Truck Service


The durability of Cat Truck Engines is legendary. Many are still in operation after thirty years on the road—and our service staff has the training to service them. In fact, our technicians are the most experienced and best trained in the Midwest, and they’re on call 24 hours, seven days a week.

Our Cat® trained technicians are also ASE and EVT certified, able to service all makes and models of Cat-powered trucks and other domestic diesels. We are fully equipped to diagnose the latest technology incorporated in the electronic and emissions controlled engines on the road today.
