Supports up to 640RWHP! The BEST drop-in style, LB7 turbo on the market today!


The LB7 Stealth 64 Turbo is a direct drop-in, bolt-on stock appearing replacement with features you won’t find anywhere else. Your 2001, 2002, 2003, or 2004 LB7 6.6L Duramax will have improved power, perform better while towing and experience overall increased performance.  This is capable through the use of a custom-designed high-flow turbine assembly and 7075 billet compressor wheel.  We do all this in a liquid-cooled package protected by 360-degree thrust bearings.


The larger turbine assembly allows for lower drive pressure, creating a better balance between boost and drive (exhaust backpressure). This improved balance under heavy load means more efficiency and power at a given boost number, resulting in lower EGTs under heavy load. Overall peak power is also improved, the LB7 Stealth 64  pushes the envelope to 640HP. You’re not going to find all of these features anywhere else in the aftermarket in a truly stock-appearing, bolt-in IHI-style turbocharger.
