Frequently Asked Questions About International 9300/9370 Sleeper Roof Accessories

What year models of International 9300 and 9370 trucks do these roof accessories fit?

Our sleeper roof accessories are designed to fit International 9300 models from 1987-2004 and International 9370 models from 1990-2003. However, compatibility can vary based on whether your truck has a flat top or raised roof sleeper configuration. We recommend checking your specific sleeper measurements or contacting our team with your VIN to ensure proper fitment before ordering.

How difficult is it to install these roof fairings and accessories myself?

Most roof accessories can be installed with basic tools and mechanical knowledge in 2-4 hours. The installation typically requires drilling mounting holes, so you'll need a quality drill with metal bits, measuring tape, and a helper for positioning larger pieces. Many accessories come with templates or detailed instructions. Common challenges include proper alignment and sealing around mounting points to prevent leaks. Professional installation is recommended for full roof fairings or if you're uncomfortable drilling into your sleeper.

What materials are these roof accessories made from, and how do they hold up to weather?

The majority of our International 9300/9370 roof accessories are manufactured from either fiberglass or ABS plastic. Fiberglass options offer superior durability and UV resistance but are heavier and more expensive. ABS plastic accessories are lighter and more affordable while still providing good weather resistance. Both materials are designed to withstand highway speeds and extreme weather conditions. For maximum longevity, we recommend periodic cleaning and applying UV protectant to prevent fading.

Do these roof accessories come in different finishes, and can they be painted?

Most roof accessories come in either gel-coated white or unpainted primer finish. The gel-coated options are ready to install but limited in color choices. Unpainted accessories offer the flexibility to match your truck's exact color but require proper prep work and automotive paint. Both fiberglass and ABS accessories can be painted using standard automotive painting procedures. Some accessories are also available in chrome-look ABS or polished stainless steel for those wanting a bright finish.

Will adding roof accessories affect my fuel economy or increase wind noise?

Properly designed roof fairings and accessories can actually improve fuel economy by reducing aerodynamic drag, with some drivers reporting 3-5% better mileage. However, incorrectly sized or poorly installed accessories may increase wind resistance and noise. The key is selecting accessories that create smooth airflow over your sleeper and trailer gap. Roof-mounted accessories like horns or lights typically have minimal impact on fuel economy but may create slight wind noise at highway speeds if not properly secured.
