Engine & Performance Warehouse Aluminum Roller Rocker Arms

Engine & Performance Warehouse Aluminum Roller Rocker Arms are valvetrain components for overhead valve (OHV) engines. Each rocker arm carries the pushrod's motion to the valve, so the valve opens as the camshaft intends. These aluminum roller rockers suit street, performance and racing engine builds and replace stock stamped steel or cast rocker arms.

Key Features:

• Aluminum construction: It is lighter than steel or cast iron. That cuts reciprocating valvetrain weight, which helps in higher-revving applications.
• Roller tip design: A roller at the valve contact point replaces sliding contact. It reduces friction, heat and uneven wear on the valve tip and valve guide.
• Lower friction: Less friction at the valve stem supports smoother valvetrain operation and higher engine speeds.
• Performance upgrade: Roller rocker arms are a popular upgrade for engine builders who want better valvetrain durability and more precise valve control.

Engine & Performance Warehouse offers this roller rocker arm line in several configurations. Select the variant that matches your engine and valvetrain setup.
