The Eaton Detroit Truetrac differential is a helical-gear limited-slip differential designed to improve traction, acceleration, and handling in rear-wheel-drive applications. Its automatic operation transfers torque to the wheel with greater available traction, helping maintain forward momentum through changing road conditions without requiring driver intervention.

Built for smooth, quiet, and dependable performance, the Detroit Truetrac uses durable helical gearing and operates in both forward and reverse. It is maintenance-free under normal operating conditions and does not require special lubrication or friction modifiers. The optimized torque bias characteristics help deliver predictable handling and improved power delivery for street, performance, towing, and off-road vehicles.

This Eaton Detroit Truetrac differential is configured for 31-spline axle shafts with a 1.32-inch axle shaft diameter and supports ring gear and pinion ratios from 2.76 to 4.56. Its automatic engagement and versatile design make it a practical traction solution for many compatible rear axle assemblies. Verify axle configuration, spline count, shaft diameter, differential case requirements, and gear ratio before installation.
