Operation

Under normal conditions, the ELocker performs as an open differential. When an obstacle is encountered, a rocky trail, muddy ditch or other challenge, the driver presses a dashboard switch. The electromagnetic mechanism then locks, sending 100% of the available torque to both wheels equally. A second press of the switch deactivates the unit to resume normal driving.

Performance

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.

Lubrication

Most gear oils are sufficient: a quality, petroleum-mineral based oil is recommended. Synthetic oils and friction modifiers can also be used, but are not necessary. In cold weather conditions, a lower viscosity gear oil (equivalent to API GL-5 75W-90) is recommended.

Features

• Driver controlled push-button operation
• Positive-electronic locking mechanism
• Net-forged gears for maximum strength and durability
• Sends all available torque to both wheels equally upon driver command, providing maximum traction to overcome challenging terrain
• Eaton NGR locking rocker switch and wiring harness included
