Mack Trucks

For over two decades, Francis Enterprises has been a cornerstone of Oklahoma’s growth, delivering heavy-duty results across construction, demolition, oil field services, and aggregate hauling. While their fleet has seen more than 100 trucks pass through over the years, one brand has always held a permanent spot at the center of their operations: Mack. On their farm, they actively collect and preserve vintage Mack trucks, including classic B models, R models, and a legendary E9 Super-Liner. In fact, their passion for these trucks is so deeply rooted that when they welcomed a baby boy 15 years ago, they proudly named him "Mack." We are incredibly honored to be part of the Francis family legacy. Thank you for trusting Mack to help move Oklahoma forward for generations to come. 🚛🌾 📅: August 2026 #MackCalendarContest winner

Building the Hoover Dam stands as one of the greatest civil engineering feats in history, and Mack Trucks was there. 💪 From 1931 to 1936, contractors relied on the rugged Mack AC "Bulldog" and specialized 1932 Mack AP 16-30 ton trucks to move millions of cubic yards of material through Black Canyon. These machines handled the steep, unfinished terrain and extreme 120 degree desert heat, establishing a legacy of American engineering reliability. The orange truck displayed is a restored 1932 Mack Model AP designed specifically for the construction of the Hoover Dam. Restored by Ron Carey, it sits at the Pioneer Acres Museum. #America250

Entering a demanding worksite every day means navigating a shifting landscape of potholes, debris, and unpredictable obstacles. To give drivers the ultimate daily confidence, we completely redesigned the suspension system of the new Mack Keystone to handle the unknowns of any environment. The Keystone features a completely overhauled cab suspension and rear suspension, anchored by the industry-leading MaxRide. By protecting drivers from harsh vibrations and terrain impacts, the Keystone minimizes fatigue and keeps operations running smoothly from start to finish.

Where history meets innovation, you'll find Mack. Every modern Mack truck carries a visual tribute to the borough where the Bulldog was born. In 1900, Jack and Gus Mack established the company in Brooklyn, New York. Decades later, when it came time to engineer a bold new face for our highway lineup, our design team drew inspiration from the architectural lines of the iconic Brooklyn Bridge.🌉 The result was the structural support bar that holds the "MACK" nameplate on the grille. Known internally as "the bridge," this signature element serves as a unifying family look across our entire modern fleet. #America250

We didn’t just update the Mack MP13, we completely rebuilt it from the inside out to deliver our most efficient and powerful 13-liter engine to date. By incorporating a new wave piston, the re-engineered MP13 achieves up to a 3% improvement in fuel efficiency. Peak torque kicks in at 900 RPM and climbs all the way to 540 HP and 1,950 lb-ft of torque. The engine is paired with a next-generation aftertreatment system that meets strict EPA 2027 standards without adding a single maintenance step to your routine. The Mack MP13 is the lowest emission engine we have ever produced, built to ensure your fleet continues to deliver more. 🚛
