[QUOTE="Philo Beddoe, post: 1242575, member: 21915"] The info shared earlier by Frank is great info. But just a heads up- it is a generic reference to how a Torsen works. Our trucks do not have a 3:1 TBR, that is just the arbitrary number used in the example of how it functions. Ford SVT used a 2.5:1 TBR along with no preload. It is a design specific to the Raptor. No preload means that a complete loss of traction, as in when one front wheel is in the air, will transfer no torque. This design was meant to increase durability and help with road manners. It was also meant to work with the electronic traction nannies. With no preload, a complete loss of traction can be overcome by applying some brake, tricking the system into thinking there is some traction and thus transferring torque. With the electronic nannies on, the truck will apply brakes on it's own. Just wanted to hopefully add to the discussion, even though it's late. If anyone is interested I can also explain a little bit about what creates the difference in TBR between different Torsen models. [/QUOTE]
