Eaton ELocker4 Differential 30 Spline Toyota FJ/4Runner/Tacoma/Land Cruiser 120/150

Eaton is well-known for making robust drivetrain components, and their ELocker4 differential is a prime example of that expertise. If you're looking to significantly improve your Toyota's off-road capability, especially in challenging terrain, this selectable differential is a serious upgrade. It allows you to switch from a standard open differential to a fully locked 100-percent engagement with the simple flip of a dash-mounted switch. This means you get exceptional traction when you need it, like crawling over rocks or navigating deep mud, and can disengage it for normal, comfortable driving on the street.

What sets the ELocker4 apart is its reliability and strength. It features a 4-pinion net-forged gear design, which is built for maximum strength and durability, especially important when you're putting your vehicle to the test. The electromagnetic locking mechanism is controlled by a push-button switch, and Eaton includes the necessary NGR locking rocker switch and wiring harness to get you set up. This unit works effectively in both forward and reverse, giving you consistent performance no matter which way you're moving. It's designed to fit axles with 30 splines and is compatible with ring gear pinion ratios of 3.73 and down, making it a solid choice for many Toyota 4x4s.

When installing this differential, it's important to note that it's designed for axles with 1.31-inch axle shaft diameter and an 8.0-inch ring gear. Because this is a significant drivetrain modification, we always recommend consulting the manufacturer's installation instructions or a qualified mechanic to ensure it's fitted correctly. This differential is a popular choice for those who frequently venture off-road and demand dependable traction when they need it most.
