The Garrett 73542-5001S PowerMax GT4094VA Stage 2 Turbocharger is a must have for any 04.5-09 GM 6.6L Duramax LLY/LBZ/LMM Duramax owner that’s looking to get more out of their truck. Featuring the Garrett patented Advanced Variable Nozzle Turbine (AVNT) design for increased compressor flow and boost response. This turbocharger features a larger compressor trim (52), plus larger GT40 turbine wheel and vanes over the Stage 1 model. The GT4094VA also utilizes nine movable vanes which significantly increase turbine efficiency and improves engine performance from idle launch through peak torque. 

Designed as a “drop-in upgrade”, the GT4094VA retains use of factory components such as engine electronics, mounting pedestal and requires no additional modifications to your factory exhaust system. Utilizing a larger compressor wheel the GT4094VA turbocharger will increase your maximum power range while supporting up to 575HP with no sacrifice to drivability.

While this turbocharger is suitable as a replacement for factory equipment, it’s recommended that additional fueling upgrades such as aftermarket/custom tuning are installed or already in use. Includes turbocharger, adapter cable and installation instructions. 


  • Retains Factory Electronics
