Meritor is introducing the 13X, a lighter more efficient carrier platform designed for class 6 and 7 applications, available for OEM production starting in the second quarter of this year. It doesn’t replace the 14X.

Engineered for a variety of medium-duty applications, including pick-up and delivery, beverage, utility, school bus, construction, and ambulance, the single-drive 13X uses the best technologies of Meritor’s 14X platform. Because the new axle includes the same housing, yokes, and seals as the 14X, the new axle system will be familiar to fleet technicians.

Available in a wide variety of ratios from 3.90 to 6.50 and with gross axle weight ratings (GAWR) between 17,000 and 21,000 lb, the 13X can be configured for most class 6 and 7 applications and fleet needs. The 13X is offered with standard differentials and is compatible with air drum or hydraulic disc brakes as well as parking brakes.

For limited application options that the 13X will not address, including ratios or driver-controlled differential locks, the 14X single-axle platform will continue to be available.
