With lightning-quick spool-up and a responsive throttle feel, it drives like stock in traffic but comes alive under load. Rated to support up to 625 rear-wheel horsepower, it gives you headroom for tuning without sacrificing low-end torque. Best of all, you don’t have to deal with complicated installs or custom parts, just drop it in and go. Whether you're after better pulling power or just want your truck to feel stronger across the board, this turbo delivers without compromise.

Built With Proven Garrett Components And FMW Technology

The Fleece Performance VNT63 Street Cheetah Turbo is engineered with a blend of OEM reliability and high-performance hardware. At its core is a 63mm forged milled compressor wheel paired with a high-flow 66mm turbine wheel, both designed to move more air without increasing lag. The forged milled wheel provides better durability than standard billet, offering faster spool and improved throttle response. This turbo is built using genuine Garrett parts and includes a 360-degree thrust bearing upgrade for long-term reliability under elevated boost pressures. Thanks to variable nozzle technology, the turbo mimics the responsiveness of a smaller unit during spool-up, then opens up on the top end for stronger high-RPM performance. It’s designed to handle 40 to 45 PSI of boost while maintaining compatibility with factory electronics, emissions systems, and downpipe connections. Perfect for dual-purpose trucks, this is a no-compromise solution that keeps your Duramax running strong under load, tune, or throttle.
