Frequently Asked Questions About Peterbilt 567/579 Fairings & Steps

Will these fairings and steps fit my specific Peterbilt 567 or 579 model year?

Most aftermarket fairings and steps for Peterbilt 567/579 models fit trucks manufactured from 2013 to present. However, there are slight variations between model years, particularly in mounting hole patterns and bracket designs. Always verify compatibility by checking your truck's specific model year and VIN details. For 2013-2017 models, some fairings may require additional mounting brackets, while 2018+ models often have updated mounting points. When in doubt, contact us with your VIN number for exact fitment confirmation.

What materials are these fairings made from, and how durable are they compared to OEM parts?

Our fairings are primarily constructed from high-grade ABS plastic or fiberglass-reinforced polymer, designed to match or exceed OEM specifications. ABS plastic fairings offer excellent impact resistance and flexibility in extreme temperatures (-40?F to 180?F). Fiberglass options provide superior rigidity and are ideal for heavy-duty applications. Both materials feature UV-resistant coatings to prevent fading and cracking. Steps are typically made from aluminum tread plate or diamond plate steel with anti-slip surfaces rated for 500+ pounds.

Can I install these fairings and steps myself, or do I need professional installation?

Most fairings and steps can be installed with basic hand tools and mechanical knowledge. Installation typically takes 2-4 hours per side. You'll need standard tools including socket sets, drill bits (for some applications), and torque wrenches. Pre-drilled fairings bolt directly to existing mounting points, while some universal options may require drilling. Steps usually mount to existing frame brackets. We provide detailed installation instructions with each product. Professional installation is recommended for custom applications or if you're uncomfortable with drilling into your truck's body.

What finish options are available, and can fairings be painted to match my truck?

Fairings come in several finish options: raw black ABS (paintable), primed gray (ready for paint), chrome-look ABS, and stainless steel look. Raw and primed fairings can be painted using automotive-grade paints after proper surface preparation with adhesion promoter. Chrome and stainless finishes feature durable metallic coatings that resist peeling and corrosion. Steps are available in polished aluminum, brushed aluminum, powder-coated black, or chrome-plated steel finishes. All finishes are designed to withstand road chemicals, salt, and weather exposure.

What's the difference between OEM replacement and aftermarket universal fairings?

OEM replacement fairings are designed to exact factory specifications with precise mounting points and dimensions for specific model years. They install using existing holes and brackets without modifications. Universal aftermarket fairings offer broader compatibility but may require minor adjustments, additional brackets, or drilling for proper fitment. OEM replacements typically cost 20-40% more but guarantee perfect fit. Universal options provide better value and often include upgraded features like additional LED light cutouts or improved aerodynamic designs. Both meet DOT requirements when properly installed.
