Frequently Asked Questions About International IH Cabover Front Fenders & Acc.

What year models and series do these fenders fit?

Our International IH cabover fenders are designed to fit various models including the Transtar CO-4000 series (1974-1980), CO-9670 (1973-1982), and Paystar CO-5000 series. Due to slight variations between model years, we recommend verifying your specific VIN and model number before ordering. If you're unsure about compatibility, our customer service team can help confirm fitment with your truck's details.

Are these fenders made from fiberglass or steel, and which is better for my application?

We offer both fiberglass and steel options. Fiberglass fenders are lighter weight (reducing front axle load), rust-resistant, and easier to repair minor damage. Steel fenders provide superior durability for heavy-duty applications and better resistance to impact damage. Most owner-operators choose fiberglass for weight savings and corrosion resistance, while fleet operators often prefer steel for longevity in harsh conditions.

Do I need special brackets or hardware for installation?

Installation typically requires the existing mounting brackets from your original fenders. New mounting hardware kits are available separately if your brackets are damaged or missing. You'll need basic hand tools, and we recommend having a helper for alignment. Most installations take 2-4 hours per side. Some customers report needing minor drilling or modification of mounting holes on certain model years.

What finish options are available, and can they be painted?

Our fenders come in either gel-coat white (fiberglass) or primer finish (steel), both ready for painting. The gel-coat finish can be used as-is or painted to match your truck. Steel fenders must be painted before use to prevent rust. Both materials accept standard automotive paints well. Many customers choose to have them professionally painted before installation for best results.

Will aftermarket fenders affect my truck's weight distribution or handling?

Fiberglass fenders typically weigh 40-60% less than original steel fenders, which can reduce front axle weight by 50-100 pounds total. This weight reduction can slightly improve fuel economy and reduce tire wear. The change in weight distribution is minimal and won't negatively affect handling. Steel replacement fenders maintain similar weight to OEM parts with no noticeable change in truck dynamics.
