Frequently Asked Questions About International WorkStar Air Tanks, Wraps & Mounting

Will these air tanks fit my specific International WorkStar model year?

Our air tanks are designed to fit International WorkStar models from 2008-2017. However, fitment can vary based on your truck's specific configuration, wheelbase, and existing mounting brackets. We recommend checking your current tank dimensions and mounting hole patterns before ordering. If you're unsure, contact our support team with your VIN number and we can verify compatibility for your exact truck.

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

Aluminum tanks are lighter weight (typically 40-50% lighter than steel), resist corrosion better, and won't rust - making them ideal for trucks operating in wet or salty conditions. Steel tanks are more affordable and extremely durable against impacts, but require regular inspection for rust. Most WorkStar owners choose aluminum for weight savings and longevity, especially if they're in snow belt states or coastal areas.

Can I install these air tanks myself, or do I need a professional?

Installation typically takes 2-4 hours for someone with basic mechanical skills. You'll need standard hand tools, air line fittings, and possibly new mounting brackets depending on your setup. The most challenging part is usually accessing the mounting points and properly routing air lines. Many customers successfully DIY the installation, but if you're not comfortable working with air brake systems, we recommend professional installation for safety reasons.

Do the tank wraps and heat shields really make a difference in cold weather?

Yes, insulated tank wraps significantly reduce moisture freezing issues in temperatures below 32?F. They help maintain more consistent air temperature, reducing condensation that can freeze in air lines and valves. Customers in northern states report 60-70% fewer freeze-up issues after installing quality tank wraps. For best results, combine wraps with regular draining of your tanks and consider adding an air dryer system.

What size air tank do I need for my WorkStar?

Most WorkStar trucks come standard with either 20-gallon or 25-gallon tanks, depending on the model and application. Heavy-duty vocational trucks often use dual 25-gallon setups. Check your door jamb sticker or existing tank stampings for OEM specifications. Going larger than stock can provide more air reserve for accessories, but ensure your compressor can handle the increased volume and that you have adequate mounting space.
