Area Diesel Service, Inc
1300 University Street , Carlinville, Illinois, United States

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 improving 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 his shingle. Area Diesel Service was open for business, though business wasn't exactly booming.

Val sweated out the rough early years the only way he saw fit—by establishing innovative diesel performance and providing dedicated, honest service. By remaining true to those core values, Area Diesel earned its place as a leader in the Midwest diesel market and later looked to expand on that success.

About Our Dealers

Those of us at Area Diesel Service pride ourselves on the fact that we don't operate like a lot of other businesses out in the marketplace. But one thing we do have in common with most other businesses is the desire to put our products in front of each and every potential buyer. But come on, this is the real world and we know that we simply can't do that. So we rely on our extensive network of dealers throughout the country to help us accomplish that goal. We pass on volume discounts and dealer only specials to a select group of folks that are out there working hard to take care of the vast amount of diesel cars, trucks, tractors and semi's that keep this economy rolling.
