Dana Spicer EconoTrek 6x2 axles on Kenworth Class 8 trucks

Dana Spicer EconoTrek 6×2 axles available on Kenworth Class 8 trucks

Kenworth now offers the new Dana Spicer EconoTrek 6×2 tandem axle for order with new Kenworth Class 8 on-highway trucks.

Key benefits of the Spicer EconoTrek lightweight drive and tag axle configuration include enhanced fuel economy, weight savings, improved performance and reduced maintenance, said the company.

“The 6×2 configuration is becoming more popular with fleets and truck operators in their efforts to achieve fuel economy gains while also saving weight and increasing payload,” said Kurt Swihart, Kenworth marketing director. “The addition of Spicer EconoTrek provides Kenworth customers with yet another avenue to fuel efficiency.”

According to Dana, Spicer EconoTrek is up to 3% more fuel efficient compared to traditional 6×4 tandem axles. It also is more than 300 lbs. lighter than Kenworth’s standard 40,000-lb. drive axle configuration. The drive and tag axles can accommodate both dual and wide-base tires and gear ratios range from 2.53 to 7.83.

“EconoTrek is also a good fuel-efficiency option for the Kenworth T680 Advantage, which already is Kenworth most fuel-efficient truck,” said Swihart.

Dana notes that EconoTrek features a robust housing design. It is optimized for use with electronic controlled load distribution air suspension systems and must be specified with the Kenworth AG380 or AG400L suspensions. Operators also must spec a driver-controlled differential lock and the Bendix eTrac Traction Enhancement option, which transfers weight to the drive axle for better low-speed traction.

Class 8 orders strong in February

Even when seasonally adjusted, ACT says preliminary order numbers for February are up 5% over January.

According to the latest numbers from ACT Research, preliminary North America Class 8 net orders were 27,700 units, up 600 units from January and 16% from a year ago. With the fourth-largest seasonal factor of the year at 8%, seasonal adjustment reduces February’s Class 8 intake to 25,600 units, up 5% from January.

“Weak freight and carrier profitability fundamentals, and large carriers guiding to lower capex in 2024, would imply pressure in U.S. tractor, the North American Class 8 market’s largest segment,” said Kenny Vieth, ACT’s president and senior analyst. “While we do not yet have the underlying detail for February order volumes, Class 8 demand continuing at high levels again this month suggests that U.S. buyers continue as strong market participants.”
