Eaton E Locker Electric Locking Differential

Eaton ELocker – The Electric Locking Differential

Now Available for Toyota and Lexus!

The Eaton ELocker is an electronically actuated locking differential that allows the driver to switch from a fully open differential to a 100% locked unit at the flip of a switch. That means the vehicle will perform and corner smoothly on the highway and perform like a spool when actuated, with 100% torque to both wheels equally. ELockers are ideal for daily driven trucks and 4×4’s as well as extreme competition vehicles.

We have an extensive inventory of Eaton ELockers for GM, Ford, Dodge, Toyota and more. This means your Eaton ELocker will usually ship the same day, as long as you call before 4PM PST.

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.
