The Eaton ELocker Differential EAT14232-1 is a selectable electronic locking differential designed for Toyota Tundra drivers who need traction on demand. With driver-controlled push-button operation, the differential can switch from open operation to fully locked traction at the flip of a dash-mounted switch. A second press disengages the locker for smooth, conventional driving on paved roads.

Built for demanding off-road and heavy-duty applications, this Eaton ELocker features a four-pinion net-forged gear design engineered for strength and durability. Its electromagnetic locking mechanism works in both forward and reverse, helping provide controlled traction when one wheel begins to lose grip. The included Eaton NGR locking rocker switch and wiring harness support a complete installation and convenient in-cab operation.

This rear differential is designed for Toyota Tundra applications using a 10.5-inch axle, 36-spline axle shafts, and a 1.45-inch axle shaft diameter. It fits select 2003 and 2005–2013 Toyota Tundra models; verify the vehicle’s axle configuration, spline count, and application before installation. The Eaton ELocker combines selectable operation with rugged internal components for drivers who want reliable traction without sacrificing normal street manners.
