ARP Pro Series Rocker Arm Stud Thread

ARP Pro Series rocker arm studs are high-strength engine fasteners designed to replace factory rocker arm studs or bolts in performance and racing engines. Also known as rocker studs or rocker arm mounting studs, they hold the rocker arm assembly securely in place under the higher valvetrain loads that come with aftermarket camshafts, stiffer valve springs and increased RPM.

Key Features:

• Made by ARP, a well-known maker of performance fasteners for racing and high-performance engines
• Built from high-strength alloy steel for durability under repeated, heavy valvetrain loading
• Rolled threads for strength and fatigue resistance
• Precision machining for consistent fit and reliable clamp load
• Offered in multiple configurations to suit different engine families and applications

Pro Series studs give street performance, racing and high-output engine builders a dependable upgrade over stock hardware. They help keep valvetrain geometry stable and the rocker arms secure. Choose the specific variant that matches your engine and rocker arm setup.
