Peterbilt Quarter Fenders

Frequently Asked Questions About Peterbilt Quarter Fenders

What are quarter fenders and what part of the truck do they cover?

Quarter fenders are the curved fender panels that mount over the rear drive wheels of a semi truck, covering half or a quarter of the tire and wheel assembly. They help block road spray, mud, and debris from being thrown up by the rear tires, protecting the truck frame, hoses, and wiring, as well as other vehicles on the road.

Will these quarter fenders fit my specific Peterbilt model?

Fit can vary depending on your Peterbilt model, chassis configuration, and wheelbase, as well as tire and wheel size. Before ordering, check the product listing for specific model compatibility and measure your existing fender mounting area or reference your truck's manual. If you are unsure, our team can help confirm fitment before you buy.

What materials are these quarter fenders made from, and how do they hold up over time?

Peterbilt quarter fenders are commonly available in materials such as stainless steel, aluminum, and durable poly or composite blends. Stainless and aluminum options tend to offer a long-lasting shine and resistance to corrosion, while poly fenders are lightweight and resistant to cracking from road debris impact. The right choice often depends on your priorities around weight, appearance, and long-term durability in your operating environment.

What finish options are available, and how do I keep them looking good?

Finishes typically include polished stainless steel, brushed stainless, and painted or powder-coated surfaces, depending on the manufacturer and material. Polished stainless will require regular cleaning and periodic polishing to maintain its shine and prevent water spotting or road film buildup, while painted or textured finishes generally need less maintenance but should still be washed regularly to remove salt, grime, and brake dust.

Do these quarter fenders come with mounting hardware and brackets, and are they straightforward to install?

Many quarter fender kits include the necessary mounting brackets and hardware, but this can vary by product, so it is worth checking the specific listing before ordering. Installation generally involves securing the fender to the frame or existing mounting points using brackets, and most kits are designed for a straightforward bolt-on installation, though having basic tools and, in some cases, a second person to help hold the fender in place during mounting is recommended.
