International Truck Parts: The Complete Guide to Aftermarket Parts for International Trucks
If you own or maintain an International truck, finding quality replacement parts at affordable prices is essential to keeping your fleet running. International trucks — manufactured by Navistar International — are among the most popular commercial vehicles on North American roads, powering everything from long-haul freight operations to local delivery routes and vocational applications.
In this guide, we cover the most commonly replaced International truck parts, the most popular International truck models, and where to find the best aftermarket parts that deliver OEM-quality fit without the dealer markup.
Most Popular International Truck Models
International has a long history of building reliable commercial trucks. Here are the models you will see most often on the road today:
- International ProStar — The workhorse of long-haul trucking. The ProStar was one of the best-selling Class 8 trucks in North America before being replaced by the LT Series. Hundreds of thousands are still in active service and need regular parts replacement.
- International LT Series — The successor to the ProStar, the LT Series offers improved aerodynamics, fuel efficiency, and driver comfort. It has quickly become a fleet favorite for over-the-road applications.
- International DuraStar / MV Series — A medium-duty workhorse used in delivery, utility, and municipal applications. The DuraStar was rebranded as the MV Series in 2018.
- International WorkStar / HV Series — Built for vocational applications including dump trucks, concrete mixers, and refuse haulers. The WorkStar was rebranded as the HV Series.
- International HX Series — A heavy-duty severe-service truck designed for construction, mining, and logging operations.
- International TranStar — A regional haul tractor that bridges the gap between medium and heavy duty applications.
Most Commonly Replaced International Truck Parts
Whether you are maintaining a single International truck or managing an entire fleet, these are the parts categories you will replace most often:
Bumpers
International truck bumpers take a beating from road debris, loading dock impacts, and harsh weather. The International ProStar bumper and LT bumper are among the most frequently replaced parts. Aftermarket chrome and painted bumpers are available at 40-60% less than OEM pricing, with the same fit and finish quality.
Headlights and Lighting
International truck headlights are critical for safety and DOT compliance. LED headlight upgrades for the ProStar and LT Series provide dramatically better visibility and longer lifespan compared to factory halogen units. We also carry fog lights, tail lights, marker lights, and turn signal assemblies for all major International models.
Grilles
The International truck grille is one of the most visible parts of the truck and often the first thing to show wear. Aftermarket grilles for the ProStar, LT, and DuraStar are available in chrome and painted finishes, with options for bug screens and winter fronts.
Mirrors
International truck mirrors are essential for safe lane changes and backing maneuvers. Replacement mirror assemblies, mirror glass, mirror arms, and heated mirror options are available for all International models. Door mirror assemblies for the ProStar and LT are among our top sellers.
Hoods
A cracked or damaged International truck hood affects both aerodynamics and appearance. Aftermarket hoods for the ProStar and DuraStar are available in fiberglass and composite materials, offering the same fit as OEM at a fraction of the price.
Fenders and Body Panels
Road spray, salt, and debris take a toll on International truck fenders and body panels. Replacement fenders, quarter fenders, mud flaps, and splash guards keep your truck looking professional and protect critical components from corrosion.
Cooling System Parts
The International truck radiator and charge air cooler are critical for engine cooling, especially in trucks equipped with the Navistar N13 or Cummins X15 engines. Aftermarket radiators, coolant reservoirs, fan clutches, and water pumps are available for all International models.
Air Intake and Exhaust
International truck air filters, intake tubes, and exhaust components need regular replacement to maintain engine performance. DPF filters, EGR coolers, and turbocharger components are also available for emissions system maintenance.
OEM vs. Aftermarket International Truck Parts
Dealer parts for International trucks come with significant markups — often 2-3 times the price of equivalent aftermarket parts. Here is how they compare:
- Fit and Quality: Top-tier aftermarket International truck parts are manufactured to OEM specifications, using the same materials and engineering tolerances. Many aftermarket suppliers actually manufacture parts for both the OEM and aftermarket channels.
- Price: Aftermarket parts typically cost 40-70% less than dealer OEM parts. For fleet operators replacing multiple units, the savings add up quickly.
- Availability: Aftermarket parts are often available faster than dealer-ordered OEM parts, reducing downtime and getting your International truck back on the road sooner.
- Warranty: Reputable aftermarket suppliers offer warranties comparable to OEM parts, giving you confidence in your purchase.
