 The front axle shafts used on the Callaway 4.6 HSE have been strengthened to withstand the increased torque to the front wheels from the engine and transmission changes.A material change in the axles ensures durability will be maintained for the front axle half shafts.<>

Callaway decided to use a four-pin front differential to accommodate the increased torque rather than the two-pin front diff used on standard production Range Rovers.
