Mack Pinnacle™ combines the legendary power and reliability with modern technology and an aerodynamic design. The result is a workhorse ready to take on any job while making every drop of fuel count. Pinnacle’s lightweight-yet-strong frame is built for heavy loads, steep grades and long hauls. And a powerful and fuel-efficient MP® engine delivers the brawn you need to maximize payload. But it doesn’t end there. Power gives way to style with the dominant chrome grille, Rawhide Edition interior and elevated seat position. Drivers of this truck aren’t just hauling heavy transport; they’re carrying pride.

  • Pinnacle is versatile, and can be spec’d in an array of configurations for different applications
  • Aerodynamic design improves driver visibility and cuts fuel costs
  • Under the hood, the MP Engine series has plenty of horsepower and great highway torque profiles
  • Pinnacle’s proven Advantage chassis is lightweight-yet-strong and can be optimized to fit the job

Pinnacle™ Sleepers are designed for driver comfort as well as heavy loads, steep grades and long hauls. They’ve got the brawn and fuel efficiency to run longer and maximize your bottom line. There are five sleepers available:

  • 48- and 56-inch Flattops, 60- and 70-inch mid-rise and our 70-inch high-rise. All sleepers are available on both Pinnacle Axle Back or Axle Forward models.

We’ve been an industry leader in vehicle stability systems for over a decade, and every Pinnacle comes with Roll Stability Advantage to protect drivers using sensors that respond to hazardous situations. In addition, a lower center of gravity and a four-corner frame mounted cab means that your Pinnacle will be completely stable.

Available with Axle Forward, the optional Rawhide has maximum visual impact with exterior bright finish, brushed nickel dash, leather-grip steering wheel, two-tone seats and more.
