Fitment Details

Fits 1979-1985 Mazda RX-7, N/A, spoiler-equipped trunk lid.

This FCS 84709 trunk support is matched to the Mazda RX-7 platform for the listed years and body configuration. The length and stroke specifications are the key dimensions to verify when replacing a worn lift support, since they determine the open height, travel, and closing feel of the trunk lid.

FCS is the brand line identified for this part, and 84709 is the reference number to use when confirming the correct rear lift support for your Mazda RX-7. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Trunk lid that drops instead of staying open
• Weak or inconsistent lift support pressure
• Reduced opening height on a spoiler-equipped trunk lid
• Slow or uneven trunk lid movement
• Replacement for a worn rear support on a Mazda RX-7

Installation Notes and Tips

Confirm the compressed length, extended length, and stroke length against the existing support before installation. Verify that your vehicle is a 1979-1985 Mazda RX-7 with a spoiler-equipped trunk lid, since fitment is specific to that configuration. Compare the mounting points and overall dimensions to the removed unit to ensure the replacement matches the original travel range.

Quality Assurance

FCS 84709 is listed with exact dimensional specifications for fitment verification, including compressed length, extended length, and stroke length. Use those measurements to confirm the correct replacement for your Mazda RX-7 trunk lid support.
