Ford has announced that the 2012 F-150 SVT Raptor will be available with a new front Torsen differential.
An internal helical gearset is used to help force torque from the front wheel that is losing traction to the wheel with traction. The system is set with a torque bias ratio of 2.5:1 to help multiply torque from wheel to wheel and the preload is set to zero to help minimize steering feedback.
Ford says that SVT and Torsen worked with the traction control team to further enhance the brake traction control system to improve the Torsen's capabilities. Special modifications were made for the differential's use on the Raptor, with a redesigned case created specifically for the truck's high-torque application.
