Eaton Torque Control Products 19817-020 ELocker Electronic Locking Differential Dana - 30 27-Spline

The Eaton ELocker 19817-020 is an electronically selectable locking differential designed for Dana 30 front axles with 27-spline axle shafts and gear ratios of 3.54 and numerically lower (3.54, 3.31, 3.07, etc.). This advanced differential combines the smooth operation of an open differential for everyday driving with the traction control of a full locker when you need it most.

Key Features:

• Electromagnetic locking mechanism activates with a simple dashboard-mounted switch
• Functions as an open differential under normal driving conditions for improved fuel economy and tire life
• When locked, delivers 100% of available torque equally to both wheels for maximum traction
• Precision net-forged internal gears provide superior strength and durability compared to standard cut gears
• Four-pinion gear design handles higher driveline torques
• Includes Eaton NGR locking rocker switch and wiring harness
• 1.16-inch axle shaft diameter compatibility

Installation Requirements:

• Requires carrier bearings LM102949 (2 required) and races LM102911 (2 required)
• SKSS10 shim kit required for proper installation
• Bearings and installation kit sold separately

Ideal for off-road enthusiasts, rock crawlers, and anyone who demands on-command traction control. The electronic operation provides superior reliability compared to air-actuated lockers, and the smooth power transfer is typically unnoticeable to the driver even in front-wheel applications.
