A variable compound rocker system for varying the lift of intake valves of an internal combustion engine is provided. The system comprises a rocker shaft with eccentric rings non-rotatably attached thereto. Furthermore, the system includes primary rockers non-rotatably attached to the eccentric rings. The primary rockers have engaging surfaces for engaging rollers attached to secondary rockers. The rollers enable the primary rockers to actuate the secondary rockers, thus actuating the intake valves. The system further includes an actuator assembly adapted to incrementally rotate the rocker shaft, and thus the primary rockers. This incremental rotation of primary rockers changes their attitude causing the lift of the intake valves to vary, thus varying the engine performance characteristics.
