Eaton ELocker Electronic Locking Differential

The Eaton ELocker is an electronically selectable locking differential engineered for drivers who demand reliable, on-demand traction without sacrificing everyday drivability. Backed by Eaton's decades of drivetrain and torque control engineering expertise, the ELocker product line delivers the best of both worlds — the smooth, open-differential operation drivers expect under normal conditions, and the full locking capability required when challenging terrain demands it.

Under normal driving conditions, the ELocker functions as a conventional open differential, allowing wheels to rotate at different speeds for comfortable cornering and confident highway performance. When the terrain turns demanding — rocky trails, muddy ditches, loose sand, or snow — the driver activates the electromagnetic locking mechanism via a dash-mounted switch, instantly delivering 100% differential lockup and distributing all available torque equally to both wheels. A second press of the switch instantly returns the unit to open-differential operation, with no tools or manual adjustments required.

Key Features:

• Driver-controlled push-button activation — seamless transition from open to fully locked via a simple dash-mounted switch
• 100% differential lockup on demand for maximum traction in mud, sand, snow, rocks, and uneven terrain
• Open differential operation during normal driving for comfortable street manners, predictable handling, and fuel efficiency
• Electromagnetic engagement mechanism — no air lines, vacuum systems, or complex mechanical linkages required
• Net-forged internal gears for maximum strength and long-term durability under demanding off-road and recreational use
• Four-pinion gear design for smooth engagement and validated load capacity across the product line
• Electronic control system delivers added reliability compared to air-actuated locker alternatives
• Direct-fit engineering designed to integrate with OEM axle housings across a wide range of applications
• Virtually maintenance-free design under normal use conditions

Unlike automatic lockers that engage without driver input — or mechanical lockers that remain constantly engaged — the ELocker puts traction control entirely in the driver's hands. The electromagnetic actuation system eliminates the need for an external air supply or vacuum lines, simplifying installation and improving long-term serviceability compared to air-actuated alternatives. Eaton's rigorous engineering standards ensure that every ELocker in the product line is built for demanding torque capacity, consistent engagement reliability, and lasting durability.

Whether the application is overlanding, trail riding, rock crawling, towing, or working in low-traction conditions, the Eaton ELocker delivers a versatile traction solution that performs confidently on and off the pavement.
