2004.5-2010	Chevrolet/GMC HD	6.6L Duramax

The VVT Stealth Mach 1 Hybrid Turbo is a specialized stock-appearing direct replacement turbocharger for 2004.5-2010 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks with the 6.6L LLY, LBZ, or LMM Duramax diesel engine. Designed for sled pulling and compound turbo applications, this turbo combines Mach 2-style exhaust-side upgrades with a smaller 63mm Air Grabber compressor wheel.

This hybrid setup is optimized for top-end performance, compound turbo efficiency, and competition applications limited to a 64mm compressor wheel. With HFV High Flow Vane technology, an upgraded turbine wheel, ported exhaust housing, and heavy-duty bearing upgrades, it improves exhaust-side flow and helps manage EGTs under high-load conditions.
