Transform your 2011–2016 LML Duramax with the Fleece Performance 63mm FMW Cheetah Turbocharger (part # FPE-LML-VNT-63-FMW-N). This is a true bolt-on, stock-appearing performance upgrade that uses the factory VNT housings and connections while delivering significantly better spool, throttle response, and top-end power.

Built with genuine Garrett components and Fleece’s exclusive 63mm Forged Milled Wheel (FMW) compressor, this Cheetah turbo gives you the best of both worlds: quick spool-up and sharp low-RPM response like a smaller turbo, plus strong top-end flow and a broader torque curve. Rated for up to 650 RWHP, it’s the ideal dual-purpose turbo for trucks that tow during the week and perform on the weekends.

The high-flow Cheetah turbine wheel, upgraded shaft bearings, and 360° thrust bearing provide excellent durability under higher boost levels (safely supports 40–45 PSI) while keeping the exterior 100% stock-appearing — no custom piping or fabrication required.
