Part EAT917A740 is engineered to improve traction, acceleration, and handling by automatically transferring torque to the wheel with greater grip. It is designed for all axle gear ratios and works in both forward and reverse.\u003c\/p\u003e\u003cp\u003eUnlike clutch-style limited-slip differentials, the Detroit Truetrac uses a gear-driven design that does not require special lubrication or friction modifiers. This construction provides smooth, quiet, and durable operation for daily driving, towing, and demanding road conditions. Optimized torque bias ratios help maintain confident power delivery without requiring manual engagement or driver input.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Designed for 2020-2021 GMC Sierra 2500 HD models with the 6.6L diesel engine, rear 31-spline axles, and the specified AAM 11.5-inch rear axle configuration.
