SBC H/E Alum. R/A's - 1.6 Ratio 7/16 Stud

The SBC H/E Alum. R/A's - 1.6 Ratio 7/16 Stud from COMP CAMS are high-energy rocker arms engineered for small-block Chevy engines demanding reliable valve actuation and durability. These full roller rocker arms are designed for enthusiasts and engine builders who need precise, repeatable performance without the complexity of more exotic valvetrain components. The 1.6:1 ratio provides a proven mechanical advantage that balances lift multiplication with reasonable spring pressures, making this set ideal for street and moderate performance applications where consistent reliability matters.

Constructed from aluminum for weight savings, these rocker arms feature full roller technology that minimizes friction and wear on the camshaft lobe and pushrod interface. The die-cast aluminum construction maintains structural integrity while reducing overall valvetrain mass—a critical factor in engine responsiveness and longevity. The 7/16-inch stud mount design provides a secure, industry-standard attachment point compatible with existing small-block Chevy cylinder heads, while the 1.6 ratio delivers increased valve lift compared to 1.5:1 designs without requiring cam profile changes or extensive head modifications. Set of 16 pieces covers a complete small-block Chevy engine, with each arm precision-manufactured to COMP CAMS' exacting tolerances.

These rocker arms suit engine builders, performance enthusiasts, and restoration shops building or refreshing small-block Chevy engines from 262 to 400 cubic inches. Installation requires compatible pushrods, valve springs rated for the intended engine output, and proper stud clearance verification before final assembly. The full roller design significantly extends service life compared to standard stamped arms, offering long-term value in both street performance and track-focused builds. Proper valve lash adjustment and rocker arm geometry verification ensure optimal cam profile utilization and engine reliability.
