Frequently Asked Questions About International ProStar Mud Flaps

What are the exact year and model compatibility for ProStar mud flaps?

Our International ProStar mud flaps are designed to fit model years 2008-2017. These mud flaps are compatible with both day cab and sleeper configurations. However, trucks with aftermarket modifications such as lowered suspensions or custom fender extensions may require additional brackets or adjustments. We recommend checking your specific VIN with our customer service team if you have a 2017 or newer model, as International made some design changes mid-year that can affect fitment.

What materials are available and which holds up best in harsh conditions?

We offer ProStar mud flaps in three primary materials: heavy-duty rubber, anti-sail polymer, and stainless steel backed options. The heavy-duty rubber flaps (typically 3/8" to 1/2" thick) provide excellent durability for standard highway use and resist cracking in temperatures from -40F to 180F. For drivers dealing with extreme weather or heavy debris, our anti-sail polymer flaps feature reinforced edges and weighted bottoms to prevent flapping at highway speeds. The stainless steel backed versions offer maximum protection and longevity but add approximately 8-10 pounds per flap.

Do I need special tools or brackets for installation?

Most ProStar mud flap installations require basic hand tools including a socket set, drill with metal bits, and measuring tape. The standard mounting brackets that come with our mud flaps fit directly into existing factory mounting points on 2008-2016 models. For 2017 models, you may need our adapter bracket kit (sold separately). Installation typically takes 30-45 minutes per side. Some customers report that accessing the upper mounting bolts is easier with the wheels turned, and having a second person helps align the brackets during installation.

What sizes and styles are available for different ProStar configurations?

Standard ProStar mud flaps come in 24" x 30" for most applications, with 24" x 36" options for trucks with lift kits or larger tires. We offer plain black, chrome weight bottom, and custom logo options. Quarter fender flaps are available in 16" x 24" for additional side protection. Customers with wide-base single tires should consider our 30" wide flaps to ensure complete coverage. Anti-spray styles feature horizontal grooves that reduce water spray by up to 70% compared to smooth surface designs.

How do I prevent mud flaps from breaking off or getting damaged during backing?

The most common cause of mud flap damage is catching them while backing up to docks or over curbs. We recommend installing adjustable anti-sail brackets that allow 15-20 degrees of swing to prevent stress breaks. Position your mud flaps with 6-8 inches of ground clearance when the truck is loaded. Many drivers also add reflective tape to the bottom edge for better visibility. For frequent dock work, consider our spring-loaded hangers that allow the flaps to fold forward when contacted, returning to position automatically.
