Speedmaster Ford SB 289 302 351 Windsor Rocker Stud Girdle - Black PCE259.1007.01

The Speedmaster Ford SB rocker stud girdle is a precision-engineered engine component designed for small-block Ford Windsor engines, including 289, 302, and 351 cubic-inch models. This girdle-only assembly (rocker arm components sold separately) provides critical support and alignment for rocker studs, maintaining proper valve train geometry and reducing deflection under high RPM operation.

Constructed with a black finish for corrosion resistance, this OEM-style rocker stud girdle integrates seamlessly into stock or modified Windsor engine builds. It is commonly used in restoration projects, performance upgrades, and daily-driver engine rebuilds where maintaining authentic small-block Ford valve train architecture is essential. The girdle's rigid design helps preserve rocker arm geometry and extends component life, making it a reliable choice for both street and engine-shop applications.
