Frequently Asked Questions About Peterbilt 567/579 Air Tanks, Wraps & Mounting

Will these air tanks and mounting brackets fit my specific Peterbilt 567 or 579 model year?

Most air tanks and mounting hardware are designed to fit Peterbilt 567 and 579 models from 2013 to present. However, there can be variations based on your truck's configuration, especially between day cab and sleeper models. We recommend checking your existing tank dimensions and mounting hole patterns before ordering. The standard tank sizes are typically 11" x 25" or 11" x 36", but always verify your specific setup. If you're unsure, contact us with your VIN and we can help confirm compatibility.

What's the difference between aluminum and steel air tanks, and which should I choose?

Aluminum tanks are lighter (reducing overall vehicle weight by 15-20 pounds per tank), resist corrosion better, and typically last longer in harsh weather conditions. Steel tanks are more affordable upfront but may require more maintenance and are prone to rust, especially in areas using road salt. For most over-the-road applications, aluminum tanks provide better long-term value despite the higher initial cost. Steel tanks work well for local applications where weight isn't as critical.

Can I install these air tanks and mounting brackets myself, or do I need a shop?

Installation typically requires basic mechanical skills and can be completed in 2-4 hours with standard tools. You'll need wrenches, a torque wrench, and potentially a drill if new mounting holes are required. The most challenging part is usually disconnecting and reconnecting air lines properly to avoid leaks. Always depressurize the system completely before starting. Many drivers successfully complete this installation themselves, but if you're uncomfortable working with air systems, professional installation is recommended for safety.

What air tank wrap finishes are available, and how durable are they?

Tank wraps come in polished stainless steel, chrome-plated steel, and powder-coated options. Polished stainless steel offers the best durability and maintains its appearance with minimal maintenance. Chrome looks excellent initially but may pit or peel over time, especially in winter conditions. Powder-coated wraps provide good protection but may chip if struck by road debris. Most wraps are designed with drainage slots to prevent moisture buildup between the wrap and tank.

Do I need to replace mounting brackets when replacing air tanks?

Not necessarily. If your existing brackets are in good condition without cracks, excessive rust, or bent components, they can typically be reused. However, it's recommended to replace the rubber isolators and mounting bolts when installing new tanks. These wear items are inexpensive and help prevent vibration damage. If upgrading from steel to aluminum tanks, verify that your current brackets can handle the slightly different weight distribution, though most are universal.
