Frequently Asked Questions About International 4700-4900 Air Tanks, Wraps & Mounting

Will these air tanks fit my specific International 4700 or 4900 model year?

Our air tanks are designed to fit International 4700 and 4900 series trucks from 1989 through 2001. However, there can be variations based on your truck's specific configuration, wheelbase, and whether it has DT466 or DT530 engines. We recommend checking your existing tank dimensions or contacting us with your VIN to ensure proper fitment. Most standard cab configurations use either 25-inch or 19-inch diameter tanks.

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 and can handle higher impact without denting. For trucks operating in salt-heavy regions or those prioritizing weight savings, aluminum is recommended. Steel tanks work well for budget-conscious operators in drier climates.

Do I need special tools or brackets to install these air tanks?

Installation typically requires basic hand tools, including wrenches, sockets, and air line fittings. Most replacement tanks use your existing mounting brackets, but some applications may require new straps or brackets, especially when upgrading tank sizes. Installation usually takes 1-2 hours per tank. Always ensure proper air line routing and use thread sealant on all fittings to prevent leaks.

What air tank wrap options are available, and are they worth it?

We offer polished stainless steel wraps, chrome-plated wraps, and painted wraps in various colors. Wraps not only enhance appearance but also provide additional protection against road debris and corrosion. Stainless steel wraps are most popular due to their durability and maintenance-free shine. They typically add 3-5 years to tank life and are especially valuable for show trucks or vehicles where appearance matters.

How do I know when my air tanks need replacement?

Replace air tanks immediately if you notice visible rust holes, excessive corrosion around fittings, moisture in air lines despite regular draining, or if the tank fails to hold pressure. As a preventive measure, inspect tanks annually for pitting, especially at the bottom where moisture collects. Most steel tanks last 5-7 years, while aluminum tanks can last 10-15 years with proper maintenance.
