The Speedmaster PCE259.1006.03 Rocker Stud Girdle Kit is engineered for Ford small-block 289, 302, and 351 Windsor engines, delivering added valvetrain stability by linking and bracing the rocker studs together. Finished in a bold red, this kit helps reduce rocker stud flex and deflection under high-RPM and high-lift camshaft operation, contributing to more consistent valve timing and improved overall engine reliability.
This complete kit includes 7/16" polylock nuts, providing a secure, positive lock on your rocker studs to prevent loosening under demanding conditions. Designed as a direct-fit solution for Ford SB 289, 302, and 351 Windsor applications, this girdle kit is an ideal upgrade for street performance and racing builds looking to enhance valvetrain integrity without extensive modification.
