The Eaton Detroit Truetrac (MPN: 913A610) is a helical-gear style, limited-slip differential (LSD) engineered to provide smooth, automatic traction on demand. Unlike traditional clutch-type differentials, the Truetrac utilizes parallel axis helical gears to manage torque bias. This design eliminates the need for friction modifiers or special lubrication while providing maintenance-free operation for the life of the unit. During normal driving, it performs like an open differential; when one wheel loses traction, the internal gears transfer torque to the high-traction wheel to maximize acceleration and stability.
