Frequently Asked Questions About Freightliner Columbia 112/120 Fuel Tank Fairings

What years and models of Freightliner Columbia are these fuel tank fairings compatible with?

These fuel tank fairings are designed specifically for Freightliner Columbia 112 and 120 models manufactured from 2001 to 2015. They fit both single and dual fuel tank configurations. However, trucks with aftermarket fuel tanks or custom modifications may require additional fitment verification. We recommend checking your VIN or contacting us with your truck's specifications if you're unsure about compatibility.

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

Most fuel tank fairings for the Columbia are manufactured from either high-grade ABS plastic or fiberglass. ABS plastic fairings typically weigh 15-20 pounds and offer excellent impact resistance and UV stability. Fiberglass options are slightly heavier at 20-25 pounds but provide superior strength and can better withstand road debris. Both materials are designed to handle temperature extremes from -40?F to 140?F without cracking or warping.

How difficult is the installation process, and what tools are required?

Installation typically takes 2-3 hours per side for someone with basic mechanical skills. You'll need a drill with 3/8" and 1/2" bits, a socket set, and basic hand tools. The fairings mount using existing frame holes when possible, though some drilling may be required depending on your truck's configuration. Most fairings include mounting hardware and detailed instructions. Professional installation usually runs $150-300 if you prefer to have a shop handle it.

What finish options are available, and can they be painted?

Fuel tank fairings come in several finish options including primer-ready gray, gloss black, and chrome-look ABS. The primer-ready versions are ideal if you want to paint-match your truck's color. Chrome-look fairings feature a triple-plated finish that resists rust and maintains shine. All plastic fairings can be painted using automotive-grade plastic primers and paints. We recommend light sanding with 400-grit sandpaper before painting for optimal adhesion.

Will aftermarket fairings affect my fuel tank access or maintenance?

Quality fuel tank fairings are designed with maintenance access in mind. Most feature removable panels or cutouts that allow access to fuel caps, drain valves, and tank straps without removing the entire fairing. Some models include hinged access doors for frequently serviced areas. When ordering, specify if you have auxiliary equipment like APUs or hydraulic tanks that might require special access considerations.
