Freightliner Cascadia 113/125 Fairings & Steps

Frequently Asked Questions About Freightliner Cascadia 113/125 Fairings & Steps

Will these fairings and steps fit both the Cascadia 113 and 125 models?

Most products in this category are designed to fit both the 113 and 125 wheelbase versions of the Cascadia, but fitment can vary by model year and cab configuration. Always check the specific product listing for year and model compatibility before ordering, and reach out to our team if you are unsure about your truck's exact specs.

What materials are these fairings and steps made from, and how do they hold up over time?

Fairings are typically molded from durable ABS plastic or fiberglass, while steps are commonly built from aluminum or steel with a diamond-plate or non-slip surface. Aluminum steps resist rust well, while steel steps offer added strength but may require a protective coating to prevent corrosion over time. Fairings are generally designed to withstand road debris, weather, and everyday wear without cracking or fading.

Do these fairings and steps come primed and painted, or will I need to finish them myself?

Many fairings ship in a raw or primed finish, meaning you will likely need to paint them to match your truck. Some manufacturers offer pre-painted options in common factory colors, so check the product description to see what finish is included before you buy. Steps are usually sold in a natural aluminum, black powder-coat, or diamond-plate finish that does not require additional painting.

Are these parts a direct bolt-on replacement, or will I need to modify my truck to install them?

Most fairings and steps in this category are designed as direct replacements that use the factory mounting points, so no cutting or drilling is typically required. That said, some aftermarket designs may have slight variations from OEM parts, so it is a good idea to review installation instructions or reach out to our support team if you have questions about hardware or mounting brackets.

Will replacing my fairings or steps affect fuel efficiency or ground clearance?

Fairings are designed to maintain the aerodynamic profile of your Cascadia, so a properly fitted replacement should not negatively impact fuel efficiency. Steps are built to match factory height and clearance specs, so they should not interfere with ground clearance or turning radius when installed correctly. If you are switching to a different style or size than your factory equipment, double check the dimensions against your original parts first.
