The MP7 is about 51 pounds lighter with up to 425 horsepower and 1,560 lb.-ft. of torque. The engine features an updated wave piston design that, in conjunction with the new common-rail fuel injection system, enables more complete combustion of fuel resulting in reduced emissions and improved efficiency. Combined with a two-speed coolant pump, these features increase MP7 fuel efficiency by up to 2.1 percent.

Mack Granite models for concrete mixer applications come standard with Mack ClearTech One, a single-package Exhaust After treatment System (EATS) that frees up frame rail space and reduces weight by approximately 17 pounds. With Mack ClearTech One, the diesel particulate filter (DPF), selective catalytic reduction (SCR) technology and diesel exhaust fluid (DEF) dosing system are all combined into one unit. With the rail space gained, customers have more space to add water tanks and chutes with more wheelbase flexibility than before.

Mack Granite mixers come ready for upfit right from the factory with a rear-engine PTO, a special mixer cross-member designed for mounting of the mixer barrel pump, frame rail transition plates for mixer body mounting and an additional access panel in the cab floor to service the rear-engine PTO. Mack’s BodyLink III bodybuilder connector simplifies the installation of the body to the chassis and facilitates communication to the truck ECU without compromising quality from bodybuilder wire splicing. Post block terminals are also conveniently located in the top of the dash for additional connection points.

All Mack Granite models are backed by Mack GuardDog Connect, Mack’s proactive diagnostic and repair planning system. The telematics system monitors fault codes that could potentially shut down a truck. GuardDog Connect enables quick diagnosis of issues, proactive scheduling for repairs and confirmation that needed parts are in stock and ready to install, all while the truck is still on the job.
