Frequently Asked Questions About Kenworth T700 Fairings & Steps

Will these fairings and steps fit my specific year model Kenworth T700?

Most aftermarket fairings and steps for the Kenworth T700 are designed to fit model years 2008-2019. However, there can be variations between early production models (2008-2010) and later models (2011-2019), particularly in mounting hole patterns and bracket designs. Always verify the specific year range listed for each product, and when in doubt, contact us with your VIN number so we can confirm compatibility with your exact truck configuration.

What's the difference between fiberglass and ABS plastic fairings, and which should I choose?

Fiberglass fairings are typically more durable and resistant to cracking in extreme temperatures, but they're heavier and more expensive. ABS plastic fairings are lighter weight, more flexible (which helps prevent cracking from vibration), and generally cost less. For trucks operating in extreme cold climates or rough terrain, fiberglass tends to perform better long-term. ABS plastic is ideal for highway applications and moderate climates. Both materials can be painted to match your truck.

Can I install these fairings and steps myself, or do I need professional installation?

Most fairings and steps can be installed by someone with basic mechanical skills and standard tools. Installation typically requires drilling mounting holes (if not pre-existing), basic hand tools, and 2-4 hours of time. Step installations are generally straightforward with bolt-on brackets. Fairing installations may require more precise alignment and sometimes minor trimming for perfect fitment. We recommend having a helper for larger fairing pieces. Professional installation typically runs $200-400 if you prefer to have it done at a shop.

Do aftermarket fairings affect fuel economy, and are they as effective as OEM parts?

Quality aftermarket fairings can provide similar aerodynamic benefits to OEM parts when properly installed. Most drivers report fuel savings of 0.2-0.5 MPG with a full fairing kit, though results vary based on driving conditions and speeds. The key is ensuring proper fitment with no gaps or misalignment that could create drag. While OEM fairings may have slight advantages in wind tunnel testing, the real-world difference is minimal when comparing to well-designed aftermarket options.

How do I match the finish and color to my existing truck, and can these parts be painted?

Most fairings come in either raw primer finish (ready to paint) or standard colors like white, black, or gray. Both fiberglass and ABS plastic fairings can be professionally painted using automotive paint systems. For exact color matching, provide your paint code to a body shop. The primer finish options allow for the best paint adhesion and color match. Pre-colored options work well if you're not concerned about exact matching or plan to create a two-tone look. Steps typically come in polished aluminum, chrome, or powder-coated finishes that complement most truck colors.
