Pontiac Rocker Arms - 1.5 Ratio 7/16 Stud

The Pontiac Rocker Arms - 1.5 Ratio 7/16 Stud from SHARP ROCKERS is an essential upgrade for Pontiac engine builders and performance enthusiasts looking to enhance valve train geometry. These rocker arms are specifically designed for classic Pontiac engines that require a 1.5:1 mechanical advantage ratio, making them ideal for cam swaps and high-RPM applications.

Engineered with precision-machined construction and hardened steel components, these rocker arms are built to withstand the stresses of sustained valve train operation at elevated RPM. The 1.5:1 ratio effectively multiplies camshaft lift, meaning a 0.500-inch cam lobe produces 0.750 inches of valve lift, which is crucial for optimizing airflow through modified cylinder heads.

These rocker arms are compatible with Pontiac 350, 389, 400, and 455 engines, particularly those utilizing solid-lifter cams. By ensuring secure mounting with a 7/16-inch stud configuration, they help maintain proper preload and reduce valve train chatter, making them a reliable choice for performance builds.
