Frequently Asked Questions About International 9300/9370 Bug Shields

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

Most bug shields for International 9300/9370 trucks are designed to fit models from 1987 through 2007. However, there are slight variations between early models (1987-1999) and later models (2000-2007) due to hood design changes. Always verify the specific year range listed for each bug shield, as some are universal while others are year-specific. If your truck has aftermarket modifications to the hood or grille, measure the mounting area to ensure proper fitment.

What material options are available, and which holds up best against rocks and road debris?

Bug shields for these trucks typically come in three materials: acrylic plastic, ABS plastic, and stainless steel. Acrylic shields offer good clarity and UV resistance but may crack under heavy impact. ABS plastic shields are more impact-resistant and typically last 5-7 years with proper care. Stainless steel shields provide the ultimate durability and can handle severe conditions, though they're heavier and more expensive. For drivers regularly encountering gravel roads or construction zones, ABS or stainless steel options offer the best long-term value.

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

Installation typically takes 30-45 minutes and requires basic hand tools including a drill with metal bits, socket wrenches, and a measuring tape. Most bug shields mount using existing hood holes or require drilling 4-6 new holes in the hood's underside lip. The main challenge reported by customers is achieving proper alignment to prevent wind noise at highway speeds. Having a second person assist with positioning while marking drill holes significantly improves the installation outcome.

Are there different styles available, and do they affect airflow or fuel economy?

Bug shields come in three main styles: wrap-around (full coverage), center-mount (partial coverage), and low-profile designs. Wrap-around shields offer maximum protection but may create more wind resistance. Center-mount shields protect the grille area while maintaining better aerodynamics. Low-profile shields minimize wind resistance but offer less coverage. Most drivers report negligible fuel economy impact (less than 1 mpg difference), though wrap-around styles may produce more wind noise above 65 mph.

What finish options work best for different climates and how do I maintain them?

Chrome-finished shields look sharp but require regular polishing to prevent pitting in salt-heavy regions. Powder-coated black shields hide minor scratches better and need less maintenance in harsh climates. Polished stainless shields offer the best corrosion resistance for coastal areas or winter road salt exposure. For maintenance, wash with mild soap monthly and apply automotive wax to acrylic shields quarterly. Avoid harsh chemicals or abrasive cleaners that can cloud acrylic or damage powder coating.
