Meet ‘Jack,’ Mack’s 800-hp mega crew cab pickup truck

Updated Sep 30, 2016

Last weekend at the Pocono Raceway, fans were treated to quite the sight when a massive pickup truck toting the American flag led the ceremonial laps at the Pennsylvania 400.

The pickup in question is named Jack and is the monstrous creation of Mack Trucks’ Customer Adaptation Center.

Given the nickname of Mack Trucks co-founder John M. Mack, the custom-built, all-wheel drive, mega crew cab pickup is based on a Mack Granite model and is powered by a 13-liter Mack MP8 engine providing a huge 800 horsepower and 2,800 lb.-ft. of torque.

“Jack is not only a celebration of our rich history, but also a demonstration of the high level of customization we’re capable of at our Customer Adaptation Center,” said John Walsh, Mack vice president of global marketing and brand management. The CAC is located inside Mack’s Lehigh Valley Operations assembly plant in Macungie, Pennsylvania, and customizes Mack trucks for customers whose needs go beyond typical factory options like adding extra brightwork for a custom long-haul sleeper or installing an all-wheel drive system for a municipal snow plow.

Jack rolled off the assembly line on October 27, 2015, the 151st birthday of Jack Mack, according to a Mack release. The chassis was then moved to the CAC to receive its modifications and custom fabrication work. Among Jack’s unique features are:

  • Custom-fabricated mega crew cab body and pickup bed
  • 46-inch tires mounted on custom wheels
  • All-wheel drive
  • Custom 8-inch dual exhaust
  • Back-up and side-view cameras
  • Touchscreen infotainment system
  • 3D-printed “Jack” name plates modeled on founder Jack Mack’s signature
  • 16,000 lb. winch

In addition to the image of the truck provided by Mack, we were able to dig up a few more images that show the truck in close-up detail from Facebook user Dan Hand, who says in his post that he works within the CAC.
