SBC Roller Rocker Arms - 1.6 Ratio 7/16 Stud

The SBC Roller Rocker Arms – 1.6 Ratio 7/16 Stud by PRW Industries are designed for Small Block Chevy enthusiasts looking to enhance performance and reliability in high-RPM applications. These roller rocker arms provide precision valve train geometry and reduced friction losses, making them ideal for street performance engines and weekend racers alike.

Engineered to maximize head flow without over-stressing pushrods or valve springs, the 1.6:1 lift ratio enhances valve lift while maintaining precise geometry throughout the valve event. The 7/16-inch stud size ensures secure fastening to the cylinder head, minimizing deflection under peak cylinder pressure and dynamic loading. These components are typically made from high-strength aluminum, providing durability and performance.

Ideal for builders seeking improved throttle response and fuel efficiency, these roller rockers are a significant upgrade over traditional stamped-steel designs. Whether refreshing a tired hydraulic cam setup or building a new performance engine, these rocker arms deliver consistent valve timing and reduced parasitic losses, making them a valuable addition to any Small Block Chevy project.
