Arnott AS-3371 Air Suspension Strut - Front Left

OE Remanufactured Front Left Air Strut

Arnott AS-3371 is a remanufactured front left air suspension strut for select BMW 7-Series models with rear-wheel drive. It is built to restore OE-style ride control, auto leveling, and damping performance on the 2016-2021 BMW 7-Series platform, with 2022 BMW 740i and 745e front left coverage noted in the fitment data.

The Arnott Remanufactured line focuses on rebuilding original suspension components to factory-style operation. For this application, the strut is cleaned, inspected, and rebuilt with new wear components, then tested for function and damping consistency before it is finished with corrosion-resistant paint.

Detailed Product Overview

AS-3371 is remanufactured from an OE BMW front left air suspension strut and rebuilt with new high-performance shock oil, replaced piston and rod guides, and a new seal pack. The damper and coil are dyno tested and functionally tested to verify OE-level operation. This part number, Arnott AS-3371, is engineered for BMW 7-Series vehicles with rear-wheel drive and retains the vehicle’s auto leveling and OE damping functionality.

This part cross-references BMW 37106877055 and 37106877553 for the same application.

What This Strut Helps Address

• Front left suspension sag or uneven ride height
• Loss of damping control over bumps and road joints
• Air spring leakage from a worn bladder or fittings
• Noise or harshness caused by worn internal strut components
• Ride-quality changes tied to aging OE air suspension hardware

Installation Notes

Verify vehicle configuration before ordering: this strut is listed for rear-wheel-drive BMW 7-Series applications and front left position only. Mounting hardware is not included. Transfer or reuse any vehicle-specific components as required by the service procedure, and confirm all air line connections are clean and properly seated before final calibration.

Quality Assurance

Each Arnott remanufactured strut is rebuilt, inspected, and tested before release. The unit is media blasted to bare metal, recharged with new shock oil, fitted with new wear components, and checked for function and damping performance to support OE-style operation on the BMW 7-Series platform.
