Product Details

Arnott Remanufactured AS-3374 is rebuilt from an OE BMW rear right strut core, then inspected, steam cleaned, and media blasted to bare metal before reassembly. The damper is recharged with new shock oil, worn internal components are replaced, and the unit is finished with corrosion-resistant paint. The design retains auto-leveling and OE damping functionality for BMW 7-Series models equipped with air suspension.

This part cross-references BMW 37106874594 and 37107915954 for the same application.

Common Problems This Strut Can Address

• Rear suspension sag on the right side
• Air spring leakage from a worn bladder or seals
• Excessive bouncing, harshness, or reduced damping control
• Warning lights related to ride height or leveling performance
• Uneven rear ride height on BMW 7-Series air suspension systems

Installation Notes

Verify rear right fitment by year, model, and drivetrain before installation. This strut uses a loop/eyelet lower mount and stud-style upper mount, with an upper mounting isolator included. Mounting hardware is not included. After installation, inspect the air line connection, confirm proper ride height calibration, and check for leaks before returning the vehicle to service.

Quality Assurance

Each AS-3374 strut is dyno tested and functionally tested to confirm damping performance and air suspension operation. Arnott remanufactures this unit to OE-style standards for BMW 7-Series rear suspension service.
