SBC H/E Alum. R/A's - 1.5 Ratio 7/16 Stud

The COMP Cams SBC High Energy Aluminum Rocker Arms with 1.5 Ratio and 7/16" Stud Mount (Set of 16) deliver dependable valve actuation for small-block Chevy engines built for sustained performance. These die-cast aluminum rocker arms are engineered to handle the demands of both street and competition applications where precise valve timing and consistent lift are critical to engine reliability and output.

The 1.5:1 mechanical advantage ratio provides a proven balance between valve lift multiplication and pushrod geometry compatibility across a wide range of small-block Chevy platforms. Full-roller design minimizes friction during valve train operation, reducing wear on valve stems and lash adjusters while promoting cooler operating temperatures. The 7/16" stud mount design integrates directly into factory and most aftermarket cylinder head configurations without requiring extensive modification. Aluminum construction keeps reciprocating mass low, allowing higher engine speeds without sacrificing stability or control.

This 16-piece set covers a complete small-block Chevy valve train (eight intake and eight exhaust rocker arms). Engine builders and enthusiasts restoring or upgrading carbureted and fuel-injected small-block applications rely on COMP Cams rocker arms for consistent performance across street, strip, and road-course use. The High Energy die-cast construction provides the durability necessary for sustained RPM ranges without the weight penalty of solid steel alternatives.

Small-block Chevy rocker arm selection depends on matching the ratio, stud diameter, and material to your cylinder head casting and intended engine power level. COMP Cams' High Energy line represents a standard reference point in the market, trusted across Chevrolet performance segments for over four decades.
