FinditParts launches heavy-duty truck parts price index showing 5.7% increase since 2024

FinditParts released the first monthly Heavy-Duty Price Index, a new benchmark built from live supplier inventory across roughly 3 million in-stock parts at about 900 locations. The inaugural report shows pricing is up 5.7% since January 2024, with some categories rising much faster than others and more increases potentially ahead.

Why it matters: - Heavy-duty truck parts are a core input for fleets, repair shops and distributors. - The new index gives the industry a category-level view of pricing, which can affect maintenance costs, repair planning and inventory decisions. - The report suggests price pressure is uneven, not broad-based, which matters for parts buyers trying to forecast where costs may rise next.

What happened: - FinditParts released the first edition of the Heavy-Duty Price Index (HDPI) on Oct. 13, 2026. - The index measures heavy-duty truck parts pricing using real supplier inventory, not surveys or list prices. - The free report is available at more information. - The inaugural HDPI shows heavy-duty parts prices were 5.7% above their January 2024 level as of September 2026.

The details: - The HDPI reached 105.7 in September 2026, using January 2024 as the 100 baseline. - Year-over-year increases have moderated through 2026, and overall prices were roughly flat month over month in recent readings. - Price changes vary sharply by category. - Driveline and axle parts are up 12.9% since January 2024. - HVAC parts are roughly flat at an index level of 99.0. - Manufacturer-level prices are still rising, up 1.9% year over year. - Distributor pricing held firmer in 2024 and rose more sharply in 2025 than the market overall. - In August 2026, federal data showed mixed signals for motor-vehicle parts, with the Consumer Price Index up 0.9% year over year and the Producer Price Index up 3.3%. - HDPI focuses specifically on the heavy-duty segment, rather than the broader economy.

Between the lines: - The HDPI is designed to fill a data gap in a market that has often relied on anecdotes and incomplete information. - The spread between categories suggests parts inflation is being driven by specific supply-and-demand dynamics, not a single industrywide trend. - Rising manufacturer prices can signal more cost pressure for distributors and fleets ahead, even if recent monthly changes look calmer. - The scale of the dataset is a key differentiator: HDPI draws on roughly 3 million unique in-stock SKUs across about 900 stocking locations, representing about $7 billion of inventory at supplier cost. - FinditParts says the index uses a matched-item approach, comparing the same SKU at the same location month to month. - The company also notes the Consumer Price Index samples about 80,000 prices across the whole economy, and motor vehicle parts and equipment make up about 0.3% of that basket.

What's next: - FinditParts plans to publish HDPI as a monthly benchmark. - The company expects the index to help fleets, shops and distributors see pricing shifts earlier and plan purchases more effectively. - Further movement in manufacturer prices could flow downstream into distributor and fleet costs in coming months.

The bottom line: - Heavy-duty truck parts inflation is still running above early-2024 levels, and the biggest cost pressure is concentrated in specific categories rather than spread evenly across the market.
