ARP 334-7201 Pro Series Rocker Arm Studs - 16-Piece Set

ARP Pro Series rocker arm studs are precision-engineered components designed to eliminate the geometry inconsistencies and wobble associated with standard rocker studs. These professional-grade studs are manufactured to exacting tolerances, with concentricity held within .005 T.I.R. thread pitch to thread pitch, ensuring they thread in straight and true every time.

Key Features:

• Premium grade 8740 chrome moly steel construction
• Heat-treated to 200,000 psi tensile strength for competition durability
• Precision concentricity within .005 T.I.R. for consistent rocker geometry
• Exact lengths engineered for positive seating
• Extra-large radius base provides superior resistance to flex
• Tip ground flush for optimum adjuster seating
• 16-piece set for complete engine builds

Application:

Designed specifically for competition applications where reliability and precision are critical. These Pro Series studs deliver the strength and consistency demanded by high-performance and racing engines.

Important Installation Notes:

• Not compatible with OEM-style self-locking nuts
• Must be used with ARP's patented Perma-Loc adjusters
• Verify optimal stud length for your specific application, especially when using aftermarket pushrods, valves, or modified valve train geometry
• When using longer-than-stock components, you may need to raise the installed height of the rocker arm to maintain proper geometry

ARP rocker arm studs are trusted by engine builders and racers worldwide for their exceptional quality, precision manufacturing, and proven performance under extreme conditions.
