Kenworth W990 Air Tanks, Wraps & Mounting

Frequently Asked Questions About Kenworth W990 Air Tanks, Wraps & Mounting

What is included in this category?

This category covers air tanks (also called air reservoirs) for the Kenworth W990, along with the decorative wraps or covers that dress up those tanks and the brackets, straps, and mounting hardware needed to secure them to the frame. These parts are used for both functional air system components and cosmetic upgrades that give the truck a cleaner, more custom look.

Will these air tanks and wraps fit my Kenworth W990 without modification?

Most tanks, wraps, and mounting kits listed in this category are designed to match the W990's frame dimensions and factory mounting points, but exact fit can vary by cab configuration, wheelbase, and whether your truck has factory or aftermarket tanks already installed. Always check the listed specifications and measurements against your truck before ordering, and reach out to our team if you are unsure about compatibility.

Are the wraps purely cosmetic, or do they affect the tank's function?

Air tank wraps are designed as cosmetic covers that snap or wrap around the existing tank to improve appearance with polished, textured, or patterned finishes. They are not intended to alter the tank's air storage capacity or affect the operation of your air brake or air suspension system. Proper installation is still important so the wrap does not interfere with drain valves, fittings, or mounting hardware.

What?? and finish options are available, and how do I keep them looking good?

Air tanks are typically steel, while wraps and trim pieces are commonly available in stainless steel or aluminum with polished, brushed, or diamond-plate finishes. Stainless steel generally holds up well against road grime and corrosion, but regular washing and periodic polishing will help maintain shine and prevent water spotting or surface staining over time.

What tools or steps are involved in installing a wrap or mounting kit?

Installation generally involves basic hand tools such as wrenches, sockets, and sometimes a drill if new mounting holes are required. Most wraps are designed to clamp or strap around the existing tank without needing to disconnect air lines, but mounting brackets or straps may require temporarily supporting or removing the tank. If you are replacing an entire tank and mounting assembly, it is a good idea to review your air system fittings and have basic mechanical experience or a qualified technician handle the installation.
