Detailed Description

StrongArm 4051 is a replacement lift support engineered for the BMW Z3 platform from 1999 through 2002. It is built to match the application-specific mounting points and operating dimensions needed for reliable hood, hatch, or rear window glass support. The 19.0 mm cylinder outside diameter and 8.0 mm inner shaft diameter support stable movement, while the pressurized design helps maintain consistent lift performance over time.

Installation Notes and Tips

Verify the existing support’s compressed length, extended length, and 10mm ball socket end style before ordering.
