Product Description

The Eaton 14216-1 ELocker is an electronically controlled locking differential designed for the rear 8.4-inch axle equipped with 30-spline shafts found in many Toyota Tacoma, Tundra, Sequoia, and T100 models. It allows the driver to switch between an open differential for normal driving and full lock for situations demanding maximum traction, such as off-road, mud, snow, or when towing heavy loads.

This unit is built with net-forged gears, designed to handle higher torque loads while maintaining durability and reliability. Installation requires confirming your rear housing is the 8.4-inch ring gear design with a 12 bolt ring gear, and that axle shafts are 30-spline. Matching gear ratios are required, but Eaton indicates all ratios are compatible. Wiring provisions are included to connect the rocker switch. Fitment is confirmed through **2016**; years beyond 2016 are unverified.
