Rocker Arm - SBC 1.5 Ratio 7/16 Stud

The Rocker Arm - SBC 1.5 Ratio 7/16 Stud from CROWER is a precision-engineered component designed for small block Chevy (SBC) engine builders and performance enthusiasts. This full roller rocker arm is engineered to maximize valve lift efficiency and improve engine responsiveness across a wide RPM range. Whether you're building a street performance engine, a weekend track car, or a dedicated racing application, this rocker arm delivers the mechanical advantage needed to optimize camshaft performance and increase horsepower gains.

The 1.5:1 ratio design multiplies valve lift by 50 percent, translating camshaft lift directly into enhanced cylinder head flow characteristics. Constructed from durable stainless steel, this rocker arm resists corrosion and thermal degradation under sustained high-RPM operation. The full roller design eliminates friction at the pushrod interface, reducing parasitic power loss and extending component life compared to traditional cup designs. The 7/16-inch stud mount provides secure attachment to the cylinder head, ensuring consistent valve timing across engine cycles and maintaining critical valve clearances even under aggressive acceleration.

This rocker arm is ideal for SBC engines running performance camshafts and high-lift valvetrains. Installation requires proper stud installation and torque specifications per your engine builder's specifications. Each arm is sold individually, allowing builders to purchase complete sets as needed for their specific cylinder head configuration. CROWER's enduro-class design makes this component suitable for extended street use, weekend racing, or high-revving performance applications where reliability under load is non-negotiable.
