The active center diff outdrives are CNC-machined on precision German long-turn devices and are also constructed from HUDY toughened steel. The diff outdrives are additionally ground and strategically lightened to cut back rotating fat. The diff outdrives are then further hardened to ensure maximum power and longest lifespan. The diff outdrive shafts are in addition precision hand-ground to a really high tolerance to ensure an ultra-smooth tight fit in the diff body and diff gear.
