Detroit Diesel has introduced new Model 6 Detroit drive axles. Available in single drive 4×2 or tandem 6×2 configurations with ratios from 2.28 to 5.88, the new axles are said to be designed with the latest features and technology, ultimately resulting in smoother performance and better fuel economy. 

The axles include new features such as weight-optimized housings, hollow axle shafts, and an internal baffle that reduces oil-churning inefficiencies while cruising.

The 4×2 single drive axle, for LTL-spec Freightliner Cascadia and M2 112 trucks and tractors, has a weight rating of up to 23,000 lb and a 1750-lb-ft torque capacity.

For weight-sensitive applications, the 6×2 tandem with tag axle has weight ratings up to 40,000 lb, also with 1750 lb-ft torque capacity. With a single drive and tag axle, it has the capacity of a tandem axle while shedding 431 lb. And because it doesn’t have a rear carrier or inter-axle differential, its efficiency is further improved by reducing moving parts. Ratios range from 3.91 to the fastest 2.28, which is offered exclusively in the integrated Detroit Powertrain which also includes the Detroit DD15 engine and Detroit DT12 automated manual transmission, further benefitting fuel efficiency.
