The Speedmaster PCE213.1016 is a lightweight steel full spool designed for the iconic Ford 9-inch rearend, featuring a robust 40-spline configuration for maximum torque transfer and drivetrain strength under high-performance racing conditions. Built to replace a conventional differential, this full spool locks both axles together for consistent, equal power delivery — ideal for drag racing and competitive motorsports applications.
Engineered to fit the Ford 9-inch housing with a 2.25-inch bearing, this spool delivers the reliability and durability demanded in performance builds. Its lightweight steel construction helps reduce rotational mass while maintaining the structural integrity needed to handle serious horsepower, making it a smart upgrade for dedicated race vehicles.
