2014 Mack Granite GU713

The 2014 Mack Granite GU713 Quad Axle Dump Truck with a 20' Steel Dump Box is a severe-duty Class 8 vocational workhorse engineered for heavy aggregate, demolition, and excavation haulage. Assuming "204" was a quick typo for the highly standard 2014 model year, this variant represents a highly sought-after setup due to its high-capacity structural frame and its compliance with federal bridge weight formulas.
Mack MP7: The lighter, high-efficiency 11.0L alternative, putting out 405 horsepower
Transmission: Allison 4500RDS 6-speed automatic
Axle Configuration: (Quad-Axle Layout): Centers on a heavy 18,000 lb. front steering axle matched to a 46,000 lb. rear tandem drive axle cluster with full mechanical diff-locks. This is supplemented by a dual steerable air-lift pusher axle (typically 13,200 lbs.) positioned ahead of the rears to maximize legal payload geometry 
20-Foot Steel Dump Box: Built from high-strength abrasive-resistant steel. The Godwin 20-foot length represents the maximum standard frame length for a solo dump truck, allowing a vast material volume capacity optimized for demolition debris or massive rip-rap stone
