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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eaton Detroit Truetrac limited-slip differential for the specified rear Dana 44 application.
