Peterbilt 375/377 Fuel Tank Fairings

Frequently Asked Questions About Peterbilt 375/377 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 375/377, closing the gap between the tanks and the frame or cab. They give the truck a cleaner, finished look, help smooth airflow along the side of the truck, and cover the frame rails and wiring or lines that would otherwise be exposed.

Will these fairings fit my specific Peterbilt 375 or 377 tank setup?

Fit depends on your tank diameter, spacing, and mounting configuration, since these can vary from truck to truck even within the same model. Be sure to check the listed specifications and measurements for each fairing against your own setup before ordering, and reach out to us if you are unsure so we can help confirm compatibility.

What material are these fairings made from, and how do they hold up?

Fuel tank fairings are typically offered in materials such as aluminum or durable poly/composite blends, depending on the specific product. Aluminum options generally offer a polished or brushed look and good long-term durability, while poly fairings tend to be lighter and resistant to denting. Check each product listing for the exact material used.

Do these fairings come pre-drilled, and what does installation involve?

Many fairings are pre-drilled to match common factory mounting points, which simplifies installation, but some may require drilling or minor fitment adjustments depending on your truck's setup. Installation generally involves securing the fairing to the frame or existing brackets with bolts or hardware, and basic hand tools are usually all that's needed. Always double check hole alignment before final mounting.

Can I get these fairings in a polished or painted finish to match my truck?

Yes, fuel tank fairings are commonly available in a few finish options such as raw, polished aluminum, or painted to help match or complement your truck's existing look. Available finishes vary by product, so check the specific listing to see what options are offered for that particular fairing.
