Welcome to Diesel Forward

We started as a small, family-owned diesel repair service more than 50 years ago. Since then we’ve grown to become a family of three business units with expertise in every link of the aftermarket diesel supply chain.

Today, Diesel Forward includes DIS Distribution, a large supplier of aftermarket diesel parts serving the Midwest and Northeast corridor of the United States; Alliant Power, a name synonymous with quality in the diesel parts aftermarket; and Diesel Injection Service, an on-site and mobile service center with the best trained and most experienced technicians in the business.

Call us. We’re your one-stop shop for all things diesel.
