The Speedmaster 1-209-003 is an aluminum oversize pinion support designed specifically for the iconic Ford 9-inch differential with a standard case. Built to accommodate a 35-spline pinion, this upgrade is engineered for high-performance and racing applications where stock pinion support simply isn't enough to handle increased power and torque loads.
Constructed from aluminum for a weight-conscious yet durable solution, this oversize pinion support helps improve pinion rigidity and reduce deflection under hard acceleration. A direct-fit replacement for standard Ford 9-inch cases, it's an ideal choice for enthusiasts and builders looking to strengthen their rear axle assembly for street, strip, or off-road use.
