The SBF Shaft Rocker Arm Kit – 1.6/1.6 Ratio by T and D Machine is a precision-engineered component designed for small-block Ford engine builders and performance enthusiasts who demand reliability and consistency in high-RPM applications. This kit is ideal for builders working with small-block Ford platforms including 289, 302, 347, 351W, and similar displacements where OEM rocker geometry limits performance potential.
The rocker arm system addresses the critical need for proper valve actuation geometry and durability under sustained load. SBF shaft rocker arms offer superior stability compared to stud-mounted alternatives, utilizing a full-length shaft that distributes loads evenly across all eight rockers. This architecture maintains precise valve opening and closing angles, reduces parasitic power loss, and extends component lifespan—critical advantages when operating at elevated RPM or boost levels.
Installation requires compatible cylinder heads, making it essential for any serious Ford performance program. The 1.6/1.6 ratio designation indicates equal mechanical advantage across both intake and exhaust valves, providing balanced lift and duration characteristics that work in harmony with your cam profile and cylinder head porting. This kit is perfect for those looking to enhance their engine's performance and reliability.
