Product Details

Arnott AS-3375 is part of Arnott’s Remanufactured line, which focuses on rebuilding original-style suspension components rather than replacing them with generic assemblies. Each strut is steam cleaned, media blasted to bare metal, and rebuilt with critical wear items replaced before final testing. The internal hydraulic damper is recharged, and the assembly is finished with a corrosion-resistant coating for long-term service in the rear suspension.

This part cross-references BMW 37106874593 and 37107915953 for the same application. It is a direct-fit rear left air suspension strut for BMW 7-Series models including 740i, 740i xDrive, 745e, 745e xDrive, 745Le xDrive, 750i xDrive, 750Li xDrive, 740e xDrive, 750i, 750Li, and 740Le xDrive where listed.
