Eaton ELocker4 Differential Performance 40 Spline 4.56 & Up Ratio Dana Super 60

The Eaton ELocker is an electronic, selectable differential designed for drivers that need traction on-demand. At the flip of a dash switch, drivers can go from open to 100-percent locked. A second flip of the switch deactivates the unit to resume normal driving. The direct acting mechanism activates in .14 second to provide 100% instant axle lock, and remains locked in both forward and reverse.
