SBC H/E Alum. R/A's - 1.5 Ratio 3/8 Stud

The COMP CAMS SBC High Energy Aluminum Rocker Arms with 1.5 Ratio and 3/8 inch stud mount deliver the precision valve control that small block Chevy engine builders require for consistent performance across a range of applications. This set of 16 rocker arms features die-cast aluminum construction paired with a full roller design, reducing friction at the valve train and enabling more reliable valve actuation across engine speeds.

The 1.50 ratio specification increases valve lift compared to a stock 1.2 ratio, translating to greater valve opening at the cylinder head for improved air and fuel mixture flow during the intake and exhaust cycles. The 3/8 inch stud mount design ensures straightforward installation on standard small block Chevy heads. High energy die-cast construction provides durability under sustained performance conditions while maintaining dimensional consistency across the full set, critical for balanced engine operation and minimized valve lash variation.

These rocker arms suit engine builders and enthusiasts optimizing small block Chevy platforms for street, strip, or competition use where improved valve train efficiency and reduced friction losses matter. Whether upgrading from stock stamped steel rockers or replacing worn components in an existing performance build, the combination of die-cast strength, aluminum weight savings, full roller design, and verified 1.5 ratio geometry delivers the mechanical advantage needed for predictable, repeatable engine behavior.

COMP CAMS remains an established supplier within the small block Chevy performance aftermarket, and this rocker arm set reflects the precision and component quality expected from a manufacturer focused on valve train systems and engine architecture.
