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.
The valve train is the heart of your engine's performance, and the Auto Racing Products (ARP) Rocker Arm Stud Kit is designed to keep it running smoothly. These high-performance studs feature a 7/16-14 base thread and a 3/8-24 top thread, providing a robust mounting point for your rocker arms. Crafted from premium chromoly steel, these studs are built to handle the intense vibration and heat found in high-RPM racing environments.
When you increase valve spring pressure or camshaft lift, stock rocker studs can flex or snap, leading to catastrophic engine failure. These ARP studs offer significantly higher tensile strength, ensuring your rocker geometry remains consistent throughout the entire RPM range. This pair is perfect for those needing to replace damaged studs or performing a partial valve train upgrade. With a precise 1.750-inch effective length, they provide the clearance needed for most aftermarket rocker arm configurations. Elevate your engine's reliability and performance with top-tier components sourced from GGCRACING.
