Detailed Description

The FCS 86157 is a back glass lift support built for rear glass lift applications on full-size GM SUVs and related models. Its 11.5-inch compressed length, 19.76-inch extended length, and 8.27-inch stroke length provide the dimensional match needed for proper rear glass movement and hold-open performance. This part number is commonly searched as FCS 86157 for Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon rear glass service.

FCS is the brand line identified for this part, and this product is listed specifically as a back glass lift support rather than a general-purpose strut. If you are replacing a worn rear glass support on a 2007-2014 Cadillac Escalade or a 2007-2014 Chevrolet Tahoe, FCS 86157 gives you a fitment-specific option for the rear glass opening system.

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

Common Problems This Part Addresses

• Rear glass that drops instead of staying open
• Weak lift support force when opening the back glass
• Slow or uneven rear glass movement
• Rear glass that no longer holds in the raised position
• Wear-related loss of support on high-use liftgate glass

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, and model, especially on Escalade, Suburban, Tahoe, and Yukon variants where rear glass hardware can vary by body style and trim.

Inspect the mounting points and surrounding liftgate hardware for wear or damage before installing the replacement support. Match the existing rear glass orientation and confirm smooth operation after installation.

Quality Assurance

FCS identifies this part as a fitment-specific back glass lift support for the listed GM applications. Use the published dimensions and vehicle coverage to confirm the correct replacement before service.
