Tech Insight
Limited slip differentials offer a balance between open differential street manners and the increased traction of a locker. The Dana 44 Dura Grip uses clutch-based positraction technology to transfer torque to the tire with the most traction while still allowing controlled differentiation during turns and mixed traction situations.
