LS3 Rocker Arm Kit 1.7 Ratio w/8 Offset

The LS3 Rocker Arm Kit 1.7 Ratio w/8 Offset from Straub Technologies Inc. is specifically engineered for LS engine builders and performance enthusiasts looking to enhance valvetrain geometry and lift characteristics. This precision-machined rocker arm assembly is ideal for high-rpm applications where stock geometry may limit horsepower potential.

The 1.7 ratio indicates that for every unit of lift from the camshaft, the valve will lift 1.7 units, providing a mechanical advantage that optimizes cam profile utilization across the power band. The 8-degree offset enhances valve actuation geometry, improving pushrod angle and reducing side loading on valve stems, which decreases wear and enhances sealing consistency under load. Manufactured to exacting tolerances with premium materials, these components ensure durability in high-horsepower and high-rpm environments.

This rocker arm kit is particularly beneficial for LS-platform engine swaps and crate motor builds, making it an excellent choice for performance and race applications. Its compact assembly, weighing 7.05 lbs, integrates seamlessly into stock and modified LS3 engine bays without requiring extensive fitment modifications.
