Frequently Asked Questions About International 9900/i/ix Mirrors & Accessories

What years and models are these mirrors compatible with?

Our International 9900 series mirrors are designed to fit the 9900i and 9900ix models from 1996 through 2016. The standard 9900 (non-i version) uses the same mirror mounting pattern, so these will also work on those trucks. However, always verify your specific truck's mirror arm configuration before ordering, as some custom spec trucks may have variations. If you're unsure about fitment, check the mounting bolt pattern on your existing mirrors - standard spacing is typically 4.5 inches center-to-center.

Are these mirrors heated and motorized, or manual only?

We carry both heated/motorized and manual mirror options for the 9900 series. Heated mirrors require a 12V power connection and are highly recommended for drivers in cold climates to prevent ice buildup. Motorized mirrors allow adjustment from inside the cab and typically include the wiring harness. Manual mirrors are more affordable and have fewer potential failure points but require physical adjustment. When replacing powered mirrors with manual ones, you'll need to cap off the electrical connections properly.

What's the difference between chrome, stainless steel, and black mirror options?

Chrome mirrors offer the classic shiny appearance but require regular polishing to maintain their finish and may show pitting over time in harsh conditions. Stainless steel mirrors provide excellent corrosion resistance with less maintenance than chrome, though they have a slightly different shine. Black mirrors are typically powder-coated and hide dirt well but may show scratches more easily. For longevity in salt-heavy regions, stainless steel is your best bet, while chrome gives the showiest appearance when well-maintained.

How difficult is the installation, and what tools do I need?

Mirror installation typically takes 30-60 minutes per side for someone with basic mechanical skills. You'll need a socket set (usually 13mm-19mm), potentially a drill if mounting new brackets, and electrical connectors if installing powered mirrors. The most common challenge is aligning the mirrors properly for optimal visibility. We recommend having a helper to hold the mirror in position while you tighten the mounting bolts. For powered mirrors, basic electrical knowledge is helpful for connecting the heating and motor functions to your existing wiring.

Will aftermarket mirrors affect my visibility compared to OEM?

Quality aftermarket mirrors can match or exceed OEM visibility when properly selected and adjusted. The key is choosing mirrors with the correct convex rating for your application - typically 8-inch convex for the passenger side and flat or slight convex for the driver side. Some drivers report that certain aftermarket options actually provide better blind spot coverage than factory mirrors. Make sure to select mirrors that meet FMVSS 111 standards for commercial vehicles, and take time during installation to adjust them properly for your specific seating position.
