LS3 Shaft Rocker Kit - Unassembled

The LS3 Shaft Rocker Kit – Unassembled from Brian Tooley Racing is designed for serious LS engine builders and enthusiasts who demand maximum valve train control and durability. This unassembled kit allows experienced mechanics and custom builders to inspect, prepare, and install each component to their exact specifications, ensuring proper fitment and longevity in high-performance applications.

Brian Tooley Racing's LS3 shaft rocker design replaces factory stamped-steel rocker arms with precision-engineered components that provide superior mechanical advantage, reduced deflection, and enhanced valve lift consistency across the entire RPM range. Shaft rockers offer tighter tolerances and lower friction compared to stud-mounted alternatives, translating to improved throttle response and valve actuation reliability under aggressive cam profiles and high lift scenarios.

This unassembled kit gives builders the flexibility to select compatible pushrods, rocker arm studs, and supporting hardware tailored to their specific engine configuration. LS engine rebuilds and race builds benefit most from this kit, particularly when pairing aggressive hydraulic or solid-roller camshafts for optimal performance.
