ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
When building a high-performance Small Block Ford, valvetrain stability is non-negotiable. The Auto Racing Products (ARP) Pro Series Rocker Arm Stud Kit is engineered to provide the clamping force and rigidity required for aggressive camshaft profiles and high-RPM operation. These studs are manufactured from premium 8740 chromoly steel, heat-treated to ensure superior tensile strength and fatigue resistance compared to standard factory hardware.
These studs are designed for builders who demand consistency. The 7/16-inch diameter provides increased stiffness, effectively reducing rocker arm deflection under heavy valve spring pressure. Whether you are running a street-strip machine or a dedicated track car, these studs ensure your valvetrain geometry remains locked in place. The precision-rolled threads offer superior engagement, preventing galling and ensuring accurate torque readings every time you service your engine. Trust your engine build to the industry standard in fastener technology found here at GGCRACING.
