The Speedmaster Ford SB 289 302 351 Windsor Rocker Stud Girdle Kit is a specialized engine component designed to secure and align the rocker studs on small-block Windsor Ford engines. This red girdle kit includes 7/16" polylock nuts, providing a complete fastening solution for rocker arm assembly applications.
