Banks Big Head Wastegate Actuator for 2001–2004 LB7 Duramax Turbo Systems

Description

Fits: 2001 thru 2004 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7 Duramax Diesel

When turbo exhaust back pressure 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.

Features:

• Quick, Controlled Boost
• Produces more torque right from idle
• Keeps the valve seated longer, achieving higher peak boost, sooner
• Crisp Acceleration and more mid-range pulling power
