What gear ratios is this differential compatible with?

This Eaton ELocker4 differential is designed for Dana 30 axles with 3.54 gear ratios and numerically lower (numerically smaller, e.g., 3.55, 3.73, 4.10). Always confirm your vehicle's specific gear ratio before purchasing.

What is included with the Eaton ELocker4?

The ELocker4 comes with the differential unit itself, an Eaton NGR locking rocker switch, and a complete wiring harness to facilitate installation.

How does the selectable locker work?

The ELocker4 uses an electromagnetic system. When you flip the dash-mounted switch, it engages the locker, forcing both wheels on the axle to turn at the same speed. Flipping the switch again disengages the locker, returning the differential to its normal open state.

Product Details

When you're heading off-road and need serious traction, the Eaton ELocker4 differential is designed to get you there. This selectable differential lets you switch from an open diff for normal driving to a fully locked unit with the push of a button. It's built for vehicles like the Jeep Wrangler, Ford Bronco, and International Scout II, giving you the confidence to tackle tough terrain.

The ELocker4 features a robust 4-pinion net-forged gear design, which means it's built strong for durability when you need it most. The electromagnetic locking mechanism is reliable and works in both forward and reverse. You get complete control over when you engage the locker, allowing you to switch back to open differential operation for easier steering on hard surfaces. This unit is set up for a 3.54 gear ratio and fits Dana 30 axles with 27-spline shafts.

Included with the ELocker4 is Eaton's NGR locking rocker switch and a complete wiring harness, making installation more straightforward. This is a popular choice for off-roaders who want the best of both worlds: an open differential for daily driving and a locked differential for maximum grip when the trail gets challenging.
