Key Features & Benefits
Reinforced for demanding applications
Roll over your toughest challenges
mDRIVE HD is engineered with two additional low gear ratios for vocational work, plus multi-speed reverse gears for more startability, maneuverability and flexibility in low-speed applications. So, no matter the job, you’ve got the ability to dominate.
Low-speed creeper gears
When rocking won’t release your truck from sand and loose soil, mDRIVE HD allows you to raise the engine RPM and torque before engaging drive mode to free your vehicle from spots that would sink the other guys.
Power Launch
Grade Gripper holds the truck on an incline for up to three seconds after the brake pedal is released. So, there’s no dangerous or awkward rolling backwards when stopping on a grade.
Grade Gripper
Don’t let troublesome terrain bog you down. When your truck gets stuck, mDRIVE HD rocks the vehicle back and forth to break you free.
Rock Free
Maximize Mack PowerLeash engine braking, with downshifts to high RPM to provide the highest amount of compression braking available.
MaxxBrake
Superior low-speed control
Optional 13-speed configuration
Features low reduction creeper gear for improved startability on steep grades and with heavy loads.
Optional 14-speed configuration
Adds ultra-low-speed reduction gear ideal for precision work like curb pouring and loose soil conditions.
Multi-speed reverse gears
Reverse gear ratios for enhanced maneuverability in tight job sites.
