Tested and Tortured™ for the toughest people in the toughest industry

Minimizer is the go-to aftermarket solution for the heavy-truck industry — whether you’re a driver, owner/operator, fleet manager or technician.

We invented the poly fender, and we didn’t stop there. Over the last four decades, we’ve expanded our lineup to include: custom-molded floor mats, slick plates, tool boxes, fast flaps, and more — delivering proven durability and performance across every application.

Our distribution network spans the U.S., Canada, Mexico, and Latin America — so whether you’re in Miami or Vancouver, you can find Minimizer products at thousands of distributor locations.

At Minimizer, “Tested & Tortured” isn’t just a motto — it’s our standard operating procedure. Every product line goes through rigorous testing before earning the right to carry our industry-leading lifetime guarantee.

With more than 40 years of experience and over a million units sold (many still in service), Minimizer parts are trusted where it counts most — on semi trucks and trailers just like yours.
