Product Details

Arnott AS-3800 is built as a direct replacement air suspension strut for the rear right corner of the BMW 640i xDrive Gran Turismo and related BMW Touring/GT applications. The Arnott New product line focuses on new replacement suspension assemblies rather than remanufactured units, and this strut follows that approach with a complete air spring and damper assembly designed around OE-style fitment and performance. AS-3800 also cross-references BMW OE part numbers 37106872968 and 37106882822 for the same application.

The assembly includes a black protective boot, bearing plate, lower mounting isolator, and internal hydraulic damping with a progressive spring rate. Arnott AS-3800 is intended for drivers replacing a worn rear air strut on a BMW 5-Series Touring or 6-Series GT, including vehicles equipped without VDC electronic shocks.

Common Problems This Part Can Address

• Rear suspension sag or uneven ride height
• Air leaks from a worn strut bladder or seals
• Excessive bouncing, harshness, or reduced damping control
• Noise from deteriorated internal suspension components
• Ride quality loss at the rear right corner

Installation Notes and Tips

Fits 2018-2019 BMW 640i xDrive Gran Turismo, rear right. Confirm the vehicle is equipped for this application and verify OE interchange before installation. Inspect the air line, connector valve, and surrounding suspension components for wear before reassembly. Because this is an air suspension strut, system depressurization and proper suspension service procedures should be followed during replacement.
