Fits 2003-2004 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins (235-305 HP engines). This kit does not fit 2004.5-2007 Cummins 325/600 engines.

Under high-boost conditions, the stock wastegate actuator's weak spring often allows the valve to blow off its seat prematurely. This premature opening bleeds off pressure, softening mid-range boost and killing torque. The Banks Power BigHead Wastegate Actuator (MPN: 24331) solves this by utilizing twice the diaphragm area and significantly higher spring pressure than the factory unit. This design keeps the wastegate seated longer to achieve higher peak boost sooner, then provides precise control to maintain that boost for crisp acceleration and superior pulling power.

• Improved Boost Response: Keeps the wastegate valve seated longer for faster boost build-up and higher peak pressure.
• Heavy-Duty Construction: Features double the diaphragm area and increased spring pressure compared to the OEM actuator.

Under high-boost conditions, factory wastegate actuators often suffer from weak spring tension, allowing the valve to blow off the seat prematurely. This exhaust backpressure leak limits midrange torque and softens boost response. The Banks Power BigHead Wastegate Actuator (MPN 24401) is engineered to solve this by providing significantly higher tension and more precise control than the OE component.

With twice the diaphragm area and spring pressure of a stock actuator, the BigHead holds the wastegate seated longer to build boost faster. Once peak boost is reached, the actuator precisely manages the valve position to maintain maximum air density for improved acceleration and heavy-duty towing performance. This unit is designed to bolt directly onto either the factory turbo housing or a Banks upgrade housing.

• Prevents premature wastegate opening under high-boost conditions
• Doubles the diaphragm area and spring pressure compared to stock
• Holds wastegate closed longer for quicker boost onset and higher peak levels
• Delivers superior midrange torque and pulling power
• Precise boost control for crisp throttle response
• Compatible with factory and Banks turbo housings
• Manufacturer Part Number: 24401

The Banks Power BigHead Wastegate Actuator Kit (MPN: 24329) is engineered to solve the common issue of wastegate blow-open under high-boost conditions. While factory actuators rely on weak springs that allow the valve to unseat prematurely, limiting mid-range torque, the BigHead replaces the entire unit with a heavy-duty design that maintains higher peak boost and improves acceleration.

By doubling the stock diaphragm area and spring pressure, this actuator keeps the wastegate valve seated longer, allowing the turbocharger to build boost faster. This results in superior pulling power and torque right from idle through the mid-range. Unlike bleed orifices or "boost foolers" that simply mask performance issues, the BigHead provides mechanical control for consistent, reliable boost management.

• Prevents wastegate blow-open for increased mid-range torque
• Doubles the diaphragm area and spring pressure compared to OE
• Achieves peak boost sooner for crisper acceleration
• Direct replacement for the stock actuator
