Peterbilt 567/579 Fuel Tank Fairings

Frequently Asked Questions About Peterbilt 567/579 Fuel Tank Fairings

What are fuel tank fairings and what do they do?

Fuel tank fairings are the panels that fit between and around the fuel tanks on your Peterbilt 567 or 579, closing the gap between the tanks and the cab or chassis. They smooth out airflow along the side of the truck, help reduce drag, and give the truck a cleaner, more finished appearance while also helping to shield the tanks and related components from road debris.

Will these fairings fit my specific Peterbilt model and tank configuration?

Fit depends on your exact truck model, cab configuration, and the size and spacing of your fuel tanks, since Peterbilt 567 and 579 trucks can be ordered with different tank diameters and mounting setups. Always check the listed specifications, measurements, and compatibility notes on each product page, and compare them against your truck's actual tank setup before ordering. If you're unsure, having your VIN or tank dimensions on hand when you contact us will help ensure you get the correct fit.

What materials are these fairings made from, and how durable are they?

Fuel tank fairings are typically made from materials like fiberglass, ABS plastic, or aluminum, depending on the manufacturer and product line. Each material offers a different balance of weight, flexibility, and long-term durability against road vibration, temperature swings, and general wear, so it's worth reviewing the material listed on each specific product to match your preference for strength versus weight.

Do these fairings come pre-finished, or will I need to paint them?

Some fairings are sold in a raw or gel-coat finish that requires painting to match your truck, while others may be available primed or in a finish-ready state. Check the product description for finish details before purchase, and if color matching is important to you, plan on having the piece painted by a professional to get a seamless look with your existing paint or wrap.

What's involved in installing a fuel tank fairing, and can I do it myself?

Installation generally involves mounting the fairing using brackets, bolts, or existing mounting points near the fuel tanks and cab, and many customers with basic mechanical experience and common hand tools are able to install these themselves. That said, exact steps can vary by product and truck configuration, so we recommend reviewing any included instructions and confirming you have the correct mounting hardware before starting. If you're not comfortable with the install, a truck accessory shop or dealer service department can typically handle it for you.
