Heavy-Duty Parts For Truck, Bus, and Off-Road Equipment.

Navistar International Truck Parts - A/C & Heater Specialists, Expanding Fast

International trucks cover more vocations than almost any other brand - linehaul, construction support, municipal, utility, ag - and TruckAC+ stocks the climate system parts to service that entire range. Our Navistar International inventory includes compressors, blower motors, condensers, evaporators, heater cores, receiver driers, expansion valves, fittings, control head assemblies, wiring harnesses, and electrical components, catalogued to specific models and applications, and our team will help confirm the right fit before you order.

Heavy-duty A/C is where TruckAC+ built its expertise, but our International parts offering doesn't stop there. We're expanding across additional truck and equipment systems - working toward a single, reliable source for heavy-duty operators who run International equipment across diverse and demanding environments.

Both OEM and aftermarket options are available. In-stock items ship same day from our warehouse, and manufacturer warranty coverage applies to most components - backed by top-tier brands and support you can count on.

Navistar International Truck Parts FAQs

International trucks span a huge range of applications. How do I know your parts cover my specific model?

Our catalog is organized by model and application, not just brand. International's lineup includes the LT Series, RH Series, HX Series, and legacy platforms like the 9200 and 9900 - along with medium-duty models like the MV Series. We stock parts across that range. If you're not sure which part fits your specific configuration, reach out with your model information.

Do you carry parts for both International semi-trucks and medium-duty vehicles like the MV Series?

Yes. Our Navistar International inventory covers heavy-duty linehaul and vocational trucks as well as medium-duty applications. Climate system components sometimes differ between weight classes, so always confirm the application when ordering.

My International's A/C system lost charge. What components should I be looking at?

A system that won't hold charge typically points to the compressor, condenser, evaporator, or receiver drier - or a combination. Fittings and hose connections are also worth inspecting. We stock all of these components for International applications. If the system has been contaminated, replacing the receiver drier along with the primary failed component is standard practice.

Are OEM International A/C parts significantly more expensive than aftermarket?

The price difference varies by component. Compressors and condensers tend to show the most meaningful spread between OEM and aftermarket pricing. For fleets managing per-unit maintenance costs, aftermarket options from reputable manufacturers offer a strong value without sacrificing reliability. Both options are available through TruckAC+.

How does shipping work for Navistar International parts orders?

In-stock items ship from any one of our fulfillment centers located across the United States. Shipping speed ultimately depends on your carrier selection and location, but we are sure to get the parts out fast.

Do your International parts come with any warranty protection?

Yes. Most parts in our inventory carry manufacturer warranty coverage, applying to both OEM and aftermarket components. The warranty is backed by the part manufacturer, providing real support if a component fails under normal operating conditions.
