In addition to providing warranty work for the products we carry, our team of experienced and well-trained technicians work on almost every type of truck, trailer and equipment, including school buses.

Our field service team is ready to respond quickly when our customers need us in an emergency. As a member of the WheelTime service network, we get them into our shop quickly, do a comprehensive inspection and deliver a diagnosis within two hours. We also have the ability to service our customers in the field on a non-emergency basis as needed. Our mobile service trucks are ready to assist customers when a need arises.

In addition to working with those customers in the transportation industry, we are also proud to meet the needs of the construction and agriculture industry throughout our area. Our technicians understand the extreme conditions these engines, transmissions and other components operate in and the impact a breakdown can have on a business. Our maintenance abilities ensure downtime is kept at a minimum and are available for emergency repairs even on weekends and holidays.
