Why Add stainless Steel Light-Hole Fairings?

Find premium fuel tank fairings designed to fit your classic Peterbilt 379. We carry different lengths, depending on the size of your Peterbilt fuel tank, ranging from 53 inches to 67.4 inches. It’s a purely aesthetic upgrade that can make your big rig stand out just a little bit more. Here’s why you should invest in fuel fairings: - Moderately improve fuel efficiency with better aerodynamics and minimal drag. - Added fuel tank protection from road debris. - A sleek, finished look to your truck. - Add more lighting options to your exterior. You can choose from durable stainless steel or high-quality composite material, ensuring that your investment lasts for years to come. These fairings also come with various marker lighting styles, from the bulls-eye style to M1 light-hole cutouts. Or you can buy an extra set of Peterbilt 379 marker lights and add them to your existing fairing’s light holes.

Frequently Asked Questions About Peterbilt 379 Fuel Tank Fairings

What are fuel tank fairings and what do they do?

Fuel tank fairings are the panels that fill the gap between the fuel tanks and the frame rails on a Peterbilt 379, running along the underside of the tanks toward the rear of the cab. They smooth out the airflow along the chassis, help reduce road spray and debris buildup around the tanks, and give the truck a finished, streamlined look under the doors.

Will these fairings fit my truck's specific fuel tank size and configuration?

Fit depends on your tank diameter, tank spacing, and wheelbase, since Peterbilt 379s were built with a variety of fuel tank sizes over the years. Before ordering, measure your existing tank diameter and the distance between the tanks and frame, then compare those measurements to the product specs listed on each fairing to confirm a proper match.

What materials are these fairings made from, and which one should I choose?

Fuel tank fairings are typically offered in aluminum or stainless steel, and sometimes in a poly or composite material. Aluminum is lighter and easier to work with, stainless offers added durability and a brighter finish, and composite options can resist minor dents and corrosion. Your choice usually comes down to budget, desired appearance, and how much wear and tear the fairing will see from road debris.

Can I install fuel tank fairings myself, or do I need a shop?

Many owner-operators install these themselves using basic hand tools, since the fairings generally bolt or clamp into place using existing mounting points or brackets. That said, if your truck has non-standard tank mounts or you're not comfortable working underneath the vehicle, having a shop handle the install can help ensure proper alignment and a secure fit.

How do I keep the fairings looking good and prevent corrosion or damage?

Regular washing to remove road salt, grime, and brake dust goes a long way, especially for aluminum and stainless pieces. Polishing stainless or aluminum fairings periodically helps maintain shine and can prevent surface oxidation. Inspect mounting hardware occasionally too, since vibration over time can loosen bolts or clamps and lead to rattling or shifting.
