Eaton Posi Performance Differentials

4.68 out of 5 stars 104 Customer Reviews

Big torque doesn't have to mean big traction problems. Eaton Posi Performance differentials combine carbon friction discs with precision-forged gears to give you great traction, even under higher torque loads. Plus, the carbon friction discs produce smooth, quiet performance for the life of your vehicle.
