NEW • IN STOCK • READY TO WORK
2027 MACK PINNACLE LOWBOY TRACTOR
Available Now at Potomac Truck Group – Tidewater
Built for Heavy Haul Professionals Who Can't Afford Compromise.
When your business depends on moving oversized equipment safely, legally, and efficiently, every specification matters.
This 2027 Mack Pinnacle was engineered specifically for lowboy applications—not adapted after the fact.
From its factory-installed wetline system to its extended axle spread, every component was selected to maximize payload, improve permit flexibility, reduce maintenance, and keep your truck producing revenue.
PERMIT MORE. HAUL MORE. EARN MORE.
Factory Installed 13,200-lb Lift Axle
Positioned 56 inches ahead of the tandem, this factory-installed steerable lift axle creates additional axle spread to improve bridge formula compliance and increase permit capability.
That means:
✔ Greater legal payload potential
✔ Better weight distribution
✔ Increased versatility across multiple states
✔ Factory engineering and reliability
505 HP. 1,900 LB-FT OF TORQUE. LESS WEIGHT. MORE PAYLOAD.
Powered by Mack's legendary 13-liter MP8 engine, producing
505 Horsepower, 1,900 lb-ft of torque
Unlike larger displacement engines that simply add weight, the Mack 13-liter delivers outstanding pulling power while keeping chassis weight lower.
Why does that matter?
A lighter tractor means:
• More available payload
• Greater legal hauling capacity
• Increased revenue potential on every load
Every pound you save on the tractor is another pound you can legally haul.
THE 14-SPEED mDRIVE HD CHANGES EVERYTHING.
Forget wrestling a manual transmission.
This truck features Mack's heavy-duty 14-Speed mDrive HD Automated Transmission with:
• Ultra-Low Creeper Gear
• Multi-Speed Reverse
• Smooth automated shifting
• Excellent low-speed control
• Outstanding maneuverability on jobsites
Whether you're climbing onto a detachable trailer or backing into tight construction sites, the ultra-low gearing provides exceptional control while reducing clutch wear and driver fatigue.
The Hiring Advantage
Today's workforce has changed.
Many CDL drivers either:
• Never learned to operate a manual transmission
or
• Hold a CDL with restrictions prohibiting operation of manual-transmission trucks.
With the Mack mDrive, any properly licensed CDL driver can operate this truck—period.
That dramatically expands your available driver pool while eliminating one of the biggest barriers to staffing specialized equipment.
FACTORY PTO = FACTORY WARRANTY
Unlike aftermarket installations, this truck includes a factory-installed PTO and Parker hydraulic pump.
That means:
Factory engineered
Factory installed
Factory supported
Most importantly, the PTO and transmission are covered together under the same factory warranty program, providing greater confidence and eliminating finger-pointing between component manufacturers.
ENGINEERED TO STOP AS WELL AS IT PULLS
Heavy haul demands exceptional braking.
That's why this Pinnacle is equipped with:
14,600-lb Front Axle
with Air Disc Brakes
