Product Details

FCS 84780 is a tailgate lift support intended for vehicles that use a gas-charged support to assist tailgate movement. The listed compressed length, extended length, and stroke length are the key dimensions used to match the support to the correct tailgate geometry and operating range. For buyers searching for a tailgate lift support for FCS 84780, or an OE-style replacement tailgate support with the same travel specifications, these measurements are the primary reference points.

The FCS brand line focuses on replacement parts for body and chassis service, and this tailgate lift support follows that approach with application-specific sizing. If you are sourcing a tailgate lift support for a Chevrolet Silverado or GMC Sierra tailgate repair, verify the mounting points and length requirements against the original support before ordering. Part number 84780 is also useful when cross-checking catalog listings for the same application.

What It Helps Fix

• Tailgate that drops too quickly when opened
• Tailgate that will not stay supported in the open position
• Weak or worn lift support performance
• Uneven tailgate movement during opening or closing
• Noise or binding caused by a failing support

Installation Notes and Tips

Confirm the compressed length, extended length, and stroke length against the original support before installation. Inspect the tailgate mounting points, brackets, and pivot hardware for wear or damage, since a new support will not correct bent or loose attachment points. For fitment-based searches, use the exact vehicle listing and position data from the catalog when matching this part to a Chevrolet Silverado or GMC Sierra application. Part number 84780 should be matched to the original support number whenever possible.
