

Arnott AS-2978 is engineered as a direct replacement rear right air suspension strut for BMW 745i, 745Li, 750i, 750Li, 760i, and 760Li models listed below. It is designed for vehicles equipped with EDC S223A and restores the air spring and damping function in one pre-assembled unit. Arnott assembles this NEW line product in the USA using a CNC-machined aluminum top mount, aluminum lower perch, and a heavy-duty air bladder for consistent suspension response. This part cross-references BMW 37106778798 and 37126758580 for the same application. Arnott AS-2978 is a practical OE-style replacement for the BMW 7-Series rear suspension where ride height control, damping, and air spring integrity are critical.

Installation Notes and Tips

Verify the rear right position and confirm EDC-equipped fitment before installation. Transfer no mounting hardware unless your vehicle-specific service procedure requires it, and follow the included installation manual for assembly and setup. Inspect the air line connection, upper stud mount, and lower loop/eyelet interface during replacement to ensure a proper seal and correct suspension operation.

Arnott’s NEW product line uses new components rather than remanufactured parts, with materials selected for OE-style fit and consistent suspension performance. The detailed installation manual supports accurate installation on the BMW 7-Series E65 and E66 platform.
