Frequently Asked Questions About Freightliner Cascadia 113/125 Sleeper Side Accessories

Will these sleeper side accessories fit my specific Cascadia model year?

Our sleeper side accessories are designed to fit Freightliner Cascadia models from 2008 to present, covering both the 113 and 125 sleeper configurations. However, there are slight variations between pre-2018 and 2018+ models due to the New Cascadia redesign. When ordering, please specify your exact model year to ensure proper fitment. The mounting holes and contours differ slightly between generations, so using the correct year-specific parts is essential for a clean installation.

What material are these accessories made from, and how durable are they?

Most of our Cascadia sleeper side accessories are manufactured from either 304 stainless steel or heavy-duty ABS plastic, depending on the specific product. Stainless steel options offer superior corrosion resistance and typically last 10-15 years with minimal maintenance. ABS plastic accessories are lighter weight and more affordable while still providing excellent durability against road debris and weather. All chrome-plated options feature triple-chrome plating over steel for maximum shine and longevity.

How difficult is the installation, and what tools will I need?

Installation difficulty varies by product, but most sleeper side accessories can be installed in 1-3 hours with basic hand tools. You'll typically need a drill with metal bits, socket set, screwdrivers, and masking tape for alignment. Some accessories use existing mounting points, while others require drilling new holes. We recommend having a second person assist with larger panels to ensure proper alignment. Professional installation usually runs $150-300 if you prefer not to DIY.

What styles and finishes are available for sleeper extensions and panels?

We offer several finish options including mirror-polished stainless steel, brushed stainless, chrome-plated steel, and painted ABS to match factory colors. Style options range from plain panels to those with integrated LED lighting, louvered vents, or diamond plate patterns. The most popular choices are the 6-inch and 8-inch sleeper extensions in polished stainless, which provide a clean, professional appearance while protecting the cab-to-sleeper gap from road grime.

Do these accessories affect aerodynamics or fuel efficiency?

Properly installed sleeper side accessories typically have minimal impact on fuel efficiency - usually less than 0.5% change in mpg. Some accessories, like sleeper fairings and extenders, can actually improve aerodynamics by smoothing airflow around the cab-to-sleeper transition. However, accessories that protrude significantly or create turbulence (like some light bars or antennas) may cause a slight decrease in fuel efficiency at highway speeds. We recommend choosing flush-mount or aerodynamically designed options if fuel economy is a primary concern.
