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.\u003c\/p\u003e\u003cp\u003eBuilt 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Engagement:\u003c\/strong\u003e Responds automatically to differences in wheel speed and available traction without switches, controls, or driver intervention.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Torque Bias:\u003c\/strong\u003e Helps maximize acceleration and improve handling by directing torque toward the wheel with better traction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance-Free Design:\u003c\/strong\u003e Requires no special lubrication or friction modifiers, simplifying installation and long-term service requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmooth, Quiet Operation:\u003c\/strong\u003e Helical-gear construction delivers durable and consistent limited-slip performance in forward and reverse.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eKey Product Specifications \u0026amp; Technical Data:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Eaton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family:\u003c\/strong\u003e Detroit Truetrac\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 915A386\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDifferential Type:\u003c\/strong\u003e Helical-gear limited-slip differential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle Application:\u003c\/strong\u003e Rear Dana 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle Spline:\u003c\/strong\u003e 35 spline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle Shaft Diameter:\u003c\/strong\u003e 1.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Gear and Pinion Ratio:\u003c\/strong\u003e 4.56 and up\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eaton Detroit Truetrac limited-slip differential for the specified rear Dana 60 application.
