What gear ratios is this differential compatible with?

The Eaton ELocker4 differential is designed for Dana 35 axles with a 3.54 gear ratio or any numerically lower ratio. It is not compatible with numerically higher gear ratios.

What is included with the Eaton ELocker4 differential?

The kit includes the ELocker differential unit, a driver-controlled push-button switch for engagement, and the necessary wiring harness for installation. You will need to provide your own tools and potentially other installation hardware.

How does the electronic locker engage and disengage?

The ELocker uses an electromagnetic locking mechanism. You engage it by pressing a button on the included dash switch, which locks the differential for maximum traction. Pressing the button again deactivates the locker, returning the vehicle to normal open differential operation.

Product Details

The Eaton ELocker4 differential features a net-forged, 3-pinion gear design, which means it's built strong for demanding situations. This electronic, selectable differential lets you switch from an open differential to 100-percent locked traction with the simple push of a button on the included dash switch. When you need maximum grip for crawling over obstacles or getting through tough terrain, you can lock it in. Once you're back on the pavement or need to make a tight turn, another press of the button deactivates the locker, returning your vehicle to normal open differential operation.

This ELocker is designed to work reliably in both forward and reverse directions, giving you confidence no matter how you're moving. The electromagnetic locking mechanism is known for its dependability, making it a popular choice for drivers who need traction when they need it most. The kit includes the locker itself, a driver-controlled push-button switch, and the necessary wiring harness to get it installed. This differential is a solid option for a wide range of vehicles, including the Ford Explorer, Jeep Cherokee, and Jeep Wrangler, among others.

When you're planning your installation, remember that this unit is designed for Dana 35 axles with 3.54 and numerically lower gear ratios, and it requires 1.18-inch axle shafts. It's a significant upgrade for off-road performance, providing the ultimate in on-demand traction. Be sure to consult the manufacturer's installation instructions for specific details regarding your vehicle's axle setup.
