LS Shaft Rocker Arm Kit 1.7 Ratio LS1/LS2/LS6

The LS Shaft Rocker Arm Kit 1.7 Ratio LS1/LS2/LS6 by COMP CAMS is purpose-built for LS engine builders and performance enthusiasts seeking to optimize valve actuation and increase engine responsiveness. This kit represents a critical upgrade for anyone running an LS platform engine—whether you're building a street machine, weekend track car, or high-performance crate engine swap. Shaft rocker arms deliver superior stability and precision compared to stud-mounted alternatives, especially under aggressive valve spring pressures and high-RPM operation.

The 1.7 rocker arm ratio fundamentally changes how your engine breathes by increasing valve lift and duration relative to camshaft lobe movement, translating cam profile into more aggressive valve timing without requiring a larger cam. COMP CAMS engineered these shaft rocker arms with precision-ground bore tolerances and hardened steel construction to handle the side loads and stress cycles inherent to high-lift, high-duration cam profiles. The shaft-based design distributes oil pressure evenly across all rockers, ensuring consistent valve control and reducing deflection that plagues traditional rocker geometries—critical when you're pushing 7,000+ RPM or running solid roller cams with aggressive spring rates.

This kit is specifically engineered for LS1, LS2, and LS6 engines commonly found in Corvettes, Camaros, and LS swap platforms. Installation requires proper valve lash setup and pushrod length verification to avoid binding or excessive clearance—a critical step that separates successful builds from costly mistakes. Whether you're maximizing flow on a naturally aspirated stroker or supporting a supercharged application, the 1.7 ratio rocker arm delivers the mechanical advantage needed to unlock cam potential while maintaining reliability across the full RPM band.
