Specs
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.

Eaton E-Locker FAQ
What vehicles is the Eaton ELocker EAT14216-1 compatible with?
This model is designed specifically for Toyota vehicles with 8.4-inch ring gear, 30-spline axles, and 12-bolt ring gear setups. Common compatible models include the Toyota Tacoma, Tundra, Sequoia, and T-100.
How does the Eaton ELocker differ from a standard limited-slip differential?
The Eaton ELocker is an electronically selectable locker that provides 100% locking of both axle shafts when engaged, offering full traction. In contrast, a limited-slip differential provides partial traction improvement but never fully locks the axle shafts.
Can I install the Eaton ELocker myself, or do I need professional help?
While a skilled DIYer with experience in axle work can install it, the process involves disassembling the axle, drilling for wiring, and precise reassembly. Professional installation is recommended to avoid damage and ensure proper function.
Do I need any special gear oil for the Eaton ELocker?
A good-quality petroleum-based gear oil is recommended. Synthetic oils can also be used, and friction modifiers are optional but usually not necessary.
How do I operate the Eaton ELocker once installed?
Operation is via a dash-mounted switch. Press once to engage (lock) the differential and again to disengage (unlock). It’s best to engage at low speeds (under 5 mph) and low wheel speed difference to prevent damage.
Will the Eaton ELocker affect normal driving on pavement?
When disengaged, the differential behaves like an open diff, allowing normal driving. When engaged, it locks the axle, which can cause some driveline binding and tire wear if used on high-traction surfaces for extended periods.
Is the Eaton ELocker maintenance-free?
Yes, it is designed to be maintenance-free under normal use. However, if necessary, the unit can be serviced or rebuilt.
What happens if I forget to disengage the locker on-road?
Engaging the locker on high-traction surfaces and higher speeds can cause drivetrain binding, accelerated tire wear, and potential damage. Always disengage when not needed.
Does the Eaton ELocker require an air compressor or other external systems?
No, the Eaton ELocker is electronically operated and does not require an air compressor like some other lockers.
Will the Eaton ELocker improve my vehicle's towing capabilities?
Yes, it provides better traction under heavy load or uneven terrain, which can improve towing performance by preventing wheel slip.
