Kenworth T800 Fuel Tank Fairings

Frequently Asked Questions About Kenworth T800 Fuel Tank Fairings

What are fuel tank fairings and what do they do?

Fuel tank fairings are the panels that fit between the fuel tanks and the drive wheels on your Kenworth T800, running along the underside of the tanks. They smooth out the airflow along the side of the truck, help reduce road spray and debris from being kicked up onto the tanks and frame, and give the truck a cleaner, finished look. Many drivers also use them to help hide brackets, wiring, and hoses that run along the frame rail.

Will these fairings fit my specific Kenworth T800 configuration?

Fit can vary depending on your truck's fuel tank size, tank spacing, wheelbase, and the year of your T800, since Kenworth made changes to tank mounting over the years. Before ordering, check the listed tank diameter and length specifications on each product page against your own setup, and compare wheelbase or fairing length measurements when provided. If you are unsure, having your VIN and tank measurements on hand will help our team confirm the correct fit.

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

Fuel tank fairings are typically offered in aluminum, stainless steel, or poly/composite materials, each with different weight, durability, and finish characteristics. Aluminum options are lighter and often more budget friendly, stainless steel tends to hold up well against corrosion and offers a polished look, and poly/composite fairings can resist dents and are generally easier to maintain. Your choice usually comes down to the look you want, how much weight savings matters for your operation, and how the finish holds up in your typical driving conditions.

How are fuel tank fairings installed, and can I do it myself?

Most fairings mount using brackets or hardware that attach to the existing tank straps or frame, and many are designed as a bolt-on installation that an experienced DIYer can handle with common shop tools. That said, exact mounting points and hardware can differ by fairing style, so it helps to review the installation instructions or diagrams included with your specific product before starting. If your setup involves modifying brackets or working around existing wiring and hoses, a shop with truck fabrication experience can make the job go faster.

How do I keep my fairings looking good and avoid corrosion or damage over time?

Regular washing helps remove road salt, brake dust, and grime before they have a chance to sit against the surface and cause pitting or corrosion, especially on aluminum and stainless finishes. Polished stainless and aluminum fairings will need periodic polishing to maintain their shine, while painted or poly options generally just need routine washing. It's also a good idea to periodically check mounting hardware for looseness, since vibration over time can work bolts free and lead to rattling or, in worse cases, lost panels.
