Frequently Asked Questions About International HX Frame & Chassis

What years and models of International HX trucks are these frame and chassis parts compatible with?

Our International HX frame and chassis parts are designed to fit HX Series trucks from 2017 to present, including HX515, HX520, and HX620 models. Each product listing specifies exact compatibility, but most components are engineered for both set-forward and set-back axle configurations. Always verify your truck's OEM and model year before ordering, as some parts may have mid-year production changes that affect fitment.

What gauge steel and materials are used in these frame components, and how do they compare to OEM quality?

Most of our International HX frame components are manufactured from heavy-duty 10-gauge to 7-gauge steel, depending on the specific part and application. Critical structural components like frame rails and crossmembers meet or exceed OEM specifications for tensile strength and durability. All steel parts feature either powder coating or e-coating for corrosion resistance, with many offering a 3-year warranty against rust-through.

Do I need special tools or professional installation for frame and chassis components?

Installation requirements vary by component. Simple bolt-on parts like mud flaps and light brackets can typically be installed with basic hand tools in 30-60 minutes. However, major frame components such as crossmembers, suspension hangers, or frame extensions require professional installation with proper lifting equipment, torque specifications, and alignment procedures. We recommend professional installation for any structural components to maintain warranty coverage and ensure safety.

What finish options are available, and which holds up best in harsh conditions?

We offer three primary finishes for International HX frame components: black powder coat, bare steel primer, and chrome. For maximum durability in harsh environments, black powder coating provides the best protection against road salt, chemicals, and weather exposure. Chrome offers a premium appearance but requires more maintenance. Bare steel primer options allow for custom painting to match your specific color requirements but need immediate finishing after purchase.

Can I mix aftermarket frame components with OEM parts, or do I need to replace everything as a set?

Yes, our aftermarket frame and chassis components are engineered to work seamlessly with existing OEM parts. Individual components like brackets, hangers, and crossmembers can be replaced as needed without requiring full system replacement. However, when replacing critical suspension or frame components, we recommend inspecting all related parts for wear and replacing any questionable items to ensure proper alignment and load distribution across the frame system.
