Garrett Powermax GT3794VA Stage 1 turbocharger for 04.5-10 Duramax engine codes LLY/LBZ/LMM. This turbo features a larger compressor wheel compared to stock. It utilizes nine moveable vanes which increase turbine effciency and improves the vehicles engine performance. The turbo can support up to 500HP.
