Adding your products to cart

The International WorkStar Frame Crossmembers & Covers category offers essential components for maintaining and customizing your semi-truck. It includes walking beams, crossmember brackets, and fiberglass rear frame covers, all designed for durability, protection, and enhanced appearance. These parts are built to handle the demands of the road and improve both function and style. Whether replacing damaged parts or adding custom upgrades, this category provides high-quality solutions to keep your WorkStar running smoothly and looking great.

Frequently Asked Questions About International WorkStar Frame Crossmembers & Covers

What are frame crossmembers and covers used for on an International WorkStar?

Frame crossmembers connect the two main frame rails on your WorkStar, adding structural rigidity and helping the chassis handle torsional stress, load weight, and road vibration. Covers are used to shield components mounted near or on the frame, such as wiring, fuel lines, or crossmember sections, from road debris, moisture, and corrosion.

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

Fitment can vary by model year, cab configuration, and chassis length, so it is important to check the part number and application details listed on each product page against your truck's VIN or existing part number before ordering. If you are unsure, our team can help confirm compatibility based on your truck's specifications.

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

Most crossmembers are made from heavy-gauge steel to match OEM strength requirements, while covers may be steel or other durable materials depending on their application. Finish options, such as raw steel, primed, or coated, affect how well the part resists rust and wear, so choosing a finish suited to your operating environment can extend service life.

Can I install a replacement crossmember or cover myself, or do I need a professional?

Covers are generally straightforward to install with basic tools and can often be handled in a shop or even in the field. Crossmembers involve structural bolt patterns and sometimes welding or precise alignment with the frame rails, so we recommend having them installed by a qualified technician to ensure proper fit and safe load-bearing performance.

Will replacing a crossmember or cover affect my truck's warranty or DOT compliance?

Using a replacement part that matches OEM specifications should not negatively impact structural compliance, but any frame modification should be inspected to confirm it meets DOT frame integrity standards. If your truck is still under manufacturer warranty, check with International or your dealer before making frame-related repairs to avoid any warranty complications.
