The Mack Pinnacle Axle Back DayCab (Standard Item #524) is approved for purchase through the U.S. General Services Administration’s (GSA) Auto Choice program. This versatile, fuel-efficient tractor features a 365-horsepower engine (1,450 lb.-ft. of torque) and a 4×2 driveline. It has a 60,000 lb. GCWR with 12,000-lb.-capacity front axles and 23,000-lb.-capacity rear axles.

The Mack Pinnacle DayCab represents the best in truck engineering. From a lightweight-yet-strong frame specially designed for heavy loads, steep grades and long hauls to a powerful and fuel-efficient MP engine that delivers the brawn you need to maximize payload, this tractor is built to boost profits. Our DayCab axle back configuration boasts sleek lines that look good and improve aerodynamics. And the axle positioning delivers maximum maneuverability as the front axles are set back on the frame for a superior turning radius in tight spaces.
