Product Details

The Monroe Max-Lift Lift Support line focuses on OE-style replacement for vehicle compartments that rely on gas pressure to open and hold securely. Part number 900144 uses matched dimensions and mounting codes to support proper installation on the specified BMW trunk lid applications. Monroe 900144 is a practical replacement when the original support no longer holds the lid open or loses lift force.

Common Issues It Can Solve

• Trunk lid drops instead of staying open
• Weak or inconsistent lift assistance
• Slow or uneven opening action
• Loss of holding force from a worn gas strut

Installation Notes

Verify the compressed length, extended length, travel length, and mounting codes before installation. Match the existing support configuration to the listed fitment and confirm the trunk lid application uses the same E upper and lower mounting codes. Replace worn supports in pairs only when the vehicle setup calls for it.

Quality Assurance

Monroe Max-Lift supports are engineered to fit and perform as original equipment units for the listed applications.
