The Eaton ELocker4 is an electronic, selectable differential designed for drivers that need traction on-demand. At the flip of a switch, drivers can go from open to 100-percent locked and back again. The 4 pinion gear design provides added strength and capability for more extreme vehicles, and features the fastest engagement (.14 seconds).


Well designed locker very strong

First, it's from Eaton who is a major supplier to a major auto manufacturer. They only build top quality products. It's the strongest D30 locker out there. It locks up quick and unlocks just as fast - no waiting for air pressure to build up. There are no expensive air pumps to buy.It's the least expensive selectable locker that I know of. It brought my XJ to a new level of offroad performance I didn't think possible. It climbs over virtually everything Moab can throw at it.
