Fleece Performance

Fleece Performance Engineering has established itself as a leading manufacturer of innovative diesel performance products, with a strong focus on improving the power, reliability, and drivability of Cummins, Duramax, and Power Stroke applications. Founded in 2008 by Brayden and Chase Fleece, the company grew from a small operation focused on solving real-world diesel performance problems into a large-scale manufacturer with engineering, machining, fabrication, and testing capabilities. Fleece is particularly well known for its Cheetah® turbochargers, which use application-specific compressor and turbine technology to improve turbo response, airflow, EGT control, and overall power potential while maintaining a drop-in style installation for many applications. The company's product lineup extends well beyond turbochargers, including PowerFlo® lift pumps, fuel-system components, turbo installation hardware, intake and airflow upgrades, electrical components, cooling products, and other diesel-specific solutions designed around common issues found on modern and older diesel trucks. Fleece products are available across popular Ford Power Stroke, GM Duramax, and Ram Cummins platforms, giving diesel owners access to application-specific upgrades for both performance builds and dependable daily-driven trucks. With ISO 9001:2015 certification, extensive in-house manufacturing capabilities, and a continued emphasis on developing solutions before common problems become widespread, Fleece Performance has become a trusted choice for diesel enthusiasts, technicians, and truck owners looking for thoughtfully engineered components that improve performance while addressing the reliability demands of real-world diesel applications.
