Frequently Asked Questions About International 9300/9370 Roof Trim

Will this roof trim fit my specific International 9300 or 9370 model year?

Most aftermarket roof trim for International 9300/9370 trucks fits models from 1987 through 2007. However, there are slight variations between early models (1987-1999) and later models (2000-2007), particularly in mounting hole patterns and overall length. Always verify the exact measurements and compare them to your truck's existing trim or mounting points. If you're unsure, measure the distance between your mounting holes and the overall length needed before ordering.

What material options are available, and which holds up best against weather and UV exposure?

Roof trim typically comes in three materials: chrome-plated steel, stainless steel, and chrome-plated ABS plastic. Stainless steel offers the best long-term durability and won't rust or pit, making it ideal for trucks operating in harsh weather conditions. Chrome-plated steel provides a brilliant shine but may eventually show rust spots if the chrome gets chipped. ABS plastic trim is the most affordable and lightweight option but can fade or become brittle after prolonged sun exposure. For maximum longevity, we recommend 304-grade stainless steel.

Do I need to drill new holes for installation, or will it use existing mounting points?

Most quality roof trim pieces are designed to use your truck's existing factory mounting holes. However, some trucks may have had their original trim removed and holes filled during previous bodywork. In these cases, you'll need to drill new holes following the trim's pre-marked spacing. The installation typically requires 6-8 mounting points along the roofline. Always test-fit the trim before drilling to ensure proper alignment with your cab's contours.

What's the difference between the various styles like standard, wide, and lighted roof trim?

Standard roof trim typically measures 2-3 inches in height and provides a clean, classic look. Wide trim ranges from 4-6 inches and creates a more prominent visual statement. Lighted roof trim includes either built-in LED marker lights or pre-drilled holes for adding your own lights, which may require additional wiring to your truck's clearance light circuit. Consider your state's regulations regarding additional lighting before choosing lighted trim, as some states have restrictions on the number and placement of marker lights.

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

Installation is generally straightforward and takes 1-2 hours for someone with basic mechanical skills. You'll need a drill with metal bits (if drilling new holes), a rivet gun or appropriate fasteners, masking tape for alignment marking, and possibly silicone sealant for weatherproofing. The most challenging aspect is ensuring the trim sits perfectly straight along the roofline. We recommend having a helper to hold the trim in position while you mark and secure the mounting points. Start from the center and work outward to prevent warping or misalignment.
