The Stealth Mach 1 Turbo is an upgraded direct replacement turbocharger for 2001-2004 Chevrolet Silverado and GMC Sierra HD trucks with the 6.6L LB7 Duramax diesel engine. This stock-appearing, drop-in IHI-style turbo is capable of supporting up to 640 RWHP while improving power, towing performance, and overall drivability.
Built with a custom-designed high-flow turbine assembly, 7075 billet compressor wheel, liquid-cooled construction, and 360-degree thrust bearing, the Stealth Mach 1 delivers improved efficiency under heavy load. The larger turbine assembly helps lower drive pressure, improve boost-to-drive pressure balance, and reduce EGTs when the truck is working hard.
