Fleece Performance Engineering is committed to the development and marketing of high-performance products in the automotive aftermarket. Fleece Performance Engineering was founded by Brayden and Chase Fleece in 2006 in north Salem, Indiana. Both companies are committed to constantly innovating new products and improving existing ones in the market. Brayden's 2004.5 LLY Duramax became the test bed for the development of TurboBrake and Duramax Cheetah, while Chase's 2002 Cummins was one of the first Cummins pickups to integrate the allison gearbox. As a team, it has grown with the principles of innovation, quality and customer service. Products such as cheetah turbocharger, TapShifter and TurboBrake put Fleece Performance on the map. Today, the team will continue to leverage these products and customer service capabilities, as well as develop and market innovative new products for the automotive aftermarket.
