Product Description

The Eaton 915A387 Detroit Truetrac is a high-performance limited slip differential engineered for Dana 60 axles with 35-spline shafts and 4.10 & down gear ratios. Its advanced helical gear design automatically biases torque to the wheel with the most traction, improving cornering, acceleration, and control without requiring driver intervention. Unlike traditional clutch-based limited slip units, the Truetrac design is maintenance-free and operates quietly, making it ideal for daily driving, off-road adventures, and heavy-duty towing applications.

Built for strength and reliability, this differential suits a variety of truck and SUV platforms that use the Dana 60 axle. Whether you're upgrading performance, enhancing traction in adverse conditions, or replacing a worn unit, the 915A387 delivers smooth torque distribution and superior durability. Be sure to confirm gear ratio and spline count compatibility before installation.
