Eaton Torque Control Products 19819-020 ELocker Electronic Locking Differential Dana - 30 30-Spline

The Eaton ELocker 19819-020 is an electronic, selectable locking differential designed for Dana Super 30 axles with 30-spline axle shafts and gear ratios of 3.73 and up. This advanced differential gives drivers complete control over traction with simple push-button activation from the dashboard.

How It Works:

Under normal driving conditions, the ELocker operates as a standard open differential for comfortable daily driving, optimal fuel economy, and even tire wear. When challenging terrain is encountered—whether rocky trails, muddy conditions, or steep inclines—a flip of the dash-mounted switch activates the electromagnetic locking mechanism. Once engaged, the ELocker sends 100% of available torque equally to both wheels, providing maximum traction when you need it most. A second press of the switch instantly returns the unit to open differential operation.

Key Features:

• Electronic activation via dash-mounted rocker switch (included with wiring harness)
• Net-forged internal gears provide superior strength and durability compared to standard cut gears
• 4-pinion gear design handles increased driveline torque from modern vehicles
• Electromagnetic control offers greater reliability than air-actuated alternatives
• Designed specifically for Dana 30 front axles in 4WD applications
• 30-spline configuration for 1.16-inch diameter axle shafts
• Compatible with gear ratios of 3.73:1 and numerically higher

Installation Requirements:

Requires carrier bearings LM102949, bearing races LM102911, and outboard shim kit (sold separately). Professional installation recommended for proper setup and optimal performance.

The Eaton ELocker combines the everyday drivability of an open differential with on-demand full-locker capability, making it ideal for off-road enthusiasts, rock crawlers, and anyone who needs reliable traction performance without compromising daily driving comfort.
