2026 Mack Granite Heavy Haul Tractor
Built for maximum pulling power and durability, this Granite Heavy Haul comes equipped with a 505 HP Mack MP8 engine and the TMD14AFO-HD Mdrive 14-speed manual transmission for superior control under load. Features include full disc brakes, interwheel diff lock, and a 20K liftable pusher axle for added stability and payload flexibility. The long 272" wheelbase supports a Holland sliding fifth wheel, while dual fuel capacity (118 gal LH / 72 gal RH) keeps you working longer. Finished with aluminum wheels and standard cruise control, this truck is ready for serious heavy-haul performance.
