Eaton ELocker4 Differential 36 Spline 36-Spline Toyota Tundra 10.5in

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 Tundra's traction, especially when you're off the beaten path or dealing with challenging terrain, this selectable differential is a solid choice. It allows you to switch from an open differential, which is great for normal driving, to a fully locked 100-percent differential with the simple flip of a dash-mounted switch. This means you get maximum grip exactly when you need it, and can easily disengage it for smooth road manners.

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, ensuring it can handle the demands of serious off-roading. The electromagnetic locking mechanism is controlled by a push-button, making operation straightforward. This is considered one of the most reliable on-demand differentials available, and it works effectively whether you're moving forward or in reverse. The kit comes complete with Eaton's NGR locking rocker switch and a wiring harness, so you have the essential components to get it installed and running.

Installing a selectable locker like this is a significant upgrade for your Tundra, especially if you frequently encounter situations where traction is limited. It's designed to fit rear axles with a 10.5-inch ring gear and 36-spline axle shafts, which is verified for your 2000-2021 Toyota Tundra. While the installation involves opening up the differential housing, the selectable nature means you don't have to compromise on-road comfort for off-road capability.
