T&D Machine 2309-170/170 Shaft Rocker Arm System for GM LS with AFR LS3 Heads

The T&D Machine 2309-170/170 is a precision-engineered shaft rocker arm system designed specifically for GM LS engines equipped with AFR LS3 cylinder heads. This high-performance rocker system provides superior valvetrain stability and geometry optimization compared to factory stud-mounted rockers.

Key Features:

• Shaft-mounted design eliminates rocker arm deflection and provides consistent geometry throughout the valve lift cycle
• CNC-machined from high-grade steel or aluminum alloy for exceptional strength and durability
• Roller bearing or bushing design reduces friction for improved valvetrain efficiency and horsepower gains
• Engineered for optimal geometry with AFR LS3 cylinder heads to maximize valve lift and flow
• 1.70:1 ratio on both intake and exhaust rockers for increased valve lift
• Includes rocker arms, shafts, stands, and all necessary mounting hardware

T&D Machine rocker systems are trusted by professional engine builders and racers for their precision manufacturing and performance reliability. This system is ideal for high-performance street engines, drag racing applications, and road racing builds where valvetrain stability at high RPM is critical.
