Description

PRW Main Cap Stud Kit # 1000323 is made from premium grade Custom 4135 Steel, specially heat-treated to 180,000 psi for superior strength. The studs are centerless ground after heat treatment for perfect alignment and thread rolled for improved fatigue strength. This kit helps eliminate main cap walk and protects engine block threads, providing a strong foundation for high horsepower builds. It includes hardened parallel-ground washers and quality 12-point nuts.
