2004.5-2010 Duramax (LLY, LBZ, LMM)


The popular Garrett PowerMax GT4094VA is a direct, bolt-in replacement for the stock turbo on your ’04.5-’10 Duramax. Despite having a larger-than-stock 67.7mm compressor wheel, spool up is hardly affected thanks to its Advanced Variable Nozzle Turbine (AVNTTM) design. The turbine housing utilizes 9 movable vanes to vastly increase turbine efficiency from launch through high rpm. This is a great variable geometry upgrade for LLY and newer trucks. It flows approximately 1,200 cfm and supports 650 hp.
