The Eaton ELocker is an electronic, driver-selectable locking differential. A dash-mounted switch lets the driver run fully open for normal street manners, then lock the axle 100 percent on demand for maximum traction. Net-forged internal gears make it strong and dependable. Installation uses a wiring kit with dash switch, relay, solenoid, and harness plus the axle-specific stator and armature hardware.
