T AND D MACHINE 2301-160/160 SBC Shaft Rocker Arm Kit, 1.60 Ratio

The T AND D MACHINE 2301-160/160 SBC Shaft Rocker Arm Kit is a shaft-mounted valvetrain component set designed for small block Chevy applications. It features a 1.60 rocker ratio on both intake and exhaust positions, supporting consistent rocker arm movement within the engine’s valvetrain.

This kit uses a full-roller rocker arm design and aluminum construction with a natural finish. The shaft-mount configuration provides a unified mounting arrangement for the rocker arms, while the roller design is intended for smooth contact at the valve and pushrod interfaces.

The 2301-160/160 kit is specified for AFR 227 and AFR 235 applications. Its application-focused design makes it suitable for engine builds requiring a 1.60/1.60 rocker arm ratio and shaft-mounted rocker arm hardware for a small block Chevy platform.

Verify engine, cylinder head, and valvetrain requirements before installation to confirm that the rocker ratio and AFR 227/235 application specifications match your build.
