The SBC Rocker Arm Set - 1.6 Ratio 3/8 Stud from Elgin is designed for small-block Chevrolet builds that require reliable valve actuation and power delivery across the RPM range. This rocker arm set serves as the essential link between the camshaft and the intake/exhaust valves, controlling valve lift, duration, and timing precision.
The 1.6 rocker arm ratio enhances camshaft lift by multiplying valve opening distance, improving volumetric efficiency without the need for aggressive valve spring pressures that could stress the valvetrain. Elgin's manufacturing emphasizes dimensional accuracy and consistent hardening, ensuring durability and performance under repeated shock loads.
This rocker arm set is ideal for small-block Chevrolet engine builders looking to upgrade from worn factory rockers or transition to aftermarket camshaft packages. The 3/8-inch stud design provides compatibility with most SBC cylinder heads and stud girdles, making it a versatile choice for various engine applications.
