According to the latest release of ACT Research’s State of the Industry: U.S. Classes 3-8 Used Trucks Flash, preliminary same dealer retail sales of used Class 8 trucks declined for a second consecutive month in September, falling 7% month-over-month.
While auction sales surged 28% and wholesale transactions slipped 6% from August, total preliminary sales across all channels were up 6% sequentially, signaling that demand for used trucks remains fundamentally solid despite mixed results by channel.
The preliminary average retail price for same dealer sales of used Class 8 trucks softened more than seasonally expected, dipping 1.5% from August to $61,000. Pricing in both auction and wholesale markets also contracted, with the combined preliminary average sale price for all units dropping 7.1% month-over-month.
“While tighter inventories have been a persistent theme, it’s clear that higher interest rates and ongoing challenges in the driver pool and fuel costs are also influencing the used truck market,” said Steve Tam, Vice President at ACT Research. “Despite these headwinds, the sequential uptick in total sales and continued strength in freight activity suggest that underlying demand for used equipment remains resilient.”

According to the latest State of the Industry: U.S. Classes 3-8 Used Trucks report by ACT Research, same dealer used Class 8 retail truck sales declined 24% month-over-month in August, counter to the typical seasonal increase, while the average retail sale price increased 2.2% to $64,367. Compared to August 2025, retail sales were up 12% year-over-year and prices rose 11%.

“The notable drop in used Class 8 sales this month is not necessarily a reflection of weaker demand, but more likely a result of tightening inventory,” said Steve Tam, Vice President at ACT Research. “Dealers across the country are reporting that used truck inventory is increasingly hard to come by, and our analysis of multiple advertising sources confirms that available units are down meaningfully from earlier in the year. With new truck sales also running below last year’s pace, fewer trades are making their way into the used market, supporting higher prices despite lower sales volumes.”
Compared to May 2026:
- Average retail volumes increased 10%.
- Retail price increased 2%.
- Miles increased 3%.
- Age declined 2%.
