MT – Detroit Front Axle

Detroit® Front Axle

For over 70 years, Detroit Diesel Corporation has developed a legacy of reliability and efficient performance. These qualities have been transferred to steer and drive axles, the components that shoulder your load day in and day out. Detroit axles combine advanced design features and state of the art manufacturing processes and are designed specifically for FCCC chassis.

For the tightest turning radius and maximum maneuverability, the unique design of the Detroit steer axles’ I-beam and tie rod arm offer up to a 50° wheel cut. And by using needle bearings that roll against the kingpin instead of bushings that rub, they increase durability while reducing maintenance needs.

MT – Meritor Drive Axle

Meritor® Front Axles*

Meritor Front Axle

Enhance mobility for your fleet with Meritor front axles, which offer strength at lighter weights – increasing your payloads and raising your operating efficiencies.

  • Up to 420 capable double cardan joints to improve maneuverability by reducing the turning radius while protecting bearings against contamination without the use of external deflectors
*Available on gas chassis only
