This Small Block Chevy aluminum roller rocker arm set features a 1.6:1 ratio and is designed for 7/16" rocker studs, making it an ideal upgrade for high-performance SBC applications. The lightweight aluminum construction reduces valvetrain mass while providing the strength and stability needed for high-RPM operation.

These are Straub Tech–modified rocker arms, engineered to optimize roller-to-valve stem contact and sweep on aftermarket 23-degree SBC cylinder heads, including VEPR, AFR, Dart, Brodix, and Edelbrock castings that utilize longer-than-OEM valve lengths. The result is improved valvetrain geometry, reduced guide wear, and more consistent valve motion.

Each set includes standard-length poly-locks for secure and repeatable valve adjustment.
