Parts pricing for heavy-duty truck repair has seen distributors cutting prices compared to year-ago levels in some regions, while climbing further in others. Inflation that was widespread for parts, particularly through 2025, has widely cooled, however. National year-over-year comparisons showed price growth slowing to just 0.4% in October.
That's all according to the October edition of the Heavy-Duty Truck Parts Price Index report from online parts marketplace FindItParts.
Looking back to January 2024 pricing levels, parts are fetching 5.9% more overall. Yet beneath the national average are divergent trends between parts distributors and manufacturers, as well as wide gaps across U.S. regions.
Variance between distributors and manufacturers, regions
The October data highlighted a growing disconnect between what manufacturers charge and what distributors advertise on their shelves. Manufacturer prices climbed to a new index high of 106.7 (representing a 2.6% increase year-over-year), while distributor prices slipped into a deflationary trend, sitting 1.4% below year-ago levels.
Price growth across the board has cooled for eight consecutive months, falling significantly from a peak of 8.4% in February.
FindItParts for the first time showed a regional view of distributor pricing across U.S. Census regions, showing inflation and deflation are hitting different parts of the country unevenly.
Matt Schweickert, CEO of FinditParts, emphasized broad national averages can often conceal critical local dynamics: "A national average masks this variation that matters to the fleets, repair shops, and distributors navigating the context of their own specific markets."
South: Prices experienced upward momentum, rising 1.7% year-over-year.
Midwest: A modest year-over-year increase of 1.3%.
West: A -1.6% dip compared to last year, though the region remains up 9.0% cumulatively since early 2024.
Northeast: The sharpest -2.9% decline for distributor prices year-over-year.
In the full report, readers can access further data showing volatility for parts pricing at the product category level. Consider the Driveline & Axles category as an example, encompassing an inventory value of $884.3 million across nearly 97,700 unique products:
Hardware, fasteners, and fittings have experienced the most dramatic climb, surging 19.5% compared to baseline figures from January 2024, despite holding flat in October compared to September.
At the same time, drive shafts, accounting for the largest share of driveline inventory value at 30.4% of the total, rose just a modest 1.3% year-over-year while dipping -0.5% in October.
