Aftermarket direct-replacement parts for International trucks (LT and more) — what we stock, how the model families differ, and how to verify fitment by VIN or cross-reference before you buy.
International models we stock parts for
PartStop carries premium-quality aftermarket direct replacements for International trucks including LT, LoneStar, ProStar, HX, HV, MV, DuraStar, WorkStar, 9900i, 4300/4400 — running International A26 and Cummins X15 / L9 power. Every part ships from Tacoma, WA the same business day when ordered before the daily cutoff, with free standard shipping on orders over $100 and a 6+ month warranty.
Know your model family before ordering
International (Navistar) runs from the aero LT Series and ProStar on the highway to the DuraStar/MV medium-duty workhorses in every city fleet. The LT took over from the ProStar in 2017 — front-end parts differ between them, so match the model, not just the year.
Vocational HX/WorkStar trucks live hard lives: bumpers, mirrors, steps and lighting take damage long before the drivetrain wears out. That's exactly the class of part where a premium-quality aftermarket direct replacement saves real money over the dealer counter.
Three ways to guarantee the right fit
- VIN search: paste your International VIN into the catalog search — you get the decoded truck plus only the parts verified to fit that build.
- Cross-reference number: search the number stamped on your old part; our listings match by verified cross-references, not photos.
- Call us: (253) 600-1351 with the VIN and part number — we confirm fitment before you pay. Wrong-part returns waste a week; a 2-minute check doesn't.
