International Quarter Fenders

Frequently Asked Questions About International Quarter Fenders

What are quarter fenders and what part of the truck do they cover?

Quarter fenders are the curved fender panels that mount over the rear wheels of your International truck, typically behind the cab or on the frame near the drive axles. They help shield the truck body, other drivers, and the road from mud, water, and debris thrown up by the tires.

Will these quarter fenders fit my specific International model and wheelbase?

Fender fitment depends on your specific International model, cab configuration, and axle setup, since mounting points and fender radius can vary between trucks. Always check the listed model compatibility and measurements on each product page, and compare them to your truck's specs before ordering to avoid return shipping hassles.

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

International quarter fenders are commonly available in steel, aluminum, or heavy-duty poly/composite materials. Steel offers strength and a traditional look but can be prone to rust if the finish is damaged, aluminum resists corrosion and is lighter, and poly fenders are flexible and resistant to cracking or denting from road debris. Your choice often comes down to the balance of durability, weight, and appearance you want.

What finish options are available, and do I need to paint or treat them after installation?

Fenders are typically offered in raw/unpainted steel, painted, powder-coated, or polished aluminum finishes. Raw steel fenders will need to be primed and painted to prevent rust, while powder-coated or polished finishes are ready to install as-is. If you want a factory color match, plan on paint work after purchase unless the listing specifies a pre-matched finish.

What does installation typically involve, and can I install these myself?

Most quarter fenders mount using brackets, hangers, or existing bolt holes on the frame or fender supports, so many truck owners are able to install them with basic hand tools in a home shop or bay. That said, proper alignment matters for tire clearance and stability, so if your truck requires drilling, welding, or custom bracket fabrication, it's a good idea to have a qualified technician handle the install or at least double-check your work.
