Frequently Asked Questions About Peterbilt 352 Air Tanks, Wraps & Mounting

What size air tanks fit the Peterbilt 352, and how do I know which ones I need?

The Peterbilt 352 typically accommodates air tanks ranging from 11 inches to 13 inches in diameter, with lengths varying from 24 to 30 inches depending on your frame configuration. To determine the right size, measure your existing tanks or check the available mounting space between your frame rails. Most 352 models use dual tank setups with 25-inch or 26-inch lengths. If you're running a day cab configuration, you'll have more flexibility with tank placement compared to sleeper models.

Will these tank wraps and guards fit my specific year Peterbilt 352?

Our air tank wraps and guards are designed to fit Peterbilt 352 models from 1979 through 1987. The mounting brackets and tank sizes remained consistent throughout these production years. However, if your truck has been modified with aftermarket frame extensions or custom exhaust routing, you may need to verify clearances. The universal-style wraps we carry will fit any round tank within the specified diameter range, regardless of your truck's specific year.

How difficult is it to install new air tanks and mounting brackets on a 352?

Installation typically takes 2-4 hours for someone with basic mechanical skills. You'll need standard hand tools, including wrenches for the air line fittings and a drill if new mounting holes are required. The most challenging part is usually disconnecting and reconnecting the air lines without introducing leaks. We recommend having thread sealant or Teflon tape on hand. Many customers find it easier to install one tank at a time to maintain air pressure for testing. Always drain your air system completely before beginning work.

What's the difference between aluminum and steel air tanks for my application?

Aluminum tanks are about 40% lighter than steel equivalents and won't rust, making them ideal for trucks exposed to road salt or coastal conditions. They typically cost 20-30% more than steel but can last the lifetime of your truck with proper maintenance. Steel tanks are more budget-friendly and highly durable against physical impacts, but they require regular inspection for rust, especially around the mounting brackets and drain valve areas. Most Peterbilt 352 owners choose aluminum for weight savings and longevity, particularly on restored or show trucks.

Do I need special mounting straps or brackets when upgrading my air tanks?

If you're replacing tanks with the same diameter as your originals, you can often reuse existing mounting straps and brackets if they're in good condition. However, we recommend new mounting hardware when switching tank sizes or materials. Our polished stainless steel straps not only look better but provide more even pressure distribution than worn factory straps. For Peterbilt 352s with frame-mounted tanks, ensure your brackets accommodate the 34-inch frame width. Side-mounted configurations may require offset brackets depending on your exhaust system layout.
