Area Diesel Service, Inc. (ADS)

Established in 1973, our diesel repair and performance truck products shop has grown from a tiny, one-man show into a thriving national operation. In the early 70s, Val Leefers discovered his passion and talent for innovative diesel performance upgrades that improve fuel injection systems and repairing diesel pumps. After honing his diesel repair skills, Val built a small building just outside Carlinville, Illinois; bought $1300 in inventory; and hung out his shingle. Area Diesel Service was open for business, though business wasnt exactly booming. Val sweated out the rough early years the only way he was fit - by establishing innovative diesel performance that saves customers money over the long haul and by providing dedicated, honest service.
