Frequently Asked Questions About Kenworth T300-T450 Sleeper Side Accessories

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

These accessories are designed specifically for Kenworth T300, T330, T370, and T450 models with sleeper cabs manufactured from 2003 to present. The mounting points and dimensions are standardized across these model years, but we recommend double-checking your VIN with our support team if your truck has aftermarket modifications or is a pre-2003 model. Note that day cab versions require different accessories due to the shorter cab configuration.

Are these accessories made from stainless steel or chrome-plated steel, and how durable are they?

Most of our Kenworth T300-T450 sleeper side accessories are available in both 304-grade stainless steel and chrome-plated steel options. Stainless steel accessories offer superior corrosion resistance and require less maintenance, making them ideal for trucks operating in harsh weather conditions or coastal areas. Chrome-plated options provide a mirror-like finish at a lower price point but may require periodic polishing and are more susceptible to pitting over time. Both materials are engineered to withstand highway vibrations and weather exposure when properly installed.

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

Installation requirements vary by specific accessory. Most sleeper panels and extenders utilize existing factory mounting points and require no drilling. However, some accessories like grab handles or additional light bars may require drilling 2-4 pilot holes. Basic installation typically requires a socket set (typically 10mm-13mm), Phillips and flathead screwdrivers, and a drill with metal bits if new holes are needed. Installation time ranges from 30 minutes for bolt-on pieces to 2-3 hours for more complex accessories. Detailed instructions are included with each product.

What styles and finishes are available for sleeper side accessories?

We offer several style options including louvered panels for ventilation, smooth panels for a clean look, and panels with integrated LED lighting. Finish options include polished stainless steel, brushed stainless steel, mirror-polished chrome, and powder-coated options in black or color-matched paints. Some accessories also feature diamond plate patterns or custom cutouts for additional personalization. Each style is designed to complement the T300-T450's squared-off cab design while improving aerodynamics.

Will these accessories affect my fuel economy or cause wind noise?

When properly installed, our sleeper side accessories are designed to improve aerodynamics by smoothing airflow around the cab-to-sleeper transition. Many drivers report a slight improvement in fuel economy (typically 0.1-0.3 MPG) and reduced wind buffeting. However, improperly installed or loose accessories can create wind noise and drag. Ensure all mounting hardware is properly torqued to specification and use the provided rubber gaskets or weather stripping to eliminate gaps that could cause whistling at highway speeds.
