m DRIVE
Available with optional 13- and 14-speed creeper gears, the Mack m DRIVE™ HD provides flexible gearing for low-speed applications, as well as improved startability for heavy loads, while maintaining proper gearing for fuel efficiency at speed.

Low-speed Creeper Gears
Geared up for any job
Mack’s HD is now 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.
Power Launch
Get out of the toughest spots
When rocking won’t release your truck from sand and loose soil, 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. (Available with Performance shifter package)
Grade Gripper
Winning the uphill battle
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.
Complete integration
Part of our legendary integrated powertrain, m DRIVE HD works seamlessly with Mack engines and axles for better efficiency, more uptime and lower costs.
Increased driver productivity
m DRIVE HD is automated, and that means less physical stress on drivers, so they can finish the job strong and stay focused.
Lighter than the rest
Even though it’s built strong, m DRIVE HD is hundreds of pounds lighter than the competitors, so you can ditch dead weight and increase your payload.
