Peterbilt 567/579 Full Fenders

Frequently Asked Questions About Peterbilt 567/579 Full Fenders

Will these full fenders fit my Peterbilt 567 or 579 without modification?

These full fenders are designed to match the body lines and wheel well dimensions of the Peterbilt 567 and 579 models. However, fitment can vary slightly depending on your truck's axle configuration, tire size, and whether you have factory or aftermarket suspension components. It's a good idea to confirm your specific chassis setup before ordering, and reach out to our team if you're unsure about compatibility with any custom modifications on your truck.

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

Full fenders in this category are typically offered in materials like fiberglass, steel, or poly composite, each with different strengths. Fiberglass offers a smooth factory-like finish and is easy to paint, steel provides added durability and resistance to impact, and poly composite options tend to resist cracking in cold weather. The best choice depends on your priorities for weight, durability, and appearance in your specific operating conditions.

Do these fenders come pre-painted, or will I need to paint them myself?

Most full fenders are sold unpainted or in a gel-coat/primed finish, allowing you to match them to your truck's exact paint color. Some options may be available in a finished gloss black or white. Be sure to check the product listing for finish details, and if painting is required, proper surface prep will help ensure a long-lasting match to your cab.

What tools or skills are needed to install full fenders on my truck?

Installation generally requires basic hand tools, and many full fenders use existing mounting points or brackets designed for a bolt-on installation. While some truck owners with mechanical experience install these themselves, others prefer having a shop handle it, especially if brackets need adjustment or if the fender requires trimming for a proper fit around tires and mud flaps.

Are full fenders required for compliance, or are they just for looks?

Full fenders serve both a functional and aesthetic purpose. They help control road spray, mud, and debris thrown up by the tires, which can improve visibility and safety for other drivers and reduce wear on nearby components. Depending on your state or region, there may be regulations regarding fender coverage and mud flap requirements, so it's worth checking local trucking regulations to ensure your setup stays compliant.
