Frequently Asked Questions About Kenworth W990 Cab, Sleeper & Cowl Panels

What years and models are these cab, sleeper, and cowl panels compatible with?

Our Kenworth W990 panels are designed specifically for 2018 and newer W990 models. While the W990 shares some design elements with the W900, these panels are engineered for the W990's unique cab dimensions and mounting points. Always verify your truck's VIN and model year before ordering, as Kenworth occasionally makes mid-year changes that could affect fitment.

Are these panels made from stainless steel or chrome-plated steel, and how do they hold up against rust?

We offer both 304-grade stainless steel and triple chrome-plated steel options. The stainless steel panels provide superior corrosion resistance and require minimal maintenance, making them ideal for trucks operating in harsh weather conditions or coastal areas. Chrome-plated panels offer a mirror-like finish but require regular polishing and care to prevent pitting and rust, especially around mounting holes and edges where the plating can wear.

How difficult is the installation, and what tools or modifications are required?

Installation typically takes 2-4 hours per panel for experienced technicians. You'll need basic hand tools, a drill with metal bits, and silicone sealant. Most panels use existing mounting holes, but some customization may require drilling new holes. Sleeper panels often need minor trimming around marker lights or airline connections. We recommend professional installation for sleeper extensions and full cowl replacements to ensure proper alignment and weatherproofing.

What's the difference between OEM-style and aftermarket custom panels?

OEM-style panels match factory specifications for direct replacement without modifications. Custom aftermarket panels often feature additional chrome accents, LED light cutouts, or extended coverage areas. While custom panels enhance appearance, they may require more extensive fitting and could affect warranty coverage. OEM-style panels maintain original mounting points and typically install faster with predictable results.

Do these panels come with mounting hardware and gaskets, or are those sold separately?

Most of our cab and cowl panels include basic mounting hardware like bolts and washers. However, weather stripping, rubber gaskets, and specialized brackets are often sold separately as these components vary by specific application and customer preference. Sleeper panels particularly benefit from new gasket material during installation to prevent water leaks and wind noise. We recommend ordering complete hardware kits for the best fit and finish.
