Frequently Asked Questions About International IH Cabover Air Tanks-Wraps-Mount

What years and models of International IH Cabovers are these air tanks compatible with?

Our air tanks and mounting systems are designed to fit International IH Cabover models from the 1970s through the early 2000s, including the 9670, 9700, and Eagle series. The most common fitments are for 1980-2000 models. However, mounting bracket configurations can vary between specific years and whether you have a set-forward or set-back front axle. We recommend checking your VIN or calling our technical support team at 1-888-875-7787 with your specific model year for exact fitment confirmation.

Are these aluminum or steel air tanks, and which is better for my application?

We carry both aluminum and steel air tank options. Aluminum tanks are lighter weight (typically 40-50% lighter than steel), resist corrosion better, and are ideal for weight-conscious operators. Steel tanks are more economical, extremely durable, and better suited for harsh environments where impact resistance is crucial. Most over-the-road drivers prefer aluminum for weight savings, while vocational applications often choose steel for durability. All our tanks meet DOT specifications and include proper certification stamps.

Do the air tank mounting kits include all necessary hardware, or will I need additional parts?

Our complete mounting kits include heavy-duty brackets, grade 8 bolts, lock washers, and rubber isolators. However, you may need to purchase air line fittings separately depending on your existing setup. Most installations require 1/2 inch NPT fittings for the supply and signal lines. If you're replacing factory tanks, you can typically reuse your existing fittings and valves. For custom installations or relocations, budget for additional air line, fittings, and possibly new gladhand connections.

What's involved in the installation process, and can I do it myself?

Installation typically takes 2-4 hours for experienced mechanics and requires basic air system knowledge. You'll need to safely depressurize the system, remove old tanks, mount new brackets (some drilling may be required), install tanks with proper clearance, and reconnect all air lines while checking for leaks. Critical steps include maintaining proper tank angles for moisture drainage and ensuring brackets are torqued to specification (typically 85-100 ft-lbs). While DIY is possible, we recommend professional installation if you're unfamiliar with air brake systems to ensure DOT compliance and safety.

What size air tanks do I need, and can I upgrade from my factory size?

Factory International IH Cabovers typically came with either single 20-gallon or dual 16-gallon tank configurations. You can upgrade tank size as long as you maintain proper frame clearance and weight distribution. Common upgrades include going from single to dual tank setups or increasing to 25-gallon tanks for better air capacity. Larger tanks provide more reserve capacity and reduce compressor cycling, but ensure your frame rails can accommodate the larger diameter and your compressor can handle the increased volume. Most frames can accept tanks up to 25 gallons without modification.
