Eaton ELocker4 Differential 30 Spline 3.73 & Up Ratio Dana 30/30S

If you're looking to get serious traction when you need it most, the Eaton ELocker4 differential is a solid choice. This electronic, selectable differential lets you switch from an open differential to a fully locked one with the flip of a dash-mounted switch. It's designed for a range of popular Jeep models, including the CJ7, Cherokee, and Wrangler, and works with Dana 30 axles that have 30 spline shafts and a 3.73 or numerically higher gear ratio. This means you can tackle tough off-road trails or slippery conditions with confidence, knowing you can engage full lock when the situation demands it, and then disengage it for normal street driving.

What sets the ELocker4 apart is its reliability and strength. It features a 4-pinion net-forged gear design, which means the gears are built for maximum strength and durability, handling the stresses of being fully locked. The electromagnetic locking mechanism is known for being one of the most dependable on-demand systems available. You get driver-controlled, push-button operation, and the unit locks securely in both forward and reverse directions. This is a well-built differential that's made to perform when you need it most, giving you that crucial advantage when you're off the beaten path.

When you install the Eaton ELocker4, you'll receive the differential itself, along with Eaton's NGR locking rocker switch and the necessary wiring harness to get it hooked up. This makes for a more complete installation package. Remember to consult the manufacturer's installation instructions for specific details on fitting this to your Dana 30 axle, especially regarding the 3.73 and up gear ratio requirement and the 30 spline count.
