Pro Shaft Rocker Kit SBC 1.60/1.60 AFR 227/235

The JESEL Pro Shaft Rocker Kit SBC 1.60/1.60 AFR 227/235 is a high-performance valve train component designed for serious small-block Chevrolet builders seeking enhanced reliability and performance at high RPM. This complete rocker arm system replaces factory stamped-steel rockers, providing superior valve actuation geometry and durability, especially when paired with AFR cylinder heads featuring 227cc or 235cc intake port volumes.

The 1.60:1 rocker arm ratio increases valve lift relative to camshaft lobe lift, effectively enhancing the lift and duration characteristics of your camshaft without the need for a custom grind. JESEL's Pro Shaft design incorporates a dedicated shaft support system that minimizes deflection under load, ensuring precise valve timing and reducing the risk of bind-up issues commonly associated with factory rocker studs.

This rocker kit is ideal for enthusiasts building naturally aspirated small-block combinations with aggressive cam profiles, where factory rockers may fall short. Its compatibility with AFR 227/235 heads ensures optimized valve seating angles and port alignment, making it a crucial upgrade for both street performance and competition applications.
