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

What size air tanks are compatible with my International ProStar, and how do I determine the correct fitment?

International ProStar models typically accommodate air tanks ranging from 11" to 13" in diameter, with lengths varying from 24" to 30". To determine the correct size for your truck, check your existing tank dimensions or reference your VIN-specific build sheet. Most 2008-2017 ProStar models use standard 11" x 24" or 11" x 30" aluminum tanks. Always verify mounting bracket spacing before ordering, as some model years have different frame rail configurations.

Are the aluminum air tanks worth the extra cost compared to steel tanks?

Aluminum air tanks offer significant advantages that justify the higher initial cost. They weigh approximately 50% less than steel tanks, improving fuel economy and payload capacity. Aluminum tanks also resist corrosion better in harsh weather conditions and road salt exposure. While steel tanks may need replacement every 5-7 years due to rust, quality aluminum tanks can last the lifetime of your truck with proper maintenance. The weight savings alone can pay for the price difference within the first year of operation.

Can I install these air tank mounting brackets myself, or do I need professional installation?

Air tank installation is a moderate difficulty job that experienced mechanics can complete in 2-3 hours. You'll need basic hand tools, proper jack stands, and ideally an air impact wrench. The most challenging aspects are safely supporting the tank during installation and ensuring proper air line routing. Critical safety note: always depressurize the system completely before beginning work and use new DOT-approved air fittings. If you're uncomfortable working with air brake systems, professional installation is recommended for safety and DOT compliance.

Do the polished stainless steel tank wraps require special maintenance to keep their shine?

Polished stainless steel wraps maintain their appearance with minimal effort compared to chrome. For best results, clean them every 2-3 weeks using a quality stainless steel cleaner and microfiber cloth. Avoid abrasive cleaners or steel wool which can scratch the finish. In winter conditions with heavy road salt, rinse the wraps weekly to prevent salt buildup. The wraps feature a 16-gauge construction that resists denting and maintains its shape better than thinner aftermarket options.

Will aftermarket air tanks affect my warranty or DOT compliance?

Quality aftermarket air tanks that meet DOT specifications will not void your warranty when properly installed. Look for tanks stamped with DOT certification numbers and rated for your system's operating pressure (typically 150 PSI for ProStar models). Keep all documentation and certification papers with your vehicle records for inspections. Some states require annual air tank inspections regardless of age, so ensure any replacement tank has proper date coding and certification markings clearly visible.
