About Thoroughbred Diesel

Thoroughbred Diesel began as a business that thrived in the diesel repair market, for local folks in Winchester Kentucky since 2001. This allowed the team to really get hands on experience with diesel trucks and gave them the ability to diagnose diesels over the phone. The company expanded with their online store, in 2005. In 2009 they built a new 11,000sq ft. shop with a in house dyno, conveniently located along interstate I-64 in Winchester, KY. Whether you choose to walk into their retail showroom, or pick up the phone and call them about your diesel they will give you great customer service.
