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.
Specifically designed to fortify the exhaust side of your valvetrain, the ARP Pro-Series Rocker Arm Stud Kit offers targeted strength and stability where it's often needed most. These high-performance studs are crucial for maintaining precise valve control under the intense heat and pressure of exhaust cycles, preventing stud flex and ensuring consistent rocker arm geometry. Each stud is precision-machined from premium chromoly steel, delivering superior tensile strength and fatigue resistance for extreme engine conditions.
This specialized kit includes eight studs, perfect for engines where only the exhaust valvetrain requires a specific length or upgrade. With a 7/16-14 inch base thread for secure cylinder head mounting and a 7/16-20 inch top thread, these studs provide broad compatibility with various aftermarket rocker arms. The 2.000-inch effective stud length is ideal for applications requiring a longer stud to accommodate specific rocker arm designs or valvetrain geometries on the exhaust side.
Trust ARP Pro-Series for the critical components of your valvetrain. This exhaust-specific kit provides the focused upgrade needed to ensure your engine performs flawlessly, even under the most demanding conditions. Available now at GGCRACING.COM.
