SBC Rocker Arms - 1.6 Ratio 3/8 Stud

The SBC Rocker Arms – 1.6 Ratio 3/8 Stud from SHARP ROCKERS are a vital upgrade for small-block Chevrolet engine builders and performance enthusiasts who demand reliable valve actuation. These rocker arms are designed to replace factory units in classic muscle cars, street rods, and high-performance builds where precise valve timing and durability are essential.

The 1.6:1 ratio provides a mechanical advantage that enhances valve lift characteristics, making them suitable for cam profiles intended for aftermarket heads and intake manifolds on any SBC platform. The design features a 3/8-inch stud configuration, the industry-standard fastening method for SBC applications, ensuring stable rocker geometry and consistent pushrod alignment under load. Constructed from precision-cast steel, these rocker arms deliver consistent tolerances across the entire set, minimizing valve lash variability and wear.

These rocker arms are compatible with any small-block Chevrolet engine equipped with 3/8-inch stud holes, including 283, 302, 305, 327, 350, and 400 cubic-inch blocks. Whether you're building a numbers-matching restoration or a high-performance engine, these rocker arms strike an excellent balance between aggressive valve opening rates and reliable street-driven performance.
