2004.5-2010 Duramax Stealth Mach 2 Turbocharger (CPS200340)

Fits

The Stealth Mach 2 Turbo is an upgraded stock-appearing VVT turbocharger for 2004.5-2010 Chevrolet Silverado and GMC Sierra HD trucks with the 6.6L Duramax diesel engine. Designed for LLY, LBZ, and LMM applications, this turbo is built to spool quickly, feel responsive, and move significantly more air than the factory turbocharger.

With HFV High Flow Vane technology, a custom billet compressor wheel, oversized custom turbine wheel, and 360-degree thrust bearing, the Stealth Mach 2 is designed for strong street manners, towing performance, and competition-level power potential while maintaining drop-in fitment.
