Yukon Gear YPKF9-PC-01 is a replacement friction plate for compatible Ford 8-inch and 9-inch Trac-Lok limited-slip differentials. Designed for late-style 4-tab clutch configurations, this individual plate is used when servicing worn clutch components inside an existing Trac-Lok carrier.
The supplied application data identifies YPKF9-PC-01 as a graphitic friction plate with a waffle-pattern friction surface and 4-tab design. It is intended as an individual service component rather than a complete clutch kit, making it useful when a specific friction plate requires replacement during differential repair or rebuilding.
Ford 8-inch and 9-inch Trac-Lok differentials were used across a broad range of Ford, Lincoln, and Mercury vehicles. Compatible applications include Mustang, Bronco, F-Series, Torino, Ranchero, Thunderbird, Cougar, Econoline, and related platforms using the correct late-style 4-tab Trac-Lok clutch configuration.

About Yukon Gear Trac-Lok Friction Plates:
Yukon Gear & Axle Trac-Lok friction plates are individual replacement components used to service clutch-type Ford limited-slip carriers. Application-specific plates such as YPKF9-PC-01 allow a worn friction component to be replaced individually when the remaining carrier and clutch components are still serviceable. They are useful for restoration, performance, truck, van, and general differential repair involving compatible late-style Ford 8-inch and 9-inch Trac-Lok assemblies.
