Pro Shaft Rocker Kit SBF TFS High Port 1.60/1.60

The Pro Shaft Rocker Kit SBF TFS High Port 1.60/1.60 is a precision-engineered valve train component designed for serious small-block Ford builders seeking maximum performance and reliability. This rocker arm assembly from JESEL is ideal for high-revving applications where stock rockers may fail under sustained load, particularly for engines pushing beyond 7,000 RPM.

The pro-shaft design features a common hardened shaft running through individual rocker arms, which helps to eliminate deflection and binding issues commonly found in shaft-on-tube or pedestal systems. The 1.60/1.60 ratio indicates both intake and exhaust rocker arms at a 1.60:1 mechanical advantage, optimizing valve lift and duration for TFS high-port cylinder heads while maintaining stable valve events across the RPM range.

This kit is essential for builders combining TFS high-port heads with performance camshafts and is particularly beneficial for those focused on street performance or competition-ready small-block engines. High-strength materials and precision manufacturing ensure minimal wear and superior durability compared to stamped-steel alternatives.
