Thoroughbred Diesel opened its doors for business in 2001 as a small, local diesel repair shop. The staff at that time, turned wrenches day in and day out while gaining hands on knowledge of products and how to install those products. Four years later in 2005, we entered the world wide web and launched our online store, ThoroughbredDiesel.com. In 2009 we built a new 11,000sq ft. shop with an in house dyno, conveniently located along interstate I-64 in Winchester, KY. Whether you choose to walk into our retail showroom, or pick up the phone and call us about your diesel, we take pride in giving you great customer service. We are just rednecks that know trucks at Thoroughbred Diesel and we thank each of you for your continued support of our business. Customer Service is what sets us apart from our competition.
