Frequently Asked Questions About Freightliner Cascadia 116/126 Sleeper Side Accessories

What years and models are these sleeper side accessories compatible with?

These accessories are designed specifically for Freightliner Cascadia 116 and 126 models with sleeper cabs from 2018 to current model years. The 116 models feature a BBC (Bumper to Back of Cab) of 116 inches, while the 126 models have a 126-inch BBC. Before ordering, verify your truck's exact model year and BBC measurement, as pre-2018 Cascadia models have different mounting points and dimensions that are not compatible with these accessories.

What material options are available and which holds up best against road conditions?

Most sleeper side accessories for the Cascadia come in either 304 stainless steel or chrome-plated steel. The 304 stainless steel options offer superior corrosion resistance and require less maintenance, making them ideal for trucks operating in harsh weather conditions or areas with heavy road salt usage. Chrome-plated options provide a mirror-like finish but require regular polishing and may show pitting over time. For maximum durability, we recommend 16-gauge or thicker stainless steel accessories.

Do I need to drill holes for installation, and what tools are required?

Installation requirements vary by accessory type. Most sleeper extension panels and fairings utilize existing factory mounting points and require no drilling. However, some custom light bars and additional trim pieces may require drilling 2-4 pilot holes. Basic installation typically requires a socket set (typically 10mm, 13mm, and 15mm), Phillips and flathead screwdrivers, and a drill with metal bits if holes are needed. Professional installation usually takes 1-2 hours depending on the complexity of the accessories.

Will aftermarket sleeper accessories affect my warranty or DOT compliance?

Properly installed sleeper side accessories that don't modify the truck's structural components typically won't void your warranty. However, any drilling or modifications to the sleeper cab should be documented. All accessories should maintain DOT-required reflectors and lighting visibility. Sleeper extensions and fairings must not exceed legal width limits (102 inches in most states) or interfere with required safety equipment. Always verify with your dealer and local regulations before installation.

What's the difference between sleeper fairings, panels, and extension kits?

Sleeper fairings are aerodynamic pieces that mount between the cab and sleeper to reduce wind resistance and improve fuel efficiency. Sleeper panels are decorative or protective pieces that cover the sides of the sleeper, often featuring cutouts for lights or vents. Extension kits include both functional and aesthetic components that extend the sleeper's appearance, such as side extenders that create a more seamless transition from cab to sleeper. Many drivers combine these accessories for both improved aerodynamics and enhanced appearance.
