The OEM technology found in every Garrett turbocharger is now available as complete drop-in performance turbo kits for the 2004.5-2010 GM/Duramax. The unequaled durability, quality and reliability will help you take your truck's power to the next level. The PowerMax line offers patented Garrett dual ball bearing cartridges for unbeatable response and efficiency as well as the advanced GT-series wheel aerodynamic designs that ensure top performance, lower back pressure and reduced intake and exhaust gas temperatures.
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.
