Banks Power 24396 BigHead Wastegate Actuator

Is your wastegate blowing open prematurely, causing higher Exhaust Gas Temperatures (EGTs) and drivability issues? The Banks Power 24396 BigHead Wastegate Actuator is a direct-fit replacement for the tired wastegate in your 2001-2004 GM 6.6L Duramax LB7. This high-performance wastegate will keep the valve closed longer to restore lost performance. Under high-boost conditions, the factory actuator's weak spring allows the wastegate to blow open, limiting midrange torque. This wastegate keeps the wastegate closed for faster boost, then controls the opening to maintain peak boost for greater acceleration and mid-range pulling power. 

The Banks Power BigHead Wastegate Actuator has twice the diaphragm area and spring pressure of the stock unit, keeping the valve seated longer and achieving a higher peak boost. At peak boost, this actuator opens the wastegate and holds its position, for precise boost control that gives you crisp acceleration and more mid-range pulling power.
