The Speedmaster PCE288.1021 Main Girdle is designed specifically for the Ford 351 Cleveland engine, delivering added rigidity to the bottom end by tying the main bearing caps together for improved block stability under high-performance conditions. Crafted from anodized aluminum, this girdle resists corrosion while keeping weight to a minimum — a smart upgrade for any 351C build aimed at increased power output or durability.
Sold as the girdle only, this component is an ideal choice for engine builders looking to reinforce their Ford 351 Cleveland short block without a complete kit. Whether you are building a street-performance or dedicated racing application, the Speedmaster main girdle helps maintain proper main cap alignment and reduces flex during hard acceleration.
