Coan Engineering joins the NMCA in 2018 as sponsor of the popular and expanding Stock and Super Stock class, which made its NMCA debut last year. Manufacturing a diverse line of Performance Transmissions, Torque Converters and components for the street, strip, and circle track applications, Coan has been a leader in the drag racing world for more than 40-years. When we added this class to our lineup, we knew it would be a popular addition, said National Event Director, Rollie Miller. Coan has supported classes like this for as long as I can remember, so I think it's a great fit for the NMCA, Coan, and obviously those who race the class, Miller added.
