Peterbilt 387 Air Tanks, Wraps & Mounting

Frequently Asked Questions About Peterbilt 387 Air Tanks, Wraps & Mounting

What is the difference between an air tank and an air tank wrap?

The air tank itself is the storage cylinder that holds compressed air for your truck's brake and suspension systems. An air tank wrap is a decorative cover, typically made of stainless steel or aluminum, that fits around the outside of the tank to protect it from road debris and give it a polished, finished look. Wraps do not replace the tank but are installed over it.

Will these air tanks and wraps fit my Peterbilt 387 without modification?

Products listed in this category are designed to match the factory tank dimensions, mounting bolt patterns, and bracket locations used on the Peterbilt 387. That said, tank sizes and mounting setups can vary depending on your truck's build year and configuration, so it is a good idea to compare the measurements and mounting hole spacing of your current setup with the product specifications before ordering.

What materials and finishes are available for air tank wraps?

Air tank wraps are commonly offered in stainless steel or aluminum, with finish options ranging from brushed and polished to diamond plate textures. Stainless steel wraps generally hold up well against corrosion and are easier to keep polished, while aluminum options are lighter in weight. The best choice often comes down to the look you want and how much maintenance you are willing to put in to keep it looking new.

What mounting hardware and brackets are included?

Most air tanks and wraps come with the basic hardware needed for a standard installation, but this can vary by manufacturer and specific product. Always check the product listing for what is included, and inspect your existing mounting brackets and straps for wear or damage before reinstalling, since reusing worn hardware can lead to a loose or unstable tank mount.

Can I install an air tank or wrap myself, or do I need a professional?

Many drivers and fleet technicians with mechanical experience are able to install air tank wraps themselves, since they typically just wrap around the existing tank and secure with clamps or provided hardware. Replacing an actual air tank involves working with the truck's air brake system, so if you are not comfortable disconnecting and reconnecting air lines properly, it is worth having a qualified technician handle that portion of the job to ensure the brake system remains safe and fully functional.
