The Eaton ELocker Differential EAT14216-1 is an electronic, selectable rear differential designed for drivers who need controlled traction on demand. With the push of a dash-mounted switch, the differential transitions from open operation to fully locked engagement, helping both drive wheels maintain traction in challenging terrain. A second push disengages the locker for smooth, conventional driving on paved roads.

Built for Toyota applications using an 8.4-inch rear axle, this Eaton ELocker features 30-spline compatibility and supports axle shafts with a 1.31-inch diameter. Its electromagnetic locking mechanism operates in both forward and reverse, while the four-pinion net-forged gear design provides strength and durability for demanding off-road and utility use. The Eaton NGR locking rocker switch and wiring harness are included for a complete selectable-locker installation.

Designed for reliable on-demand performance, the Eaton ELocker EAT14216-1 gives drivers direct control over when additional traction is available without requiring permanent lockup. Confirm axle configuration, spline count, gear ratio, and application compatibility before installation. This differential is listed for selected Toyota Tacoma and Sequoia applications, including 2001 through 2005 and 2014 model-year fitments where equipped with the matching axle assembly.
