Eaton has a proven track record of producing the most effective and dependable traction differentials in the world. Truetrac's patented design of parallel axis, planetary helical gears, provides a smooth and quiet automatic division of torque. Power transfer is so smooth, it is typically unnoticed by the driver, even in front wheel drive axles. Although Truetracs offer the highest bias ratio in the forward direction, they also exhibit a slightly reduced bias ratio in the reverse direction or during engine braking. The bias performance of the Truetrac complements and enhances brake-based traction control systems. Under normal driving conditions, Truetrac performs like an open differential. On wet, muddy, icy or loose terrain, imbalanced gear forces automatically transfer power to the wheel with the highest traction. The Truetrac limited-slip differential responds instantly to torque feedback, providing needed traction, anytime, at any speed. Truetrac differentials are engineered to work efficiently in front and rear axles and transfer cases. Designs exist for C-clip, full-float, semi-float, and snap-ring style axle configurations. Proven design, low cost and effective performance all make the Truetrac limited-slip differential the ideal choice for a wide variety of vehicle applications, including road racing, off-road competition, emergency vehicles, motor homes and commercial trucks.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"component kaoxa-product-detail-features col-12\"\u003e\n\u003cdiv class=\"component-content\"\u003e\n\u003cdiv class=\"tabbable populated\"\u003e\n\u003cdiv class=\"product-detail-features\"\u003e\n\u003ch1\u003eFeatures \u0026amp; Benefits\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli class=\"feature\"\u003ePatented Design Of Parallel Axis, Planetary Helical Gears - Provides A Smooth And Quiet Automatic Division Of Torque\u003c\/li\u003e\n\u003cli class=\"feature\"\u003eImproved Traction Relative To Other Rear-Wheel And Four-Wheel-Drive Vehicles\u003c\/li\u003e\n\u003cli class=\"feature\"\u003eProven Design, Low Cost And Effective Performance All Make The Truetrac Limited-Slip Differential The Ideal Choice For A Wide Variety Of Vehicle Applications\u003c\/li\u003e\n\u003cli class=\"feature\"\u003eLimits Wheel Spin-Out And Improves Handling\u003c\/li\u003e\n\u003cli class=\"feature\"\u003eMost Designs Are Engineered To Transfer Up To 3.5 Times More Torque To High Traction Wheel\u003c\/li\u003e\n\u003cli class=\"feature\"\u003eLimited-Slip Differential Responds Instantly To Torque Feedback, Providing Needed Traction, Anytime, At Any Speed\u003c\/li\u003e\n\u003cli class=\"feature\"\u003eLimited 1 Year Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eAttributes\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan class=\"attribute-name\"\u003eAxle Model: \u003c\/span\u003e\u003cspan class=\"attribute-value\"\u003eGM 8.5 Inch\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"attribute-name\"\u003eType: \u003c\/span\u003e\u003cspan class=\"attribute-value\"\u003eLimited Slip\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"attribute-name\"\u003eSpline Count: \u003c\/span\u003e\u003cspan class=\"attribute-value\"\u003e28\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"attribute-name\"\u003eGear Ratio: \u003c\/span\u003e\u003cspan class=\"attribute-value\"\u003e2.73 And Up\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"attribute-name\"\u003eMaterial: \u003c\/span\u003e\u003cspan class=\"attribute-value\"\u003eSteel\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"attribute-name\"\u003eJournal Size: \u003c\/span\u003e\u003cspan class=\"attribute-value\"\u003e1.20 Inch\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-3\"\u003eEATON TCPD\u003c\/div\u003e\n\u003cdiv class=\"col-1\"\u003eE36\u003c\/div\u003e\n\u003cdiv class=\"col-lg\"\u003eLimited Slip Differentials, Service Kits for Limited Slip Differentials\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cspan\u003eWarranty Return Policy:\u003c\/span\u003e Please contact KAO\/NTP-STAG\/SeaWide customer service at 1-800-521-9999 for warranty information and return entry.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-3\"\u003eTRAC TECH\u003c\/div\u003e\n\u003cdiv class=\"col-1\"\u003eT15\u003c\/div\u003e\n\u003cdiv class=\"col-lg\"\u003ePosi-Traction Differentials, Detroit Lockers\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cspan\u003eWarranty Return Policy:\u003c\/span\u003e This supplier has been discontinued.
