Frequently Asked Questions About International 9300/9370 Cab & Related

What years and models are compatible with International 9300/9370 cab parts?

Most cab parts for the International 9300/9370 series are compatible with models from 1987 through 2003. However, there are some variations between early models (1987-1994) and later models (1995-2003), particularly in door handles, mirror mounting brackets, and interior trim pieces. Always verify your specific VIN and production year when ordering electrical components or hood hinges, as these can vary even within the same model year.

Are aftermarket cab parts as durable as OEM for the 9300/9370 series?

Quality aftermarket cab parts can match or exceed OEM durability when sourced from reputable manufacturers. Look for parts made from 16-gauge steel or thicker for structural components, and ensure door seals are made from EPDM rubber rather than generic foam. Chrome and stainless steel trim pieces should have a minimum thickness of 2mm to resist vibration cracking. Avoid painted steel mirrors under $50, as these typically use thin metal that vibrates excessively at highway speeds.

What are the most common installation challenges for 9300/9370 cab accessories?

The three most common installation issues are: misaligned door hinges requiring shim adjustments (especially on trucks over 500,000 miles), rusted or stripped mounting holes that need re-tapping or welding, and electrical connectors that don't match between model years. Many customers report needing to drill new holes for aftermarket mirror arms due to slight spacing differences. We recommend having a drill with metal bits, thread tap set, and electrical butt connectors on hand before starting any cab part installation.

What finish options hold up best for exterior cab parts on these trucks?

For maximum durability, choose 304 stainless steel for grab handles, mirror brackets, and trim pieces. Chrome-plated parts look excellent initially but typically show pitting within 2-3 years in salt belt states. Powder-coated aluminum parts offer good corrosion resistance at a lower price point than stainless. For painted parts, look for those with e-coat primer underneath, as standard primer-only parts often rust through within 18 months of installation.

Do I need special tools or modifications to install cab glass and weather stripping?

Installing windshields requires professional-grade urethane adhesive and primer, plus a cutting tool to remove old urethane. Door glass typically needs only basic hand tools, but having plastic trim removal tools prevents damage to paint and chrome. Weather stripping installation requires weatherstrip adhesive (not regular glue) and a heat gun or hair dryer to make the rubber pliable in cold weather. Pre-1995 models may require trimming door seals by up to 2 inches due to production variations.
