Eaton ELocker Differential Dana 44 Front 30-Spline 3.73-and-Down Ratio EAT19977-010

The Eaton ELocker is an electronic, selectable differential designed for drivers that need traction on-demand. At the flip of a dash switch, drivers can go from open to 100-percent locked. A second flip of the switch deactivates the unit to resume normal driving. The ELocker is the most reliable on-demand differential, featuring selectable operation and net-forged gears for added strength.

The Eaton ELocker Differential provides selectable traction for Dana 44 front axle applications requiring dependable on-demand locking performance. With the included Eaton NGR locking rocker switch, drivers can switch from open differential operation to 100-percent locked traction at the push of a button. Deactivating the switch returns the differential to normal open operation for improved drivability during everyday road use.

Built with an electromagnetic locking system and a 4-pinion net-forged gear design, the Eaton ELocker is engineered for strength, durability, and consistent engagement. The differential operates in both forward and reverse, making it well suited for off-road driving, uneven terrain, and situations where additional traction is needed. Its 30-spline configuration, 1.31-inch axle shaft compatibility, and 3.73-and-down ring gear and pinion ratio specification support precise axle matching.
