Thoroughbred Diesel opened in 2001 as a one bay shop in Winchester, KY. We operated our shop on three simple ideas; impeccable customer service, lowest possible prices, and fast delivery. We specialized in diesel performance and diesel stock replacement installs. Through our years as strictly a service and performance garage we realized that people all over the country need a place they could trust to call and get free honest advice about their diesel vehicles. It was shortly after that we launched our website and began our "Call For Free Advice" slogan. At Thoroughbred Diesel we know more than just the part numbers, we know the parts. We are still a real shop located in Winchester Kentucky that specialize in diesel performance and diesel repair and, we still offer free advice.
