    The Eaton ELocker is an electronic, driver-selectable locking differential. A dash-mounted switch toggles between fully open operation for the street and 100% lock for maximum traction on demand. Net-forged internal gears make it strong and dependable, and installation uses a wiring kit (dash switch, relay, solenoid, harness) plus the axle-specific stator and armature hardware. It is built for the Dana 44 axle in a 30-spline, 3.73 and down fitment.
