Navistar Defense LLC said the independent suspensions will improve the maneuverability of older vehicles used by U.S. military forces.
"We are proud to offer economical enhancements to improve mobility and survivability of fielded units," said Navistar Defense President Archie Massicotte.
"Our ability to jointly create and rapidly integrate new components, subassemblies and rolling chassis off commercially based platforms creates value for the military acquisition community.
"Integrating proven commercial components into the MaxxPro fleet results in an overall lower cost of ownership for the government and ultimately the taxpayer."
The contract to Navistar for 650 DXM independent suspension kits was issued by the U.S. Marine Corps System Command and complements an earlier order for chassis upgrades to more than 2,700 MRAP vehicles.
The MaxxPro Mine Resistant Ambush Protected vehicle was first ordered by the U.S. Marines in 2007. The wheeled vehicle, mainly used for troop transport, features a V-shaped hull to mitigate the blast of explosive devices beneath the MRAP. A later variant, the MaxxPro Plus, added protection against explosively formed penetrator weapons and also featured increased engine power and payload capacity.
Navistar said the new suspensions on MaxxPro MRAPS enhance commonality with the newer vehicle.
The order is worth $110 million. Work on installing the suspension kits will be performed in Kuwait beginning in August and ending in October.
