Frequently Asked Questions About Kenworth W900B/W900L Cab & Related

Will these cab parts fit both the W900B and W900L models?

Most components in this category are designed to fit both the W900B and W900L, since the two share a similar cab structure. However, there can be subtle differences between model years and cab configurations, so it is important to check the specific fitment notes on each product page or confirm with your VIN and cab style before ordering.

What materials are these cab components made from?

Depending on the specific part, you will find items made from steel, fiberglass, or ABS plastic. Steel components typically offer added durability for structural or exterior pieces, while fiberglass and ABS are common for panels and trim pieces where weight and moldability are a factor. Product descriptions will specify the material used for each item.

Do these parts come pre-painted or primed, or will I need to paint them myself?

Many cab parts are sold unpainted or in a primer finish, allowing you to match the paint to your specific truck color. Some items may be available in a gel-coat or finished surface depending on the manufacturer. Check the individual listing to confirm the finish before purchasing so you can plan for any additional paint work.

Are these OEM parts, aftermarket replacements, or both?

This category includes a mix of OEM and quality aftermarket parts. Aftermarket options are often built to match the original fit and function at a more accessible price point, while OEM parts are sourced to match factory specifications exactly. Product titles and descriptions will indicate whether an item is OEM or aftermarket.

What should I know before installing a replacement cab part?

Installation complexity varies widely depending on the part, ranging from simple bolt-on trim pieces to more involved panels that may require body work, sealing, or alignment with adjacent components. We recommend reviewing any included instructions, having basic hand tools on hand, and, for larger structural pieces, consulting with a qualified technician to ensure proper fit and sealing against water or air leaks.
