Its automatic operation transfers torque smoothly to the wheel with greater available traction, helping maintain forward momentum without driver intervention. The differential operates in both forward and reverse and is suitable for non-disconnect axle applications.\u003c\/p\u003e\u003cp\u003eBuilt for dependable street and off-road performance, the Eaton Detroit Truetrac uses durable helical gearing for smooth, quiet operation and consistent engagement. Its maintenance-free design does not require special lubrication or friction modifiers, simplifying installation and long-term service. Optimized torque-bias characteristics help enhance vehicle control while preserving predictable driving behavior during changing traction conditions.\u003c\/p\u003e\u003cp\u003eThis Detroit Truetrac differential is configured for 30-spline axle shafts with a 1.31-inch axle shaft diameter and ring gear and pinion ratios of 3.92 and higher. It is intended for front Dana 44 applications that do not use axle disconnect systems. Verify axle configuration, spline count, ratio compatibility, and available clearance before installation. Professional installation is recommended to ensure proper setup and gear engagement.\u003c\/p\u003e\u003ch3\u003eKey Product Specifications and Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Eaton\u003c\/li\u003e\n\u003cli\u003eProduct Line: Detroit Truetrac\u003c\/li\u003e\n\u003cli\u003ePart Number: EAT913A592\u003c\/li\u003e\n\u003cli\u003eDifferential Type: Helical-gear limited slip\u003c\/li\u003e\n\u003cli\u003eAxle Application: Front Dana 44\u003c\/li\u003e\n\u003cli\u003eAxle Shaft Configuration: 30 spline\u003c\/li\u003e\n\u003cli\u003eAxle Shaft Diameter: 1.31 inches\u003c\/li\u003e\n\u003cli\u003eCompatible Ring Gear and Pinion Ratio: 3.92 and higher\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOne Eaton Detroit Truetrac limited-slip differential\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eFitment data should be verified against the vehicle's axle model, spline count, gear ratio, and non-disconnect configuration before purchase.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTorque Bias Performance: Optimized torque-bias characteristics help improve acceleration, traction, and handling.\u003c\/li\u003e\n\u003cli\u003eAutomatic Engagement: Transfers torque automatically to the wheel with better traction without requiring driver input.\u003c\/li\u003e\n\u003cli\u003eSmooth Operation: Helical gearing provides quiet, predictable performance in forward and reverse.\u003c\/li\u003e\n\u003cli\u003eMaintenance-Free Design: Requires no special lubrication or friction modifiers under the recommended service conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Unknown\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":67646952702204,"sku":"913A592","price":735.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/b99887b8556e01aff2bb11ec03f6c212_99526c19-7de9-49af-858f-5c073cef1242.jpg?v=1791183592","url":"https:\/\/diycustoms.store\/products\/eaton-detroit-truetrac-differential-30-spline-3-92-and-up-ratio-front-dana-44-eat913a592","provider":"diycustoms.store","version":"1.0","type":"link"}
