Our Engines are the next step in the evolution of diesel turbo vehicles. Duramax Engines are built for extreme terrains and field-proven with enhanced engine performance. The Duramax Power Train conversion begins by removing the OEM engine and replacing the OEM setup with a Duramax 6.6L Engine (LMM or LBZ series). The turbo setup on these engines utilize a Garrett VVT (variable vane turbocharger) and air-to-air intercooler allowing instant boost with minimal turbo lag throughout the entire power band. Each engine is equipped with our Predator Raptorq ECM upgrade, delivering apx. 465HP and 1100 foot lbs of torque. These engines are available in LBZ or LMM configurations.
