2026 Mack GR64F

Category: Trucks (Dump). Duty cycle suggests municipal and site work, short haul, frequent stops, and PTO driven hydraulics. Low mileage and new condition point to minimal wear on steering, brake, and suspension wear points, with the real story being spec alignment for payload and drivability rather than prior service history. Powertrain centers on a Mack MP7 rated at 395 hp matched to an Allison 4500 RDS 6-speed automatic. Rear gearing at 3.98 favors controlled startability and grade performance over high-speed cruise, a sensible match for a tandem dump application. Axle ratings at 18k front and 44k rears, plus a 62,000 GVWR, put it in a common vocational weight class where tire selection, body spec, and local weight laws dictate final payload. Suspension is Mack Camelback multileaf SS44 at 44k, a vocational setup known for durability under point loads and uneven jobsite surfaces, with a tradeoff of a firmer ride compared to air. Frame rails, spring packs, and torque rod bushings are the areas to watch once it starts seeing off-road articulation, along with driveline angles and U-joint life under repeated dump cycles. Cab and chassis details include a 218-inch wheelbase and white paint, with overall maneuverability aimed at tighter work zones rather than long wheelbase stability. Identification is documented by serial 1M2GR2GCXTM053541 and stock 70787, with ECM details not provided, so engine hours and fault history would need to be pulled during delivery inspection or first service.
