Fleece 63 mm FMW Duramax Cheetah Turbocharger (STREET) | 2004.5‑2010 Silverado/Sierra 2500‑3500

Give your LBZ/LMM Duramax the best of both worlds with the 63 mm FMW Cheetah STREET turbo. Built around genuine Garrett VNT hardware, it drops into the stock housings but swaps in Fleece’s forged‑milled‑wheel (FMW) 63 mm billet compressor and a 66 mm high‑flow turbine for rapid spool‑up, crisp throttle response, and reliable airflow up to 625 RWHP. Perfect for work‑week towing and weekend sled‑pulling-all while keeping factory drivability and emissions equipment intact.

Key Benefits

• 100 % stock‑appearing drop‑in-no extra piping, sensors, or wiring required.
• FMW 63 mm billet compressor-lighter, stronger, faster to spool than cast or standard billet wheels.
• 66 mm high‑flow turbine & upgraded 360‑degree thrust bearing for lower drive pressure and cooler EGTs.
• Variable Nozzle Technology (VNT)-acts small off‑idle and big on the top end; great for towing.
• Safely handles 40‑45 psi boost with supporting tuning and exhaust.
• Rated to ≈ 625 RWHP*; ideal for dual‑purpose street/strip trucks.

What’s Included

• Cheetah 63 mm VNT turbo assembly with new pre‑calibrated actuator
• Exhaust flange gasket, oil‑feed washers, hardware, and install guide
• Core return instructions (return your 2004.5‑2010 turbo for credit)
