About Alliant Power

We are your critical engine component experts

Who We Are

Alliant Power is the nation’s leading provider of premium powertrain repair components; we specialize in fuel, air, and aftertreatment parts and installation kits. Alliant Power has been fueling its customers success since 1961 and has continued to evolve over the years from a service center to a nationwide integrator for critical engine components. In 2002, our brand Alliant Power, was established as a result of a strategic partnership. From 2018 to 2022, Alliant Power extended its footprint nationwide, which expanded our distribution by having warehouses in all four time zones to meet our customers’ changing needs. Throughout the years, Alliant Power continues to strengthen its foundation, evolve with the industry, and be the solution for future repair shops.

As the industry evolves, we too will continue to grow and be ready to meet the service needs of our customers. Alliant Power is going to continue to focus on legacy and critical clean diesel components as well as the future of our employees, customers, and suppliers.

Our Purpose

We are committed to strengthening our foundation, evolving with the industry, and being the solution for future repair shops.

Our History

Alliant Power was established in 1961 as Diesel Injection Service (DIS), a fuel injection rebuild service center in south central Wisconsin. By the ‘80s and ‘90s, we expanded into diesel parts distribution and increased our distribution reach through acquisitions.

Our Partnerships

Our strong relationships with the big-name companies have made us the largest aftermarket distributor of top OE brands in the U.S. From fuel system and engine components to turbochargers, filtration products and fuel additives—we carry all the best brands.

Our Brand

Alliant Power was established in 2002 as a result of a strategic partnership with Caterpillar® Fuel Systems, granting Alliant Power exclusive rights to supply new, original equipment (OE) HEUI injectors for popular Ford® and Navistar® diesel vehicles to the aftermarket. Since 2002, the Alliant Power product line has grown considerably. We lead the aftermarket in OE or equivalent quality products: fuel systems, engine components, and complete kitting solutions. 

Our Products

Reduce sourcing and downtime with Alliant Power’s comprehensive one-stop shop of OEM and new & remanufactured products for all light duty, medium and heavy duty, off-highway and marine applications.

Community Involvement

At Alliant Power, we believe in giving back and being responsible citizens of the communities that we call home. Recognizing this social responsibility, we focus our efforts in four areas:

Ethical business practices
Environmental consciousness

Ethics— We will always conduct business with integrity and respect. Alliant Power promotes safety, respect for our employees, customers and suppliers. We work diligently to honor our internal policies, respect the law and maintain transparency and collaboration in our partnerships.

Environment— Alliant Power recognizes the need to protect the natural environment. We will follow best practices for recycling, conserving energy, using environmentally friendly technologies and products, and donating to organizations that work to protect our resources.

Philanthropy— We are committed to donating a portion of our net income to support non-profit organizations whose mission is to care for children, support veterans, and encourage athletics in our communities.

Volunteering— Alliant Power encourages our employees to volunteer. Volunteering can be done through company-organized programs or individual efforts. This has taken the form of serving meals at the local Ronald McDonald House or biking to raise money for healthy meals for those in need.
