2026 MACK, GRANITE 64FR, Heavy Duty Trucks - Dump Trucks, MACK MP7-425M, Automatic, A Mack Granite isn't just a purchase; it's an investment with a higher ROI. When it s time to trade, the Mack Granite consistently commands a higher resale value than the Kenworth T480, International HV, Peterbilt 548, or Freightliner Business Class M2. This truck is mounting now, pic's are examples. Body spec's can still be modified if needed. WHY THE MACK MP7 BEATS THE "LITTLE GUYS" Don t settle for a 9L engine in a 11L world. This Granite is powered by the legendary Mack 11L MP7 engine. While competitors like Kenworth, Paccar, or Cummins rely on smaller 9L platforms, the MP7 offers: Superior Longevity: A 9L engine has to scream to keep up. The MP7 works smarter, not harder, leading to a significantly longer life expectancy and higher "B10" life ratings than any 9L engine on the market. Torque on Demand: More displacement means more lugging power when you're pulling out of a soft pit or climbing a grade. THE ALLISON ADVANTAGE: REAL AUTOMATIC POWER Forget the "Automated Manual" (AMT) options that lag, hunt for gears, and jerk in the mud. This truck features the Allison 4500 RDS True Automatic Transmission. Effortless Operation: No clutch wear, no shift interruptions, and zero learning curve for new drivers. Continuous Power: Unlike an AMT, the Allison provides uninterrupted power to the wheels, making it vastly easier to operate in heavy muck and tight job sites. In the world of off-road vocational applications, the choice between a proprietary Mack "Pedigreed" drivetrain and a vendor-supplied (Meritor/Dana) package often comes down to the balance between rugged durability and highway weight savings. For a heavy-duty dump truck frequently operating in pits, mud, or uneven job sites, the Mack Camelback suspension paired with Mack axles offers several mechanical advantages. One of the most significant advantages of Mack proprietary axles over Meritor or Dana equivalents is the top-mounted carrier design. Mack carriers are mounted on top of the axle housing rather than in the front. This provides several inches of additional ground clearance under the center of the axle. The top-mounted design also allows for a straighter driveline angle, which reduces vibration and wear on U-joints and bearings when the suspension is fully articulated off-road. BUILT TO OUTLAST: HARDOX AR-450 STEEL Most "standard" beds are built from mild steel which means they ll be dented, rusted, and worn thin in three years. This 17-foot bed is constructed from Hardox AR-450 wear plate. Impact Resistant: It bounces back where mild steel stays bent. The "Secret Weapon": Equipped with an upgraded Two-Way Tailgate. Whether you are spreading gravel or dumping oversized debris, this design makes your truck the most versatile tool in your fleet. Plenty of room to add a liftaxle if you want to increase your payload. We have 13LK steerable lift axles in stock for quick upfitting to your truck. WARRANTY
