Description

The Garrett 773540-5001S PowerMax GT3794VA Stage 1 Turbocharger is a must have for any 04.5-10 GM 6.6L Duramax LLY/LBZ/LMM Duramax owner thats 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. The GT3794VA 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
GT3794VA 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 GT3794VA turbocharger will increase your maximum power range while supporting up to 500HP with no sacrifice to drivability.

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

Note: Gaskets not included.

Features:
  • Drop-In Replacement
  • Supports Up To 500HP
  • Retains Factory Electronics 
  • 1 Year Warranty



Note from Garrett regarding shaft play:

When the Powermax turbo is new, or has not operated for a long period of time allowing most of the oil to drain out, the rotating assembly will move more in the radial direction because there is no oil in the center housing. This condition is normal. As long as the shaft wheel spins freely and the wheels don't contact their respective housings, the assembly will function properly.

Great turbo

| March 1st, 2019
I installed this myself on my 07 LBZ. Installation was straightforward and turbo went in nicely. Turbo was received very well packed and there is no way it could have been damaged during shipment. Manufacture and XDP did an excellent job getting the product to me safely. The only other thing I will add is that the turbo does not come with the oil drain pipe seals (upper & lower). It also does not come with the oil/coolant seals either. I had to go to two different Chevy dealerships to get all 5 seals. Great turbo and I will be a returning customer to XDP and would buy this product again. Invoice number 1506699
