Detroit NoSPIN Lockers

Eaton’s Detroit NoSPIN is a fully automatic, positive-locking, traction differential designed to replace the internal gear set of the factory or open differential. The NoSPIN locker is renowned for its premium performance, dependable operation and unmatched durability. NoSPIN is a proven performer for heavy duty trucks, off-highway, agricultural, forestry, military, and special equipment vehicles.

The Detroit NoSPIN maximizes traction by delivering 100 percent 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” to permit necessary wheel speed differentiation when negotiating turns, maintaining 100 percent of the powertrain torque to the driving wheel. The NoSPIN is maintenance free and doesn’t require special lubricants or service adjustments. This superior product continues to drive your vehicle even in the event of axle shaft failure.
