Peterbilt 567/579 Rear Fenders

Frequently Asked Questions About Peterbilt 567/579 Rear Fenders

Will these rear fenders fit both my Peterbilt 567 and 579 models, and what years are compatible?

Our Peterbilt 567/579 rear fenders are designed to fit model years 2013 and newer for both the 567 and 579 series. The mounting points and dimensions are identical between these two models, making them fully interchangeable. However, pre-2013 models have different mounting configurations and will require modification or different fenders entirely. Always verify your truck's OEM and model year before ordering to ensure proper fitment.

What materials are these fenders made from, and how do they hold up against road salt and weather?

We offer rear fenders in three material options: fiberglass, stainless steel, and poly-plastic. Fiberglass fenders are lightweight and economical but require regular maintenance to prevent cracking in extreme cold. Stainless steel options provide superior durability and corrosion resistance, ideal for trucks operating in harsh winter conditions with heavy road salt exposure. Poly-plastic fenders offer the best impact resistance and won't rust or corrode, making them virtually maintenance-free. Each material has different price points, with fiberglass being most affordable and stainless steel commanding premium pricing.

Can I install these rear fenders myself, or do I need professional installation?

Installation typically takes 2-4 hours per side for someone with basic mechanical skills. You'll need standard hand tools including socket sets, drill bits for any new mounting holes, and possibly a helper for positioning. Most fenders come with mounting hardware, but you may need to reuse some existing brackets from your old fenders. The biggest challenge is usually aligning the fenders properly to maintain even gaps with the cab and ensuring the mounting brackets are secure. While professional installation isn't required, many drivers prefer it for peace of mind, especially when installing stainless steel fenders which are heavier and less forgiving during fitment.

What finish options are available, and can I paint fiberglass fenders to match my truck?

Stainless steel fenders come in mirror polish or brushed finishes. Poly-plastic fenders are available in black, white, or custom colors for fleet orders. Fiberglass fenders arrive in primer and are designed to be painted. For best results with fiberglass, we recommend professional automotive painting with proper prep work including sanding, filling any imperfections, and applying appropriate primers. Many customers successfully paint these in their shop, but color matching metallic paints can be challenging without professional equipment. Budget an additional $200-400 per fender if you're having them professionally painted.

Do these fenders come with mudflaps and mounting brackets, or are those sold separately?

Rear fenders typically come with basic mounting brackets but not mudflaps or mudflap hangers. You'll need to purchase mudflap hangers separately based on your preference for standard or anti-sail designs. Most customers reuse their existing mudflaps if they're in good condition, but new mudflaps sized appropriately for your fender choice are available. Some premium stainless steel fenders include integrated mudflap hangers, so check product descriptions carefully. Light bars, additional brackets for accessories, and fender liners are always sold separately.
