SBC H/E Alum. R/A's - 1.6 Ratio 7/16 Stud

The SBC H/E Alum. R/A's - 1.6 Ratio 7/16 Stud from COMP CAMS is a precision-engineered rocker arm assembly designed for small-block Chevrolet (SBC) engine builds where mechanical advantage and reliable valve actuation are essential. These aluminum roller rockers cater to serious enthusiasts and professional engine builders who seek consistency across high-RPM applications, street performance builds, and race-oriented powerplants.

The 1.6 ratio geometry multiplies camshaft lift by 1.6 times, making them ideal for maximizing valve opening without requiring extreme camshaft duration. Constructed from lightweight aluminum, these roller rocker arms reduce parasitic losses compared to cast iron alternatives while maintaining structural integrity under sustained load. The 7/16-inch stud attachment provides a secure, industry-standard connection point compatible with standard SBC cylinder head configurations and aftermarket stud girdles.

These rocker arms fit SBC platforms including 262, 283, and others, making them a versatile choice for various builds. Roller bearing construction minimizes friction at the pushrod and valve stem interfaces, extending component life and improving efficiency across the entire RPM band. When paired with aggressive valve spring packages and high-lift camshafts, the 1.6 multiplication ratio delivers measurable performance gains, particularly for builds targeting 5,500+ RPM operation.
