Kenworth W900B/W900L Fuel Tank Fairings

Frequently Asked Questions About Kenworth W900B/W900L 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 Kenworth W900B or W900L, closing the gap between the tanks and the cab or sleeper. They give the truck a cleaner, finished look, help smooth airflow along the side of the truck, and cover the framerail area so hoses, wiring, and mounting hardware are not left exposed.

Will these fairings fit my specific W900B or W900L?

Fit can vary depending on tank size, spacing, and whether your truck has a sleeper or day cab configuration, so it is important to check the listed specifications and measurements against your truck before ordering. If you are unsure, having your VIN or your current fairing dimensions on hand will make it much easier to confirm a correct match with our team.

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

Fuel tank fairings in this category are typically offered in materials like aluminum or poly/composite construction, depending on the specific part. Finish options generally range from raw or unpolished to polished or painted-ready, so you can choose based on how much finishing work you want to do yourself versus having a piece that is closer to install-ready.

How difficult is it to install a fuel tank fairing?

Installation generally involves mounting brackets or existing hardware on the truck and lining the fairing up between the tanks and the cab or sleeper. Most fairings are designed to use factory-style mounting points, but some trimming, drilling, or bracket adjustment is common on trucks that have aftermarket tanks or non-stock spacing. Having basic hand tools and a second person to help hold the panel in place during fitting makes the job easier.

How do I keep a polished fairing looking good over time?

Polished aluminum fairings will oxidize and dull over time if left untreated, especially with road salt, dirt, and weather exposure. Regular washing and periodic re-polishing with a quality metal polish will keep the shine up, and applying a wax or sealant after polishing can help extend the time between polishing sessions.
