Detailed Description

StrongArm Part Number 6651 is a trunk lid lift support built for select BMW 3 Series and M3 applications. It is engineered as a specific-fit replacement with the correct compressed length, extended length, stroke, and end fittings for direct trunk lid support. The 78.0 force rating helps maintain steady opening and closing action, while the steel cylinder construction supports long-term durability. This StrongArm 6651 lift support is a practical replacement when the original trunk support no longer holds the lid securely.

Compatible With 2006-2013 BMW 328i, 328i xDrive, 328xi, 330i, 330xi, 335i, 335i xDrive, 335is, 335xi, 335d, 325i, 325xi, 330i, 330xi, and M3 trunk lid applications. The StrongArm 6651 is also referenced by AMS Automotive 6651 and other OE-style interchange numbers for the same fitment family.

What It Helps Solve
