Frequently Asked Questions About International RH Mud Flaps
Will these mud flaps fit my specific International truck model and year?
International RH mud flaps are designed for right-hand (passenger side) fitment on most International trucks including ProStar, LoneStar, 9900i, and PayStar models from 2008 to present. However, fitment can vary based on your specific configuration, especially if you have aftermarket modifications or custom fender setups. We recommend checking your current mud flap bracket spacing and comparing it to the product specifications, or contact our support team with your OEM for exact fitment verification.
What's the difference between rubber and stainless steel backed mud flaps?
Rubber mud flaps are the most economical option, offering good protection and flexibility in extreme temperatures. They typically last 2-3 years with regular use. Stainless steel backed mud flaps feature a polished or brushed metal plate bonded to heavy-duty rubber, providing superior durability, a premium appearance, and 5+ years of service life. The metal backing prevents the flap from curling or bending at highway speeds, making them ideal for long-haul applications.
Do I need special tools or brackets to install these mud flaps?
Most International RH mud flaps use the existing factory mounting holes and brackets, requiring only basic hand tools like a socket set and drill (if new holes are needed). Installation typically takes 15-30 minutes per side. Some aftermarket or custom setups may require universal mounting brackets, which are sold separately. Anti-sail brackets are recommended for quarter fender applications to prevent wind lift at highway speeds.
How do I choose the correct size mud flap for my truck?
Standard International RH mud flaps come in 24" x 30" or 24" x 36" sizes. The 30" length works best for highway tractors and day cabs, while 36" flaps are recommended for vocational trucks or those frequently driving on unpaved roads. Measure from your mounting point to approximately 6-8 inches from the ground for optimal coverage. Quarter fender models typically use 24" x 24" flaps.
Are these mud flaps DOT compliant and will they work with my state's regulations?
Yes, all our International RH mud flaps meet or exceed DOT requirements for spray suppression. They extend to within 8 inches of the ground when properly installed, satisfying federal regulations. Some states have specific requirements for reflective tape or anti-spray designs, which are available as options. Always verify your state's specific commercial vehicle requirements, as some jurisdictions mandate full-width coverage or specific materials for certain applications.
