Detailed Description

The FCS 84545 is a trunk lid lift support for BMW rear body applications. It is matched to the listed compressed, extended, and stroke dimensions to support proper trunk lid travel and holding force on compatible vehicles. This part number, 84545, is listed for 1991-1992 BMW 850i, 1994-1995 BMW 850CSi, 1994-1997 BMW 840Ci, and 1993-1999 BMW 850Ci models.

FCS 84545 is a practical replacement when the original trunk support no longer maintains lift or control. For buyers searching for a BMW 850Ci trunk lid lift support, BMW 840Ci rear lift support, or BMW 850i trunk strut replacement, this part matches the specified fitment and dimensional profile.

What It Helps Fix

• Trunk lid that drops instead of staying open
• Weak or inconsistent lift support action
• Hard-to-open rear compartment lid
• Trunk lid movement that feels uncontrolled
• Wear-related loss of support on the rear lid

Installation Notes and Tips

Verify the existing support length and mounting style against the listed dimensions before installation. Compare the removed part to FCS 84545 to confirm the compressed length, extended length, and stroke length match the vehicle’s trunk lid hardware. Install only on the rear trunk lid position listed in the fitment data.

Quality Assurance

FCS identifies this part by application-specific fitment and dimensional specifications for the listed BMW models. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
