Family-owned and operated since opening in 2000, JEB Modern Machines fabricates custom performance parts and builds high-performance engines from its 20,000-square-foot facility. The Republic, Ohio, shop grew from a farming operation’s hands-on equipment experience into a CNC machining and engineering business known for diesel truck and tractor-pulling components, including turbo parts and billet accessories. Its research and development lab uses GibbsCam and CAD/CAM software, while a full-time quality control specialist inspects production.
