North American Class 8 orders in June approached replacement levels and reached the second-highest volume of the year on what may have been a one-off event and not the start of a consistent rebound, according to industry analysts. Preliminary net orders rose 23.2% to 16,000 compared with 12,979 a year earlier, ACT Research reported, citing truck makers’ initial data. The year-over-year increase was the first since January and only the third since October 2018. January saw this year's most orders at 17,700. North American replacement Class 8 levels are accepted to be 20,000 units a month. Year to date, orders dropped 24.7% to nearly 66,000 compared with more than 87,000 in 2019.
