International DuraStar Full Radius Fenders

Frequently Asked Questions About International DuraStar Full Radius Fenders

What are full radius fenders and how do they differ from other fender styles?

Full radius fenders form a complete, continuous half-circle arc over the wheel, matching the natural curve of the tire from front to back. This differs from quarter or half fenders, which only cover a portion of the wheel. Full radius fenders are the style most commonly found as factory equipment on International DuraStar trucks, so they are a popular choice for owners looking to replace a damaged or worn original fender with a similar look.

Will these fenders fit my specific DuraStar model year?

International made changes to fender mounting brackets and dimensions across different DuraStar production years, so fit can vary. Always check the listed year range and cab configuration for each fender before ordering, and compare the bracket style and mounting hole pattern to your existing setup. If you are unsure, having your VIN or truck year on hand when contacting us can help confirm compatibility.

What materials are these fenders made from, and how do they hold up?

Full radius fenders for the DuraStar are typically available in materials such as steel, aluminum, or poly/composite blends. Steel offers durability and a factory-matching look but is heavier and can be prone to rust if the finish is compromised. Aluminum resists corrosion and is lighter, while poly composite fenders are lightweight and resistant to dents and rust, though they may flex more under impact. Your choice often depends on whether you prioritize weight savings, corrosion resistance, or a traditional appearance.

Do these fenders come primed, painted, or finished, or will I need to paint them myself?

Most full radius fenders are sold unpainted or in a primed finish, giving you the flexibility to match your truck's paint color. Some material options, like polished aluminum, may come with a natural finish that does not require paint. Be sure to check the product description for finish details before ordering if color matching is important to you.

What does installation typically involve, and can I do it myself?

Installation generally involves removing the damaged or worn fender from its mounting brackets and bolting the new fender into place using the existing hardware or new mounting brackets, depending on condition. Many truck owners with basic mechanical experience and common hand tools are able to complete this job in a home garage or shop setting. If your brackets are damaged or heavily rusted, you may need to replace those as well to ensure a secure, properly aligned fit.
