Trac-Lock 8-Inch 3.55 Gear Ratio 28-Spline LSD Kit

The F8-355-PGBK is an 8-inch Trac-Lock limited-slip differential designed as a performance upgrade or replacement for Ford 8-inch rear-end assemblies. By utilizing a limited-slip mechanism, this unit helps distribute power to both rear wheels, enhancing traction and stability during acceleration compared to a standard open differential. This differential assembly features a 3.55 gear ratio and is machined for a 28-spline axle fitment. It is intended for use in Ford 8-inch rear-end setups to assist with re-gearing or repairing drivetrain components. Ensure that your specific axle housing and axle shaft spline count match the 28-spline specification before beginning installation. Professional installation is recommended for this component due to the precision required for differential setup, including backlash adjustment and gear pattern verification. This kit is designed for Ford-specific 8-inch rear axles and is not compatible with other axle sizes or configurations.
