Product Details

The FCS brand line focuses on replacement support components for body and compartment service, and FCS 86169 is specified for the trunk lid on 2005-2011 Cadillac STS models. The measured compressed, extended, and stroke lengths help match the original lift support geometry so the trunk lid opens and stays positioned as intended during normal use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Trunk lid that drops instead of staying open
• Weak or slow trunk lid lift action
• Uneven or inconsistent trunk lid support
• Difficulty accessing the cargo area on a Cadillac STS
• Worn gas strut performance from age and repeated use

Installation Notes and Tips

Verify the vehicle is a 2005-2011 Cadillac STS before ordering. Compare the existing support’s compressed length, extended length, and stroke length to confirm the replacement matches the trunk lid geometry. Inspect the mounting points and surrounding hardware for wear or damage before installing the new support. After installation, cycle the trunk lid several times to confirm smooth operation and proper hold-open function.

Quality Assurance

FCS 86169 is a replacement trunk lid lift support built to match the listed application dimensions for the Cadillac STS. Use the fitment data and measured lengths to confirm correct application before installation.
