2004.5-2010 Duramax XR3 Series Turbocharger 71MM/67MM (773540-0001-XR3)

Industrial Injection XR3 Series drop-in turbocharger for the 2004.5-2010 6.6L Duramax (LLY, LBZ and LMM). A direct replacement for the factory variable-vane turbo that swaps the wheels and vanes for a larger, more efficient performance setup while keeping the OE form factor.

The XR3 pairs a 71mm Billet Blade Technology compressor wheel with a slim-nose profile and a 67mm high-flow turbine wheel. Nine movable vanes improve turbine response and efficiency across the rpm range — from idle launch through peak torque — for lower EGTs and stronger top-end pull.
