Big Block Chevy engines demand the best in valvetrain stability, and Harland Sharp Original Series 1.8 ratio rocker arms deliver exactly that. Designed to handle the increased torque and stress of a high-performance BBC build, these full roller rockers provide the leverage needed to maximize airflow and engine output. With a 1.8 ratio, you gain significant valve lift, allowing your engine to breathe better and produce more power across the powerband.
These rocker arms feature a robust 7/16 stud mount design, ensuring that your valvetrain remains stable under high-RPM conditions. The premium aluminum construction is both lightweight and incredibly strong, while the orange anodized finish provides superior corrosion resistance and a professional look. By utilizing a full roller tip, these rockers minimize friction and heat, extending the life of your valve stems and guides significantly.
Whether you are drag racing or building a high-horsepower street machine, these rockers are the foundation for a reliable and powerful valvetrain. Upgrade your Big Block Chevy today with high-performance components from GGCRACING.
