Product Overview:

Key Features:

• Highest Strength-to-Weight Ratio: Made from high-grade Billet steel, each rocker arm is heat-treated for enhanced durability.

• High-Load Bushing with Pressurized Oiling: Ensures efficient oil flow from lifters through pushrods to the adjusting screw, maintaining optimal lubrication and reducing friction.

• Enhanced Pushrod and Roller Interface: Designed to withstand higher abuse and increase RPM capability.
• Advanced Adjusting Screws: Uses resilient 3/8 ball adjusting screws, providing better oil reserve and reducing galling upon startup.
• Large Roller Wheel: The .571″ roller wheel with a .275″ pin supports higher engine speeds and increased cylinder pressure.
