Fitment Details

The FCS 86156 is a rear liftgate support for full-size GM SUVs and related models. It is sized to provide the opening and closing travel needed for the liftgate on the listed Cadillac Escalade, Chevrolet Tahoe, Chevrolet Suburban, and GMC Yukon platforms. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Liftgate that drops instead of staying open
• Weak or slow rear hatch movement
• Liftgate that feels heavy to raise
• Uneven or inconsistent liftgate support
• Rear hatch support wear on high-use vehicles

Installation Notes

Verify the compressed length, extended length, and stroke length against the original support before installation. Confirm vehicle year, make, and model carefully, since fitment varies across Escalade, Tahoe, Suburban, and Yukon applications. Replace worn lift supports in a stable, supported liftgate position and compare the mounting points to the original unit before removal.

Quality Assurance

FCS 86156 is cataloged as a body and door component for the specified GM applications. Its dimensional specifications provide the key reference points for selecting the correct rear liftgate support for your vehicle.
