Eaton Detroit No-Spin Differential 36 Spline 1.84in Axle Shaft Diameter Rear Dana S135 - 250SL166

NoSPIN maximizes traction by delivering 100% of the torque and power to both drive wheels. It is engineered to keep both wheels in a constant drive mode, yet has the ability to automatically 'unlock' during vehicle turning to permit necessary wheel speed differentiation. The NoSPIN is 'trouble free' and does not require special lubricants or service adjustments.
