2004.5-2010 Duramax Stealth Mach 1 Turbocharger (CPS200281)

The Stealth Mach 1 64 VVT Turbo is an upgraded direct replacement turbocharger for 2004.5-2010 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks with the 6.6L Duramax diesel engine. Designed for LLY, LBZ, and LMM applications, this turbo offers quick spool-up, strong EGT control, turbine braking capability, and excellent towing performance.

The stock LLY, LBZ, and LMM turbocharger can run out of airflow around higher power levels and may struggle with EGT control during extended pulls. The Stealth Mach 1 64 VVT extends the useful power curve with a specially designed billet compressor wheel matched to a higher-flowing turbine assembly, delivering a strong balance of response, drivability, and peak power.
