Pro Shaft Rocker Kit SBC 23-Deg 1.60/1.50

The JESEL Pro Shaft Rocker Kit SBC 23-Deg 1.60/1.50 is a complete shaft rocker assembly designed for serious small-block Chevy builders who prioritize precision valve actuation and high-RPM reliability. This kit is ideal for performance enthusiasts and professional engine builders working on race applications, street performance builds, and competition engines where valve train stability is crucial for maximizing power output and durability.

JESEL's shaft rocker design features a solid roller fulcrum that eliminates rocker wear and deflection, ensuring precise geometry under extreme valve spring pressures and high-frequency cycling. The 23-degree angle geometry, along with the 1.60 intake and 1.50 exhaust ratio arms, optimizes valve lift multiplication while reducing parasitic losses and side loading on pushrods. Constructed from precision-machined steel with hardened roller tips, this rocker kit is built to withstand high-lift cam applications.

This rocker kit is particularly beneficial for SBC builders who are pushing beyond 6500 RPM or utilizing aggressive camshaft profiles that require superior valve train control and minimal deflection. The 1.60/1.50 ratio configuration strikes a balance between intake and exhaust efficiency, making it versatile for both street and strip applications.
