Frequently Asked Questions About International 9300/9370 Air Tanks, Wraps & Mounts

What size air tanks fit the International 9300 and 9370, and are they interchangeable between model years?

Most International 9300 and 9370 models from 1987-2007 use standard 11" x 37" or 13" x 31" aluminum air tanks. The mounting brackets are generally compatible across these years, but slight variations exist between pre-2000 and post-2000 models. We recommend measuring your existing tank dimensions and bracket spacing before ordering. Tank ports typically come in 1/4" or 3/8" NPT configurations, so verify your airline fitting requirements.

How difficult is it to install replacement air tank mounting brackets, and what tools are required?

Installation typically takes 2-3 hours per side with basic hand tools. You'll need a socket set (typically 9/16" and 3/4"), wrenches, and a torque wrench. The main challenges include safely supporting the tank during bracket removal and ensuring proper alignment. Many customers report rust on original bolts, so having penetrating oil and replacement Grade 8 bolts (usually 3/8"-16 x 1.5") on hand is recommended. Professional installation runs $150-300 if you prefer not to DIY.

What's the difference between chrome, stainless steel, and polished aluminum tank wraps?

Chrome-plated steel wraps offer the highest shine but require regular polishing to prevent rust, especially in salt-belt states. Stainless steel wraps (usually 304-grade) resist corrosion better and maintain their appearance with minimal maintenance, though they're slightly less mirror-like than chrome. Polished aluminum wraps are the lightest option and won't rust, but they can oxidize over time and may show water spots more readily. Price-wise, expect chrome to be most affordable, stainless steel mid-range, and polished aluminum typically the premium option.

Will aftermarket air tanks affect my truck's air system performance or DOT compliance?

Quality aftermarket tanks meeting SAE J10 specifications perform identically to OEM units and maintain DOT compliance. All tanks we carry are certified for 150 PSI working pressure with proper safety factors. The key is ensuring your replacement tank matches or exceeds your original tank's volume (measured in cubic inches) to maintain proper air reserve for braking. Most International 9300/9370 models require minimum 3,450 cubic inches total air capacity for compliance.

How do I know if I need new mounting straps versus just the decorative wrap?

Inspect your existing straps for cracks, excessive rust, or deformation where they contact the tank. If straps show pitting deeper than 1/16" or any cracks at the bolt holes, replacement is necessary for safety. Decorative wraps can be added over sound straps purely for appearance. Note that tank straps are typically 3" or 4" wide - measure yours before ordering. If your straps are painted and structurally sound, you can install wrap-around covers without removing the tank, saving significant installation time.
