Peterbilt 357/378 Air Tanks, Wraps & Mounting

Frequently Asked Questions About Peterbilt 357/378 Air Tanks, Wraps & Mounting

Will these air tanks and mounting brackets fit my Peterbilt 357 or 378 without modification?

These products are designed to match the factory air tank dimensions and mounting locations used on the Peterbilt 357 and 378 chassis. However, because trucks can vary by year, frame configuration, and prior modifications, we recommend double-checking measurements and mounting hole patterns against your specific truck before ordering. If you're unsure, our team can help confirm fitment.

What materials are the air tank wraps and covers made from, and how do they hold up to weather and road debris?

Air tank wraps are typically offered in stainless steel or aluminum, depending on the style you choose. Stainless steel options generally offer better corrosion resistance and durability against road salt, moisture, and debris, while aluminum wraps provide a lighter-weight alternative. Both are built to withstand regular exposure to the elements, but routine cleaning will help maintain their appearance over time.

Do the air tank wraps come with pre-cut holes for drain valves, fittings, and brackets?

Most wraps are cut to accommodate standard drain valves, fittings, and mounting hardware in their factory positions. That said, exact cutout placement can vary by manufacturer and tank style, so it's a good idea to compare the product specs or images with your existing setup, especially if you've added aftermarket fittings or valves.

What finish options are available, and how do they affect maintenance?

You'll typically find these products in polished stainless steel, brushed stainless steel, or plain aluminum finishes. Polished stainless offers a mirror-like look but requires more frequent wiping down to prevent water spots and road film from dulling the shine. Brushed finishes tend to hide minor scratches and light grime better, making them a lower-maintenance choice for daily drivers.

Can I install air tank wraps and mounting hardware myself, or is professional installation recommended?

Many drivers and shop technicians install these components themselves using basic hand tools, especially when replacing an existing wrap or bracket in the same location. Installation is generally straightforward, involving removal of the old cover or mount and securing the new piece with the provided hardware. If your setup involves relocating tanks or altering mounting points, we suggest having a qualified technician handle the install to ensure everything is properly secured and road-ready.
