SBF Shaft Rocker Kit w/TFS3 High Port Heads

The SBF Shaft Rocker Kit with TFS3 High Port Heads from T and D Machine is engineered for serious small-block Ford builders who demand precision valve actuation and maximum airflow efficiency. This complete rocker assembly transforms cylinder head performance by optimizing the mechanical link between camshaft and valve train, making it essential for high-rpm applications, competition engines, and stroker builds. Whether you're building a daily-driver powerhouse or track-focused race engine, this kit addresses the critical need for reliable, low-friction rocker geometry at elevated engine speeds.

The shaft rocker design uses a solid steel shaft mounting system that maintains precise valve geometry under load, eliminating the flex and compliance issues found in bolt-on stud-mount rockers. T and D Machine engineers the 1.6:1 ratio into both intake and exhaust rockers, delivering a balanced valve lift curve that complements high-port TFS3 cylinder head flow characteristics without sacrificing valve lift margin or durability. The hardened rocker arms feature optimized wear surfaces and hardened pushrods for extended service life, while the shaft mounting architecture distributes loads evenly across all valve locations—critical for preventing rocker arm wear, pushrod flex, and valvetrain harmonics that degrade power at peak RPM.

Engine builders targeting 6000+ RPM small-block Ford applications benefit most from this rocker kit, particularly those pairing Trick Flow's high-port heads with aggressive hydraulic or solid-roller cam profiles. Installation requires proper pushrod length selection and rocker arm geometry verification to ensure correct valve lash and zero-lash hydraulic lifter preload. Compatibility spans most small-block Ford engine families (221, 255, 289, 302, 351W) when used with appropriate head mounting plates and valve cover clearance verification for your specific intake manifold and accessory configuration.
