Brief Description: The Eaton Detroit Truetrac Differential is a helical-gear limited-slip differential designed to improve traction, acceleration, and handling in vehicles equipped with a rear Dana 60 axle. Its automatic operation transfers torque to the wheel with greater traction without requiring driver input, helping maintain smooth and predictable performance in forward and reverse.

Built for applications using 35-spline axle shafts with a 1.50-inch axle shaft diameter and a 4.56-and-up ring gear and pinion ratio, the Eaton Detroit Truetrac 915A386 provides a durable, maintenance-free traction solution. The differential uses precision helical gears rather than clutch packs, allowing it to operate smoothly and quietly without special lubricants or friction modifiers. Its robust design is suited for a wide range of automotive and performance applications where dependable torque transfer is required.

• Automatic Engagement: Responds automatically to differences in wheel speed and available traction without switches, controls, or driver intervention.
• Optimized Torque Bias: Helps maximize acceleration and improve handling by directing torque toward the wheel with better traction.
• Maintenance-Free Design: Requires no special lubrication or friction modifiers, simplifying installation and long-term service requirements.
• Smooth, Quiet Operation: Helical-gear construction delivers durable and consistent limited-slip performance in forward and reverse.
