The Eaton Truetrac has been designed to fit straight into a M86 diff. That diff is fitted to all BA BF & FG XR6 turbos, XR8, F6’s, GT and GTP’s. The Eaton Detroit Truetrac® limited-slip differential is the pioneer in helical gear based traction technology. Wheel spin is limited by the differential, which employs pinion- and side-gear separation forces to automatically transfer torque to the wheel with the best traction. Mobility, stability and handling are enhanced, and drivers can be confident knowing that up to 3.5 times more torque is being transferred to the high-traction wheel. Operation of the Truetrac® is smooth and quiet, and the unit will engage without any driver knowledge or action required. It also has no wearable parts and requires no maintenance, meaning a lower overall cost for the customer. 00098764
