Frequently Asked Questions About International 9300/9370 Mirrors & Accessories

Will these mirrors fit my specific International 9300 or 9370 model year?

Most aftermarket mirrors for International 9300/9370 trucks are designed to fit model years 1987-2007. However, there can be variations between early and late production years. The 9300 typically covers 1987-2004 models, while the 9370 runs from 2002-2007. Always verify the mounting bracket style on your truck - pre-2000 models often use different mounting configurations than 2000+ models. When ordering, have your VIN ready to confirm compatibility, especially if your truck is a 1999-2002 model year where design transitions occurred.

What's the difference between heated and non-heated mirror options, and is the upgrade worth it?

Heated mirrors include internal heating elements that prevent ice and fog buildup, requiring a 12-volt power connection to your existing mirror wiring harness. Non-heated mirrors are standard manual units without this feature. The heated upgrade typically adds $40-80 per mirror but is highly recommended for drivers operating in cold climates or dealing with frequent temperature changes. Installation requires connecting two additional wires, which most International 9300/9370 trucks already have pre-wired in the door panels from the factory.

Can I install these mirrors myself, or do I need professional help?

Mirror replacement on International 9300/9370 trucks is generally a DIY-friendly job that takes 30-45 minutes per side. You'll need basic tools: a socket set (typically 13mm and 15mm), Phillips and flathead screwdrivers, and possibly a door panel removal tool. The most challenging part is accessing the mounting bolts through the door panel - some models require partial door panel removal. Electric mirrors require connecting 3-5 wires using the existing harness connectors. If your truck has never had electric mirrors, professional installation may be needed to run new wiring.

What mirror styles and finishes are available, and which hold up best?

Common options include chrome, stainless steel, and black powder-coated finishes. Chrome provides the classic look but requires regular polishing to prevent pitting and rust, especially in areas using road salt. Stainless steel offers excellent durability with less maintenance but costs 20-30% more. Black powder-coated mirrors are increasingly popular for their durability and modern appearance, showing fewer water spots and requiring minimal maintenance. For mirror heads, you can choose between standard flat glass, convex, or combination styles with integrated spot mirrors.

Why are some mirror assemblies so much cheaper than others - what's the quality difference?

Price variations typically reflect differences in materials and construction quality. Premium mirrors ($150-300 each) feature metal housings, automotive-grade motors, OEM-spec wiring harnesses, and glass with proper anti-glare backing. Budget options ($50-100 each) often use plastic housings that can crack in extreme temperatures, lower-quality motors that may fail within 1-2 years, and thinner mirror glass prone to vibration. Mid-range options ($100-150 each) usually offer the best value, with reinforced polymer housings and decent motors that last 3-5 years under normal use.
