Frequently Asked Questions About International 9300/9370 Mud Flaps

What years and models of International 9300/9370 trucks are these mud flaps compatible with?

Our mud flaps are designed to fit International 9300 models from 1987-2003 and International 9370 models from 1992-2003. However, compatibility can vary based on your specific truck configuration, including sleeper vs. day cab models and aftermarket modifications. We recommend checking your truck's exact measurements or contacting our support team with your VIN for verification before ordering.

What's the difference between rubber and stainless steel backed mud flaps, and which should I choose?

Rubber mud flaps are more economical, flexible in cold weather, and absorb impact well, making them ideal for standard highway use. Stainless steel backed mud flaps offer superior durability, maintain their shape better, and provide a polished professional appearance, though they cost more upfront. For heavy-duty applications or if you want maximum longevity and appearance, choose stainless steel backed. For budget-conscious buyers or moderate use, standard rubber performs well.

Do I need to drill new holes to install these mud flaps, and what tools are required?

Most of our International 9300/9370 mud flaps use existing mounting holes and brackets, requiring no drilling for standard installations. You'll typically need basic hand tools including a socket set, wrenches, and possibly a drill if your truck has non-standard brackets. Installation usually takes 30-45 minutes per set. Some anti-sail brackets may require additional mounting hardware, which is included with those specific models.

What size mud flaps do I need for my International 9300/9370, and do you offer custom sizing?

Standard sizes for these models are 24" x 30" for most applications, though 24" x 36" is common for trucks with larger tires or those requiring extra coverage for DOT compliance. Measure from your mounting point to ensure proper ground clearance (typically 6-8 inches). We offer custom cutting services for non-standard applications - just specify your exact dimensions when ordering or contact us for assistance.

How do anti-sail or anti-spray mud flaps differ from standard ones, and are they worth the extra cost?

Anti-sail mud flaps feature weighted bottoms or special brackets that prevent the flaps from flying up at highway speeds, reducing spray and improving protection. They're especially valuable for trucks frequently driving in wet conditions or at sustained highway speeds above 65 mph. While they cost 20-30% more than standard flaps, drivers report significantly less road spray hitting their trailers and better overall performance in windy conditions.
