Yukon Gear YPKF9-P-28-REB is a differential carrier rebuild and internal gear kit for compatible Ford 8-inch and 9-inch Trac-Lok positraction units using 28-spline axles. Designed for comprehensive carrier service, this kit provides the primary spider gears and related internal hardware needed when rebuilding a worn Trac-Lok differential.
The supplied component list includes two 28-spline side gears, four pinion gears, a cross-pin shaft, clutch hub, roll pin, and spider gear thrust washers. This combination makes YPKF9-P-28-REB useful when multiple internal carrier components require replacement while the main differential carrier remains suitable for rebuilding.
Ford 8-inch and 9-inch Trac-Lok differentials were used across a broad range of classic Ford, Lincoln, and Mercury cars, trucks, vans, and performance platforms. Compatible applications include Mustang, Bronco, F-Series, Fairlane, Falcon, Galaxie, Torino, Ranchero, Thunderbird, Cougar, Econoline, and related models using the correct 28-spline Trac-Lok carrier.
