High-Performance 1.65 Ratio Rocker Kit

Take your Small Block Ford to the next level with the T&D Machine 1.65 ratio shaft rocker kit, tailored for AFR 205 and 220 Big Valve cylinder heads. This kit provides a slight increase in valve lift over standard 1.6 rockers, helping you extract more power from your engine's airflow potential. The shaft-mount design is the gold standard for high-performance valvetrains, offering unmatched stability and durability.

Why Upgrade Your Valvetrain?

• 1.65 Ratio: Offers a performance boost for optimized cam profiles.
• AFR 205/220 Fitment: Precision-engineered for big valve head geometry.
• Shaft-Mount Rigidity: Eliminates rocker stud flex and improves valve timing accuracy.
• Full Roller Design: Minimizes friction for increased power and component longevity.
• Durable Construction: High-strength aluminum designed for the rigors of racing.

The T&D Machine shaft rocker system is designed to handle the increased spring pressures and aggressive cam profiles found in high-output SBF builds. By maintaining perfect rocker geometry, this kit ensures that your valves open and close exactly when they should, preventing valve float and maximizing volumetric efficiency. The natural finish aluminum rockers are built to last, providing a reliable foundation for your high-performance engine. If you are running AFR 205 or 220 heads, don't compromise on your valvetrain—choose the precision of T&D Machine. Shop for this and other top-tier automotive parts at GGCRACING.
