The Speedmaster Ford SB 289/302 Windsor Steel Main Girdle (PCE288.1012.01) is a precision-engineered engine block component designed to reinforce and support the crankshaft main bearing saddles on small-block Windsor engines. Built from steel for maximum strength and durability, this main girdle helps stabilize the crankshaft under load and reduce bearing wear during high-rpm operation.
This girdle is engineered as a direct replacement or upgrade component for Ford 289, 302, and compatible Windsor-series engines. It bolts to the bottom of the engine block to provide additional bracing for the main bearing journals, making it ideal for performance builds, street applications, and engine rebuilds where crankshaft support and longevity are priorities. The steel construction ensures reliable performance in both stock and modified engine configurations.
