FCS 84405 Back Glass Lift Support

Back Glass Lift Support for Select Volkswagen and Ford Models

FCS 84405 is a back glass lift support built for rear glass applications that use a gas-charged support to hold the liftgate glass in position. With an 11.57-inch compressed length, 19.72-inch extended length, and 8.15-inch stroke, it matches the travel needed for specific hatch and liftglass setups.

Compatible With 1985-1995 Volkswagen Golf with defroster, plus select Ford Fairmont, LTD, Pinto, and Mercury Marquis, Zephyr, and Bobcat applications. The FCS brand line focuses on direct-fit replacement support components for body and glass service, and part number 84405 follows that OE-style replacement approach.

Detailed Description

FCS 84405 is specified for rear glass lift support service where the original support has lost pressure or no longer holds the back glass securely. The listed dimensions help confirm fitment for the intended hatch or liftglass geometry, including the Volkswagen Golf application with defroster and the classic Ford and Mercury body styles shown in the fitment data. If you are replacing a worn back glass lift support on a Volkswagen Golf, Ford Pinto, or Mercury Bobcat, this part number provides a direct reference for the correct application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Back glass that will not stay open
• Weak or slow liftglass support action
• Rear glass dropping unexpectedly
• Loss of support pressure in hatch glass service
• Fitment issues caused by an incorrect support length

Installation Notes and Tips

Verify the compressed length, extended length, and stroke length against the original support before installation. Confirm the vehicle application by year, make, model, and rear glass configuration, especially on the 1985-1995 Volkswagen Golf with defroster. Compare the mounting points and overall travel to the removed part to ensure the replacement matches the original geometry.
