SBC Roller Rocker Arm Set 1.6 Ratio 7/16 Stud

The SBC Roller Rocker Arm Set 1.6 Ratio 7/16 Stud from Air Flow Research is designed for small-block Chevrolet builders looking to enhance their engine's performance. This set is ideal for street performance and mild competition builds, where optimizing valvetrain efficiency can lead to significant horsepower gains.

Featuring precision-machined bodies and hardened steel rollers, these roller rocker arms reduce friction losses compared to traditional stamped steel designs. The 1.6 ratio configuration improves valve opening velocity, contributing to better volumetric efficiency and cylinder fill. The roller bearing races further minimize parasitic drag, enhancing overall engine performance.

This complete set ensures consistent valve timing across all eight cylinders, making it suitable for high-RPM conditions. The 7/16-inch stud diameter aligns with original SBC specifications, ensuring compatibility with standard pushrod geometry and existing cylinder head drilling, making it a reliable choice for performance enthusiasts.
