Banks Power 01-04 Chevy 6.6L Big Head Actuator Kit

Under high-boost conditions, the stock actuator's weak spring allows the wastegate to blow open, limiting midrange torque. Bleed orifices (also known as "boost foolers") just make it worse. Only Banks solves this problem by replacing the boost actuator. BigHead holds the wastegate closed for quicker boost, then controls the opening to maintain peak boost for superior acceleration and mid-range pulling power. BigHead Wastegate Actuator Kit for use with 2001-2004 Chevy 6.6L. Power Now! When turbo exhaust backpressure increases, the stock actuator prematurely blows off the seat, softening boost in the midrange and killing torque. With twice the diaphragm area and spring pressure of the stock wastegate, Banks BigHead Wastegate Actuator keeps the valve seated longer and achieves a higher peak boost, sooner. At peak, BigHead opens the wastegate and holds its position, for precise boost control that gives you crisp acceleration and more mid-range pulling power. Key Features: Quick, Controlled Boost. Produces massive torque right from idle. Doubles stock's diaphragm area and spring pressure. Keeps the valve seated longer achieving higher peak boost, sooner. Crisp acceleration and more mid-range pulling power. Fits LB7 engine BigHead Actuator, BigHead Wastegate Actuator Kit for 2001-2004 Chevy/GMC 2500/3500 6.6L Duramax For Replacement Parts Only

• For higher peak boost, sooner
• More Mid Range Muscle

The Banks Power BigHead Wastegate Actuator Kit is designed specifically for 2001-2004 Chevy and GMC 6.6L Duramax engines, providing superior boost control and enhanced mid-range torque. Under high-boost conditions, the stock actuator's weak spring allows the wastegate to open prematurely, which softens boost levels and reduces overall torque output. This kit replaces the stock actuator with a high-performance unit featuring twice the diaphragm area and spring pressure, ensuring the wastegate stays seated longer and achieves higher peak boost levels sooner. As a result, you experience crisp acceleration and increased pulling power in the mid-range, making it ideal for towing, performance driving, and maximizing your engine's potential. The BigHead actuator maintains precise control by holding the wastegate open at peak boost, preventing boost creep and providing consistent performance across different driving conditions. Installation is straightforward, and the kit is compatible with several GMC Sierra 3500 models from 2001 through 2003, offering a reliable upgrade that enhances turbo response and overall engine efficiency. Engineered for durability, the Banks BigHead Wastegate Actuator kit doubles the effectiveness of the stock unit, delivering increased torque and improved throttle response, especially during high-boost scenarios. Designed for replacement purposes, it ensures your engine maintains optimal boost levels, helping you get the most out of your Duramax diesel. Proper boost management provided by this kit translates into better acceleration, more mid-range muscle, and a more responsive driving experience. Whether you're towing heavy loads or seeking enhanced performance, the Banks Power BigHead Wastegate Actuator Kit is a proven upgrade for your diesel truck.
