Eaton ELocker4 Differential Dana 70 Performance 40 Spline 4.10 & Down Ratio

Eaton is known for making robust drivetrain components, and their ELocker4 differential is a prime example of that expertise. If you're looking to add serious traction control to your vehicle, especially for off-road use or challenging conditions, this selectable differential is a solid choice. It allows you to switch from an open differential, which provides normal driving characteristics, to a fully locked axle with the simple flip of a dash-mounted switch. This means you get 100-percent instant traction when you need it, whether you're crawling over rocks or navigating slippery terrain.

What sets this ELocker apart is its direct-acting electromagnetic mechanism. It engages in just 0.14 seconds, providing immediate and complete axle lock that holds firm in both forward and reverse. The design features a 4-pinion net-forged gear setup, built for maximum strength and durability to handle demanding situations. This isn't just about getting unstuck; it's about having reliable control when you need it most. The package includes Eaton's NGR locking rocker switch and a complete wiring harness, making installation more straightforward.

This differential is designed for Dana 70 axles with 40 spline axle shafts and is compatible with ring and pinion gear ratios of 4.10 and numerically lower (like 4.56, 4.88, etc.). The 1.50-inch axle shaft diameter and 10.5-inch ring gear diameter are key specifications to ensure it's the right fit for your rear axle setup. When you need to go from open-road cruising to locked-in performance, this unit offers dependable, on-demand traction.
