NOTE: With the current state of affairs affecting the entire world with fear of illness and the massive effect it’s had on the economy, we have diminished all importing of US goods unless absolutely necessary. Not out of any kind of fear, but in an effort to wait until the Canadian dollar improves so I can continue to offer the best possible pricing for top quality imported goods. You may experience prolonged delays for non stock items, but upon request, I will gladly expedite required parts. Thank you for your understanding and ongoing support

Their History:

2008:   Fleece Performance Engineering was established in North Salem, IN by Brayden and Chase Fleece. Both had a passion for continuously innovating and improving upon products already on the market. Brayden’s 2004.5 LLY Duramax became the test bed to develop the TurboBrake and Duramax Cheetah, while Chase’s 2002 Cummins was one of the first Cummins pickups to integrate an Allison Transmission.

2012:  Fleece Performance upgrades both facility and location by relocating to Nitro Alley in Brownsburg, IN situated among some of the top racing leaders of the world.

2014: Fleece Performance acquires the area’s premier engine machine shop, Freedom Racing Engines. The acquisition enables Fleece Performance to expand the engine development program and product offerings. Today, Fleece Performance and Freedom Racing Engines build some of the most competitive engines in the industry.

2018: Fleece Performance breaks ground on a new 75,000 sq ft facility in Pittsboro, IN.

2019: Fleece Performance and Freedom Racing Engines re-locates to it's new facility in Pittsboro, IN. The all new headquarters provides additional space for product development, production and work areas, assembly and testing, a larger warehouse, as well as four engine dynamometers, and two-story office space.
