Elgin Small Block Chevy Rocker Arm Ratio Stud

Elgin Small Block Chevy stud-mount rocker arms (also called ratio rocker arms) are valvetrain components for small block Chevy engines. Each rocker arm transfers camshaft motion from the pushrod to the valve. The ratio you choose sets how far the valve opens for a given amount of lifter travel. These rocker arms suit stock rebuilds and performance upgrades.

Key Features:

• Stud-mount design: Works with the rocker stud setup used on small block Chevy cylinder heads.
• Ratio options: Several rocker ratios are available, so you can match the valve lift to your cam and engine build.
• Steel construction: Built for durability under constant valvetrain loads.
• Long-slot and roller-tip styles: Elgin offers both. Roller-tip designs reduce friction at the valve tip.
• Quality manufacturing: Elgin Industries has made engine components since 1919.

Choose the child option that matches your stud diameter, rocker ratio, and style. Elgin rocker arms are a dependable way to restore or improve valvetrain performance in a small block Chevy build.
