Eaton ELocker4 Differential Dana 70 35 Spline 4.56 & Up Ratio

When you're tackling challenging off-road trails or need extra grip in slippery conditions, having traction on demand makes all the difference. The Eaton ELocker4 is a selectable electronic differential designed for situations where you need to go from open differential performance to a 100-percent locked axle instantly. This unit fits a wide range of vehicles, including many Chevrolet Astro vans, Dodge B-series vans, and Ford F-350 trucks, among many others, making it a versatile upgrade for many applications.

At the heart of the ELocker4 is a robust 4-pinion net-forged gear design, built for maximum strength and durability when you need it most. When you decide to engage it, a simple flip of the included dash switch activates the electromagnetic locking mechanism in just 0.14 seconds. This provides instant, 100-percent axle lock that remains engaged in both forward and reverse, giving you unwavering traction. When you're back on the pavement or don't need the locked performance, another flip of the switch disengages the unit, returning your vehicle to normal open differential operation. This direct-acting system is known for its reliability and straightforward operation, offering a dependable solution for on-demand traction.

This kit comes complete with the Eaton NGR locking rocker switch and a wiring harness, so you have the essential components to get the locker installed and operational. It's designed for Dana 70 axles with 35-spline axles and is compatible with 4.56 and numerically lower gear ratios. Ensure you have the correct ring gear diameter (10.5 inches) and axle shaft diameter (1.50 inches) for proper fitment.
