When we first met the Fleece brothers, they were operating out of a (VERY busy) 54x60-foot pole barn. 15 years later, you can’t miss their 225,000 square-foot facility on the north side of I-74 outside Pittsboro, Indiana. There, they build dyno-proven and championship-winning Freedom Racing engines, manufacture problem-solving parts for each of The Big Three diesels, and produce what is arguably the most successful line of drop-in turbochargers in the industry (“Cheetah”). Now, you can find their American-made, top-quality repair products and upgrades in over a dozen Witt Family NAPA auto parts store locations throughout Indiana, Michigan, and Ohio.

Additionally, today Fleece has formally announced its acquisition of Concept Performance, a premier manufacturer of aluminum LSR and LTR builder blocks. This means dedicated foundry locations will also now exist under the Fleece Performance Engineering umbrella.
