Detailed Description

StrongArm 6845 is a pressurized lift support built for BMW X3 models from 2011 through 2017. The cylinder is custom engineered for the application, with a steel outer body, 19.0 mm cylinder outside diameter, and an 8.0 mm inner shaft diameter. Its 145.0 force rating and 8.75-inch stroke help maintain steady support and controlled lift action for the hood, hatch, or rear glass where equipped. This part cross-references Gates 6845 for the same application. StrongArm 6845 is a direct replacement choice for BMW X3 lift support service when the original strut has weakened, lost pressure, or no longer holds position reliably.

Common Problems This Part Can Solve

• Hood, hatch, or rear glass that drops instead of staying open
• Slow or uneven lift action during opening
• Loss of gas pressure in the original support
• Excess effort needed to raise the panel
• Inconsistent holding force in BMW X3 lift support service

Installation Notes and Tips

Replace lift supports in pairs to maintain balanced support and even operating force. Confirm end fittings match the vehicle before installation: this unit uses a 10 mm nylon ball socket on one end and a 16-degree angled nylon ball socket on the other. Verify the compressed and extended lengths against the original support before removal. For BMW X3 hood lift support replacement or BMW X3 hatch lift support replacement, compare the original part number and mounting style to ensure proper fitment.

StrongArm lift supports are custom engineered and manufactured beyond industry standards to support smoother operation and longer service life. Part number 6845 is built as a specific-fit replacement for the listed BMW X3 applications.
