About the Mack Pinnacle

The Mack Pinnacle is a Class 8 highway and regional tractor introduced in 2006, serving as Mack's main on-highway model before the Anthem took over the long-haul role. Offered in axle-back and axle-forward configurations as a day cab or sleeper, the Pinnacle is used for long-haul, regional, and some vocational work. It is powered by Mack's proprietary MP7 and MP8 engines, paired with the Mack mDRIVE automated manual or Eaton Fuller manual transmissions. The Pinnacle remains common in regional and vocational fleets and in the used market.
