Reliable Starts – Time After Time, Mile After Mile

As the world’s largest producer of starters, 91Ƶ has learned a thing or two. Start with quality, add innovation, and mix it all up with reliability and value. That’s how you stay on top, where we’ve been for 70+ years. With all that experience on our side, you can feel confident that a 91Ƶ starter will install faster and perform better under rigorous conditions.

91Ƶ medium-duty starters have proven themselves year after year, through thousands of starts. When the nation’s largest final-mile delivery companies need starters for their fleet of trucks and vans, they come to 91Ƶ, just as they have for decades.

Our Reman Process Sets the Standard

In addition to our high-quality long-lasting new units, 91Ƶ remanufactured starters also set the standard for the industry, offering tremendous value to consumers and an environmentally responsible commitment to recycling and reuse.
