Truck Parts Prices Are Up About 6% Since January 2024, a New Index Says, on Top of a Record $2.336 Per Mile for Truckers to Run

By Big Rig Daily Staff

Truck parts are costing more, according to the first release of a new price index for heavy-duty parts. FinditParts' Heavy-Duty Price Index says the price of truck parts is up about 6% compared with January 2024, Land Line reported on Nov. 2, 2026. The increase adds to other costs truckers already face, including fuel and insurance.

What the index found

Land Line says the index found uneven increases across categories. Driveline and axle prices saw the highest increase, at 13%. HVAC parts stayed mostly flat. Most of the increases happened last year, and for most of 2026 the increases in truck part prices have slowed down.

Prices at the manufacturer level, however, remain elevated at nearly 2% year over year, according to FinditParts. That could eventually reach the parts counter. FinditParts CEO Matt Schweickert said in a statement: "Headline inflation may be cooling, but manufacturers' pricing is still climbing. That usually means more cost is working its way toward distributors and fleets in the months ahead."

The bigger cost picture

Land Line puts the parts figures next to the American Transportation Research Institute's latest Analysis of the Operational Costs of Trucking. ATRI reported that average operating costs hit a record high of $2.336 per mile last year, including $0.215 per mile for repairs and maintenance. Land Line notes that even truck drivers who work on their own trucks are likely to see higher totals at the bottom of their receipts.

Why prices are up

The index does not explain why prices rose. Land Line says one possible explanation is tariffs. Last November, the federal government put a 25% tariff on medium- and heavy-duty trucks and parts. Before that, Land Line reports, domestic truck-part makers faced a 50% tariff on aluminum, copper and steel that took effect earlier that year. Land Line presents this only as a possibility.

How the index works

According to Land Line, FinditParts' index drills down further into truck part prices than government data does. The Consumer Price Index and the Producer Price Index both look at all motor vehicle parts without separating out truck parts. Those indexes follow tens of thousands of prices across the country, while FinditParts' index analyzes millions of product listings, known as SKUs.
