Kenworth T680 Fairings & Steps

Frequently Asked Questions About Kenworth T680 Fairings & Steps

Will these fairings and steps fit my specific Kenworth T680 model year?

Kenworth T680 fairings and steps are typically designed to fit specific production years, since Kenworth has updated the T680 body style over time. Always check the fitment details listed on each product page, including cab configuration and model year range, before purchasing. If you are unsure, have your VIN and truck specs on hand so our team can confirm compatibility.

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

Fairings are commonly made from ABS plastic or fiberglass, while steps are often constructed from aluminum or steel for added strength. Material choice affects both weight and durability, so consider your climate and how the truck is used. Aluminum steps tend to resist corrosion well, while fiberglass fairings offer a smooth factory-matching finish.

Do these parts come pre-painted, or will I need to paint them myself?

Some fairings are available in gel-coated or primed finishes ready for paint matching, while others come unpainted. Steps are usually offered in raw aluminum, painted, or powder-coated finishes. Check each listing to see what finish is included, since this affects both appearance and any additional prep work needed before installation.

How difficult is it to install these fairings and steps myself?

Installation difficulty varies by part. Steps generally bolt on using existing mounting points and factory hardware, making them a straightforward DIY project with basic tools. Fairings can require more careful alignment and sometimes additional brackets or hardware, so following the included instructions closely and having a second set of hands can make the process smoother.

Will adding aftermarket fairings or steps affect fuel efficiency or airflow?

Fairings are often designed to improve aerodynamics by smoothing airflow around the cab and reducing drag, which can help with fuel efficiency over time. Steps are primarily functional for access rather than aerodynamics, though poorly fitted or oversized steps could slightly disrupt airflow. Choosing parts designed specifically for the T680 helps maintain the intended aerodynamic benefits.
