Frequently Asked Questions About Kenworth W900B/W900L Day Cab Conversion

What does a day cab conversion actually involve?

A day cab conversion replaces the sleeper section of a W900B or W900L with a shortened back panel and roof cap, effectively converting a sleeper truck into a day cab configuration. This typically includes a back-of-cab panel, roof skin, and the necessary trim pieces to close out the cab where the sleeper used to be, giving the truck a factory-style day cab appearance.

Will this conversion kit fit my specific W900B or W900L?

Fit can vary depending on the model year, cab width, and roof style of your particular truck, since Kenworth made changes to the W900B and W900L over the years. Always check the listed specifications and measurements against your truck, and reach out to our sales team with your VIN or cab details if you are unsure about compatibility before ordering.

What material and finish options are available?

Day cab conversion panels are commonly offered in fiberglass or aluminum, depending on the manufacturer, and typically ship in a gray or white gelcoat/primer finish ready for paint. Fiberglass panels are popular for their ability to match factory body lines, while aluminum options can offer added durability. Check the individual product listing for the exact material and finish included with your kit.

Can I install this myself, or do I need a body shop?

While experienced DIY mechanics with fabrication and bodywork skills can install a day cab conversion, most of these kits require cutting, fitting, bonding, and paint work to achieve a clean factory-look result. Because of the precision needed for panel alignment and finishing, many customers choose to have the conversion installed by a body shop or fabricator familiar with heavy truck cab work.

Does converting to a day cab affect my truck's title, weight, or resale value?

Removing a sleeper and converting to a day cab can change the truck's overall length, weight, and title description in some states, so it is worth checking with your local DMV or titling authority on any paperwork requirements. Many owners find that a properly done day cab conversion can improve resale appeal for buyers specifically seeking day cab trucks for local or regional hauling.
