International DuraStar Frame Crossmembers & Covers

Frequently Asked Questions About International DuraStar Frame Crossmembers & Covers

What are frame crossmembers and covers used for on my International DuraStar?

Frame crossmembers are structural components that run laterally across the truck's frame rails, providing rigidity and support for the chassis while helping to maintain proper frame alignment. Covers are typically used to protect these crossmembers or nearby components from road debris, moisture, and corrosion. Together, they help preserve the structural integrity of your truck's frame over time.

How do I know if a crossmember or cover will fit my specific DuraStar model?

Fitment can vary based on the model year, wheelbase, and configuration of your International DuraStar, since frame designs have changed across production years. We recommend checking the listed specifications on each product page and comparing them to your truck's frame measurements or existing part numbers. If you're unsure, our team can help you verify compatibility before you order.

What materials are these crossmembers and covers made from, and how durable are they?

Most crossmembers are made from heavy-gauge steel to match OEM strength requirements, while covers may be steel, aluminum, or coated composite materials depending on their purpose. Many parts come with a protective coating or finish, such as powder coat or e-coating, to help resist rust and corrosion from everyday road exposure.

Can I install a replacement crossmember or cover myself, or should I have a professional do it?

Installation difficulty depends on the specific part and its location on the frame. Covers are often straightforward to install with basic hand tools, while structural crossmembers may require frame alignment, welding, or specialized equipment to ensure proper fit and safety. If the replacement affects the truck's structural integrity, we recommend having the installation performed or verified by a qualified technician.

Will replacing a damaged crossmember affect my truck's warranty or inspection compliance?

Using a properly fitted replacement part designed for your DuraStar model should not negatively affect compliance, but any frame-related repair should be done to restore the truck to its original structural specifications. If your truck is still under a manufacturer or fleet warranty, check with your dealer or warranty provider before making frame modifications, as improper repairs could impact coverage or inspection results.
