Dana has introduced the Spicer EconoTrek tandem axle for linehaul tractors. The 6×2 configuration, according to the company, reduces weight by up to 400 lbs compared to a 40,000-lb tandem drive axle. The EconoTrek combines Spicer S170 and S190 single-reduction drive axles with a new Spicer S20-045B tag axle.

For Class 8 applications, Dana has introduced the Spicer AdvanTEK 40. The 40,000-lb. tandem drive axle, the company notes, is designed to handle higher input torques with direct-drive transmissions requiring rear axle ratios from 2.26 to 2.79 and with overdrive transmissions in ratios from 2.93 to 3.91. Options for the AdvanTEK 40 include Dana’s wheel differential locks, lubrication pump, breather, and Spicer LMS and LMSi hubs.
