Frequently Asked Questions About International 9300/9370 Door & Cab Side Accessories

What model years do these door and cab accessories fit, and are there any fitment differences I should know about?

Our International 9300/9370 door and cab accessories are designed to fit models from 1987 through 2004. However, there are some important distinctions: accessories for the 9300 series (1987-2004) and 9370 series (1995-2004) may have slight differences in mounting points and dimensions. Always verify your specific truck's VIN and production year before ordering. For trucks with aftermarket modifications or non-standard cabs, we recommend calling our technical support team at 1-888-875-7787 for fitment verification.

How difficult is it to install door handles and window regulators on these trucks, and what tools will I need?

Most door handles and window regulators can be installed in 1-2 hours with basic hand tools. You'll typically need a socket set (10mm-13mm), Phillips and flathead screwdrivers, and a door panel removal tool. The biggest challenge customers face is accessing the inner door panel clips without breaking them. We recommend having replacement door panel clips on hand before starting. Window regulator installations require removing the door panel completely and may need two people to properly align the glass during reassembly.

What's the difference between chrome, stainless steel, and plastic door accessories, and which holds up better?

Stainless steel accessories offer the best long-term durability and corrosion resistance, especially in harsh weather conditions or areas using road salt. Chrome-plated parts provide an excellent mirror finish but may show pitting or rust after 3-5 years of exposure. Plastic components are the most affordable but can become brittle and fade over time, particularly the door handle bezels and mirror housings. For maximum longevity, we recommend stainless steel for exterior applications and chrome for protected areas like interior door handles.

Are aftermarket door seals and weatherstripping as good as OEM, and how can I tell if mine need replacing?

Quality aftermarket door seals can match or exceed OEM performance when properly installed. Look for EPDM rubber construction with a dense foam core. Signs you need replacement include water leaks during rain or washing, excessive wind noise above 55 mph, visible gaps when the door is closed, or rubber that's cracked, torn, or permanently compressed. Poor door seals can also cause premature wear on door hinges and latches due to improper door alignment.

What cab and sleeper accessories are available for day cab versus sleeper configurations?

Day cabs and sleeper configurations require different accessories due to their distinct designs. Day cabs typically use standard grab handles, sun visors, and cab extenders. Sleeper models need longer grab handles, sleeper-specific window vents, and additional weatherstripping around the sleeper boot area. Both configurations share common items like door handles, mirrors, and step plates. When ordering cab fairings or extenders, you must specify whether you have a day cab or sleeper, as the mounting brackets and dimensions differ significantly.
