1 - Low-Medium Speed Intake Rocker Arms
2 - High Speed Intake Rocker Arm
3 - Synchronizing Pistons
4 - High Speed Cam Lobe
5 - Camshaft
6 - Intake Valves
When engine speed exceeds 4,400 RPM engine oil is allowed to flow unobstructed to the rocker arms. This flow of oil into the rocker arm oil passages
creates an increase in oil pressure. The increase in oil pressure moves the synchronizing pistons (3) further into their bores, compressing the piston
spring. As the spring is compressed, the shifted pistons lock all three rocker arms together (1 and 2). When locked together, the low-medium speed
rocker arms (1) follow the movement of the high speed rocker arm (2). Because the high speed rocker arm (2) is following the high speed cam lobe (4),
the intake valves (6) open with more lift.
