The GMC 2500 Wastegate Actuator by Banks Power, also known as the Big Head, is a high-performance upgrade specifically engineered for Chevy/GMC 2500/3500 models with the 6.6L Duramax engine from 2001 to 2004. Designed to tackle the limitations of stock actuator systems, the Big Head delivers better torque and acceleration by improving wastegate control under high-boost conditions.

The Big Head Wastegate Actuator addresses the common issue of the stock actuator's weak spring, which can cause the wastegate to blow open when under high boost, limiting your vehicle's midrange torque and performance. Banks Power has developed this wastegate actuator kit to ensure the valve remains closed longer, increasing both the diaphragm area and spring pressure compared to the original equipment. This results in a higher peak boost that is achieved sooner, offering superior acceleration and mid-range pulling power. With improved boost control, your Duramax-powered vehicle can achieve crisper acceleration and greater pulling power for an enhanced driving experience.

• Quick, Controlled Boost: Produces significant torque right from idle.
• Doubles the stock diaphragm area and spring pressure.
• Enhances acceleration and mid-range pulling power.
• Precisely controls boost levels for better performance under load.
• Specifically fits LB7 engine models from 2001-2004.
