Freightliner Classic Fuel Tank Fairings

Frequently Asked Questions About Freightliner Classic 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 Freightliner Classic, closing the gap between the tanks and the cab or sleeper. They smooth out the airflow along the side of the truck, help reduce wind drag around the tanks, and give the side of the rig a clean, finished look while also helping to shield the tanks from road debris.

Will these fairings fit my specific Freightliner Classic configuration?

Fit depends on your truck's tank size, spacing, and cab/sleeper combination, since Freightliner Classics were built with different tank diameters and mounting configurations over the years. Before ordering, check the listed tank size and mounting details against your truck, and measure the gap between your tanks and cab to confirm the fairing will bridge it correctly. If you are unsure, our team can help you match the correct fairing to your setup.

What materials and finish options are available?

Fuel tank fairings are typically offered in aluminum or poly/composite material, with finish options ranging from raw or unpolished to a polished or chrome-look finish. Aluminum fairings are generally lighter and take a shine well, while poly versions tend to resist minor dents and dings. Choose based on how much maintenance you're willing to do to keep the finish looking good and the level of shine you want to match the rest of your truck.

How difficult is it to install a fuel tank fairing myself?

Most fairings mount using brackets and hardware that bolt to the existing tank straps or frame points, so installation is generally straightforward with basic hand tools. That said, getting the fit tight and even on both sides can take some patience, especially if your truck's tanks have shifted slightly over time. If you're not comfortable with fabrication or minor bracket adjustments, having a shop install it will ensure a cleaner result.

How do I keep my fairing looking good over time?

For polished aluminum fairings, regular washing and periodic polishing will help prevent oxidation and keep the shine, especially if the truck sees winter road salt or heavy highway grime. For poly or painted fairings, routine washing is usually enough, but touch-up paint may be needed if the surface gets chipped by road debris. Keeping hardware and brackets free of rust will also help the fairing sit properly and last longer.
