The Eaton Detroit Truetrac differential is a helical-gear limited-slip differential designed to improve traction, acceleration, and handling in vehicles equipped with a front Dana 44 axle. Its automatic operation transfers torque smoothly to the wheel with greater available traction, helping maintain forward momentum without driver intervention. The differential operates in both forward and reverse and is suitable for non-disconnect axle applications.

Built for dependable street and off-road performance, the Eaton Detroit Truetrac uses durable helical gearing for smooth, quiet operation and consistent engagement. Its maintenance-free design does not require special lubrication or friction modifiers, simplifying installation and long-term service. Optimized torque-bias characteristics help enhance vehicle control while preserving predictable driving behavior during changing traction conditions.

This Detroit Truetrac differential is configured for 30-spline axle shafts with a 1.31-inch axle shaft diameter and ring gear and pinion ratios of 3.92 and higher. It is intended for front Dana 44 applications that do not use axle disconnect systems. Verify axle configuration, spline count, ratio compatibility, and available clearance before installation. Professional installation is recommended to ensure proper setup and gear engagement.
