Western Star 4700 Truck Fuel Tank Fairings

Frequently Asked Questions About Western Star 4700 Truck Fuel Tank Fairings

What are fuel tank fairings and what do they do?

Fuel tank fairings are the panels that fit around and beneath the fuel tanks on your Western Star 4700, streamlining the space between the tanks and the frame rails. They help smooth airflow along the underside of the truck, give the tank area a finished, factory-style look, and can help shield the tanks and mounting hardware from road debris.

Will these fairings fit my specific Western Star 4700 configuration?

Fitment depends on your truck's fuel tank size and diameter, tank spacing, and frame rail height, all of which can vary by model year and build. Before ordering, measure your tank dimensions and frame specs and compare them to the product listing, or contact our team with your VIN or build sheet so we can confirm the correct fairing set for your setup.

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

Western Star 4700 fuel tank fairings are typically offered in aluminum or poly/composite materials. Aluminum versions are commonly available in a raw mill finish for painting or a polished finish for a chrome-like shine, while poly fairings usually come in a smooth, paintable black finish. Choose based on how much maintenance you're willing to do and the look you want to match with the rest of your truck.

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

Most fuel tank fairings are designed to bolt on using existing mounting points or included brackets, so many owner-operators install them in their own shop with basic hand tools. That said, because the fairings sit close to fuel lines, straps, and tank mounts, take care when drilling or fitting hardware, and double check clearance before tightening everything down.

How do I keep polished or painted fairings looking good over time?

Polished aluminum fairings will oxidize and dull if left untreated, so regular washing and periodic polishing are needed to maintain the shine, especially in winter climates with road salt. Painted or poly fairings hold up well with routine washing, but chips or scratches should be touched up promptly to prevent corrosion or fading underneath.
