Minimizer TR4020 Series Poly Fender Set for 48 in. Tandem Axle Spread

The MINTR4020 Poly Fender is manufactured using a proprietary material and thermoformed using proprietary technology. Designed with a unique outer lip, Minimizer fenders provide superior control of spray and debris off the tires. That means clean, damage-free freight and a safer environment for you and other drivers on the road. When dented or crushed they bounce back into shape. The material is extremely durable, impervious to salt and corrosion, and can withstand temperatures ranging from -100º F to 197º F..

The award-winning Minimizer never stops innovating. We now go head-to-head with shiny metal fenders (that bend and break) with the introduction of the new Minimizer Mirror Finishes. You get the remarkable shine and reflection of a metal fender combined with the durability and advantages of our standard Minimizer Poly Fenders. And now we’ve launched the new Minimizer Carbon Fiber Poly! This new look adds a unique style to any truck and trailer.

Our moniker boasts we manufacture the lightest truck fenders on the market. What does that mean to you? A lighter fender means better gas mileage, performance and efficiency. You want to be carrying loads not heavy fenders.
