It comes with a forward- or rear- set steer axle from Meritor, AAC or Dana with capacities from 12,000 to 20,000 pounds, while Dana or Meritor rear axles range from 21,000-pound single to 46,000-pound tandems. The 4900-106 comes with Detroit Diesel’s DD13 with 350 to 450 horsepower and torque of 1,250 to 1,650 lb.-ft. Available transmissions include Eaton Fuller 10- to 18-speed manuals or Allison 3000, 4000, 4500 and 4700 automatics. The DD13 uses Blue-Tec selective catalytic reduction with exhaust aftertreatment setups that allow a “clean” back-of-cab.
