The LML Stealth Mach 1 Hybrid Turbo is a specialized stock-appearing direct replacement turbocharger for 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks with the 6.6L LML Duramax diesel engine. Designed for turbo class limited sled pullers and compound turbo applications, this turbo combines the internals of the Mach 2 platform with a smaller 63mm Air Grabber compressor wheel.
This hybrid configuration is optimized for top-end performance, compound turbo efficiency, and competition setups 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 helps improve exhaust-side flow and manage EGTs under high-load conditions.
