Its automatic operation transfers torque to the wheel with greater traction without requiring driver input, helping maintain forward momentum when grip is reduced.\u003c\/p\u003e\n\u003cp\u003ePart number eat913A477 is engineered for rear axle applications using a 9.75-inch housing, 34-spline axle configuration, and 1.37-inch axle shaft diameter. The Detroit Truetrac uses precision helical gears rather than clutch packs, providing smooth, quiet, and consistent performance in both forward and reverse. Its maintenance-free design does not require special lubrication or friction modifiers, simplifying installation and long-term service.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Rear 9.75-inch axle applications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAxle Configuration:\u003c\/strong\u003e 34-spline differential\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAxle Shaft Diameter:\u003c\/strong\u003e 1.37 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGear Type:\u003c\/strong\u003e Helical-gear limited-slip differential\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGear Ratio Compatibility:\u003c\/strong\u003e All ratios\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Direction:\u003c\/strong\u003e Forward and reverse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEngagement:\u003c\/strong\u003e Automatic torque-biasing operation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLubrication:\u003c\/strong\u003e No special lubricant or friction modifier required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Eaton Detroit Truetrac is suitable for many vehicle types and is built to deliver dependable traction with durable, low-maintenance operation.
