FinditParts data shows U.S. heavy-duty truck parts prices cool to 0.4% year over year

FinditParts says its October 2026 Heavy-Duty Price Index shows national heavy-duty truck parts prices up 0.4% from a year earlier, while regional pricing ranges from -2.9% in the Northeast to +1.7% in the South. The report also finds distributor prices slipping below last year’s levels even as manufacturer prices hit a new high.

Why it matters: - Heavy-duty parts inflation is cooling nationally, but the new regional data shows fleets, repair shops and distributors are facing very different pricing conditions depending on where they operate. - The gap between distributor and manufacturer pricing suggests the market is not moving in one direction, which can affect purchasing, repair costs and inventory planning.

What happened: - FinditParts released its October 2026 Heavy-Duty Price Index, a monthly benchmark built from aggregated marketplace data. - The report adds a first regional view of distributor pricing. - National heavy-duty parts prices finished October 5.9% above January 2024 levels. - Year-over-year price growth slowed to 0.4% in October. - The report is available at the full report.

The details: - Year-over-year heavy-duty parts price growth has slowed for eight straight months, falling from a peak of 8.4% in February to 0.4% in October. - Distributor prices in the South were up 1.7% from a year earlier. - Distributor prices in the Northeast were down 2.9% from last October. - Distributor prices in the West were up 9% since early 2024, more than twice the increase in the South. - Over the past year, distributor prices rose in the South and Midwest and fell in the Northeast and West. - Distributor prices were 1.4% below year-ago levels overall. - Manufacturer prices reached a new index high of 106.7, with January 2024 set at 100. - Manufacturer prices were up 2.6% year over year. - Variation also showed up inside product categories. - In Driveline & Axles, Hardware, Fasteners & Fittings were up 19.5% versus January 2024. - In Driveline & Axles, Hubs & Related Components were up 4.5% over the same period. - In the same category, Axle Shafts were up more than 3% from a year ago. - Drive Shafts were up just over 1% from a year ago.

Between the lines: - The data suggests a national average can hide meaningful local price swings. - FinditParts is positioning the HDPI as a deeper pricing signal than broad inflation measures because it tracks the same SKU at the same location over time. - The company compares the scale of HDPI to the Consumer Price Index, which samples about 80,000 prices across the consumer economy. - FinditParts says motor vehicle parts and equipment make up about 0.3% of the CPI sample, mostly tires.

What the data covers: - The HDPI uses live inventory signals from about 3 million unique in-stock SKUs. - Those SKUs come from about 900 stocking locations. - The inventory represented totals about $7 billion. - Regional figures group distributor locations by U.S. Census region and reflect each region’s product mix. - Prior-month figures may be revised as additional data is added.

What's next: - FinditParts is expected to continue publishing the HDPI monthly, giving the industry a running read on price movement by region and subcategory. - The company says the index is designed to help distributors, manufacturers, dealers, repair shops and truck owners make pricing and buying decisions.

The bottom line: - Heavy-duty truck parts prices are still rising, but much more slowly, and the real story is the widening split by region, channel and subcategory.
