Ford’s toughened up F-150 SVT Raptor has been a hot-seller since its launch back in 2009 and to keep things bubbling along we’ve seen a few major updates made in the meantime, although the winning formula of a purpose-built off-road performance pickup has stayed true.

We now have a new 2012 Ford F-150 Raptor, once again demonstrating Ford’s focus on raising the bar for off-road capabilities in a production truck, offering plenty of extras and all the toughness that we’ve come to love in the F-150 SVT Raptor line.

A new Torsen front differential is one such upgrade, helping to increase grip significantly on the front end of the truck and improve its capabilities in handling obstacles, slippery conditions and steep grades--even when the traction is split between the front tires.

It relies on an internal helical gearset, which is used to help force torque from the 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.
