Frequently Asked Questions About Peterbilt 389 Glider Fuel Tank Fairings

Will these fuel tank fairings fit my specific year Peterbilt 389 glider?

Our Peterbilt 389 glider fuel tank fairings are designed to fit 2008 and newer Peterbilt 389 models. However, glider kits can have variations depending on the donor components used. We recommend measuring your tank mounting brackets and comparing them to our product specifications, or calling our tech support at 1-888-875-7787 with your VIN number for verification. Most fairings will fit standard 26-inch diameter fuel tanks with 120-150 gallon capacity.

What material are these fairings made from, and how durable are they?

Most of our Peterbilt 389 fuel tank fairings are manufactured from either 16-gauge polished stainless steel or heavy-duty ABS plastic with chrome plating. Stainless steel options offer superior durability and resistance to road salt and chemicals, while ABS plastic fairings are lighter weight and more budget-friendly. Both materials are designed to withstand highway speeds and weather conditions. Stainless steel fairings typically carry a lifetime warranty against rust, while chrome-plated versions usually have a 1-3 year finish warranty.

Do I need any special tools or modifications to install these fairings?

Installation typically requires basic hand tools including wrenches, sockets, and drill bits. Most fairings use existing mounting points on your fuel tank straps, though some models may require drilling 2-4 new holes. Installation time averages 2-3 hours per side. No cutting or welding is required. We include detailed instructions with each set, and many customers with moderate mechanical experience successfully complete the installation themselves. Professional installation typically costs $200-400 if you prefer to have a shop handle it.

What styles and finishes are available for 389 glider fairings?

We offer several styles including full-wrap fairings that cover the entire visible portion of the tank, half-moon designs that cover just the front section, and aerodynamic teardrop styles. Finish options include mirror-polished stainless steel, chrome-plated, painted to match your truck color, and brushed aluminum. Some models feature LED light cutouts or reflective tape channels for added visibility. The choice often depends on whether you want a classic look or more modern aerodynamic styling.

How do these fairings affect fuel tank access and maintenance?

Quality fuel tank fairings are designed with maintenance in mind. Most models feature removable panels or hinged sections that allow access to fuel caps, drain valves, and tank straps without removing the entire fairing. Look for designs with quick-release fasteners or spring-loaded latches for easier access. Some drivers report that fairings actually make cleaning easier by providing a smooth surface versus exposed tank straps and brackets. Just ensure you can still perform visual tank inspections as required by DOT regulations.
