Looking for the combination of a roomier cab, increased driver comfort but don’t want to give up the rugged reliability you’re used to in the MR Mack? Here is the answer. With the ride quality and comfort of a conventional cab, flexible engine options also means there is no limit to power.


The MP® engine by MACK deliver you an edge on the competition. It is highly fuel-efficient, while also delivering plenty of horsepower (from 325 to 505 HP) and superior low-end torque.

An air-suspended driver’s seat shields the driver from bumps in the road. And the airbag- and shock-mounted steel cab, stabilized with sway bars, soaks up the rough stuff from even the most punishing jobsites.
