Frequently Asked Questions About International WorkStar Fender Extensions

What are fender extensions used for on an International WorkStar?

Fender extensions are add-on panels that widen or extend the coverage of your existing fenders. They help block additional road spray, mud, and debris from being thrown onto the cab, trailer, or nearby vehicles, especially when running wider tires or after-market wheels that extend beyond the stock fender line.

Will fender extensions fit my specific WorkStar model year?

Fender extension fit can vary depending on the model year of your WorkStar and the style of fender currently installed on the truck. Before ordering, check the listed year range and fender style compatibility on the product page, and compare it against your truck's existing fender setup to confirm a proper match.

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

Fender extensions are commonly available in materials such as poly, rubber, or metal, each offering different levels of flexibility and durability. Poly and rubber options tend to resist cracking from road debris and flex on impact, while metal versions offer a more rigid, OEM-style look. Choosing the right material often comes down to the balance of durability and appearance you're looking for.

Are these extensions easy to install, and do I need special tools?

Most fender extensions are designed to bolt on or clamp onto your existing fender using basic hand tools such as a drill and wrenches. Installation typically involves aligning the extension with the existing fender edge, drilling mounting holes if they are not pre-drilled, and securing it with the provided hardware. Always review the specific installation instructions included with your extension before starting.

Do fender extensions come pre-drilled, or will I need to drill mounting holes myself?

This depends on the specific product. Some fender extensions come with pre-drilled mounting holes designed to line up with common WorkStar fender configurations, while others are sold undrilled to allow for a custom fit. Check the product description for details on drilling requirements before you buy so you know what tools and prep work to expect.
