Ready to take your LML Duramax to the next level? The Stealth Mach 1 (64) Turbo is the ultimate bolt-in upgrade for serious performance, fast spool-up, and max towing capability.

Whether you’re looking for more horsepower, better throttle response, or just lower EGTs, this turbo delivers in every category, all without the hassle of a core charge. Designed to support up to 650 RWHP with supporting mods (or 600 RWHP with emissions intact and tuning), this turbo is built for the real world, daily driving, towing, and everything in between. With an 11-blade extended tip billet compressor wheel and a custom oversized 9-blade turbine, the Stealth Mach 1 64 offers better flow, lower EGTs, and an aggressive turbo whistle that makes your truck sound as good as it performs. This isn't just another turbo swap, it's a game changing upgrade designed for use with tuning to optimize power, airflow, and efficiency. The 64mm Air Grabber Compressor Wheel maximizes airflow, while the Beast Wheel Turbine Wheel is 8% larger than stock for better exhaust flow and zero surge, even under heavy loads. With machine ported up-pipe inlets and a ported downpipe opening, this turbo moves air like no stock turbo can. It utilizes heavy duty journal bearings, a 360° thrust bearing, aerospace grade materials, and all brand new parts, to ensure long term reliability. You can install it and hit the road with confidence.

If you daily drive your truck, tow heavy loads, or just want more power with excellent street manners, this turbo is built for you. No piping kits, no complicated installs, just a direct bolt in replacement for your factory turbo on 2011-2016 Duramax LML trucks. With no core charge, this turbo upgrade is the perfect balance of power, reliability, and designed for real world performance.
