Banks Big Head Wastegate Actuator for 01-04 CHEVY DURAMAX 6.6L Diesel LB7
Part # 24396
Power Now! Keep your wastegate from blowing open — when turbo exhaust back-pressure increases, the stock actuator prematurely blows off its seat, softening boost in the midrange and killing torque. With a diaphragm twice the size of the stock wastegate & double the spring pressure of the stock, the Banks Big Head wastegate actuator for the 2001-2004 GMC/Chevy 2500HD/3500HD 6.6L Silverado/Sierra Duramax LB7 is a simple way to achieve higher peak boost and increase mid-range pulling power.
- Doubles the stock’s diaphragm area & spring pressure
- Produces massive torque right from idle
- Achieves higher peak boost sooner
- More mid-range muscle
- Backed by a 2-year warranty
- NOTE: Designed to work with the stock turbo only.
Banks Big Head produces massive torque right from idle, achieves a higher peak boost — sooner — and maintains more boost throughout the powerband by eliminating premature wastegate blow-open. With higher overall peak boost levels, quicker spool-up and increased torque. The Banks Big Head is the perfect addition to any performance module, air intake or exhaust system.
