The Eaton Detroit Truetrac Differential is a helical-gear limited-slip differential designed to improve wheel traction, acceleration, and handling in a wide range of vehicles. Part Number EAT913A589 is engineered for rear Dana 44 applications with 30-spline axle shafts and a 3.73-and-down ring gear and pinion ratio. Its automatic operation helps transfer torque to the wheel with greater traction without requiring driver input.

The Detroit Truetrac uses durable helical gearing for smooth, quiet, and maintenance-free performance in both forward and reverse. It engages automatically when needed and does not require special lubrication or friction modifiers, simplifying installation and ongoing service. Optimized torque bias characteristics help enhance vehicle control and traction during acceleration, cornering, and changing road conditions.

What's Included: One Eaton Detroit Truetrac limited-slip differential for the specified rear Dana 44 application. Verify axle configuration, spline count, axle shaft diameter, and gear ratio before ordering to ensure proper fitment. This differential is intended for compatible automotive applications and is not supplied with additional installation hardware or lubricants unless otherwise specified by the manufacturer.

Features:

• Automatic Engagement: Operates automatically to direct torque toward the wheel with better traction without requiring manual activation.
• Optimized Torque Bias: Helps improve acceleration, handling, and vehicle traction during changing driving conditions.
• Maintenance-Free Design: Requires no special lubrication or friction modifiers when used with the appropriate differential lubricant.
• Smooth and Quiet Operation: Helical-gear construction provides durable performance in both forward and reverse.
