“The investment to create a dedicated HDT product line at the Mack Experience Center will increase production efficiencies,” said David Hartzell, president of Mack Defense. “We are proud to continue the fulfillment of our current contract with the U.S. Army and support our armed forces.”

Previously, non-armored HDT vehicles started production at Lehigh Valley Operations (LVO), where all Mack Truck Class 8 vehicles for North America and export are assembled. The HDT vehicle was then transported to the Mack Experience Center, where final assembly including the dump body was added.

Production of the HDT trucks at the Mack Experience Center began in in the first quarter. Initial deliveries of the Mack Defense M917A3 HDT began in May 2021.

The production line is located in the Mack Experience Center in the former Customer Adaptation Center, where vehicle modifications for Mack trucks occurred. All of that space will be used for production. The Customer Adaptation Center has since moved to LVO.

The HDT is based on the civilian Mack Granite model. The vehicle is powered by a 13 L Mack MP8 440 diesel engine rated 440 hp with a maximum torque of 1660 lb. ft. the engine drives a six-speed Allison 4500 Gen5 automatic transmission, which combines with a Fabco TC142 transfer case to provide all-wheel drive.

Other driveline components include Meritor front (MX-810) and rear (ProTec Series 50) axles, Meritor Permalube drivelines and a Primaxx rear suspension.
