Why choose an Eaton ELocker?

The Eaton ELocker is an electronic, selectable differential designed for drivers that need traction on-demand.


While driving under normal conditions, the ELocker® performs as an open differential. If an obstacle is encountered – a rocky trail, muddy ditch or other challenge – the driver turns on a dash switch to activate the unit. The electromagnetic mechanism then locks, capturing 100% of the available torque and sending it equally to both wheels. A second flip of the switch deactivates the unit to resume normal driving.


ELocker® internal gears are net-forged, providing the strength and durability necessary for off-road and recreational driving. Its electronic control also provides added reliability over similar air-controlled products.


  • Selectable ‘push-button’ operation
  • Positive-electronic locking mechanism
  • Net-forged gears for added strength
  • Validated performance and durability
  • New wiring harness designed for easy installation


  • Provides 100% axle lock on demand
  • Sends all available torque to both wheels upon driver command providing maximum traction to overcome most any challenging terrain.


ELocker units are available for front and rear axles in a variety of applications.
