Garrett PowerMax Stage 1 AVNT Turbo Kit for 2004.5-2009 Chevy/GMC 6.6L Duramax

GRT773540-5001S

Your 2004.5-2009 Duramax is due for a turbo, so why not make it a real upgrade? The Garrett PowerMax Stage 1 kit fits Chevy and GMC 2500 and 3500 trucks and works as a performance upgrade or a straight replacement for the factory unit.

It uses Garrett's patented AVNT (Advanced Variable Nozzle Turbine) design with nine movable vanes for more compressor and turbine flow. Garrett says that boosts turbine efficiency and engine performance from idle launch through peak torque. GT Series wheels deliver lower back pressure and reduce intake and exhaust gas temperatures. Patented integral electro-hydraulic actuation with a proportional solenoid gives infinitely variable vane control.

  • Part number: 773540-5001S (Stage 1)
  • Rated power: 590 HP, Garrett estimate (results depend on your modifications and tuning)
  • Turbine: AVNT variable nozzle, nine movable vanes
  • Actuation: integral electro-hydraulic with proportional solenoid
