Eaton Elocker4 Differential 27 Spline 3.73 Ratio Dana 30

Eaton is well-known for making tough drivetrain components, and their ELocker4 differential is a prime example of that expertise. If you're looking to add serious traction to your Jeep Wrangler, Ford Bronco, or International Scout, this selectable locker is built to get you through challenging terrain. It lets you switch from an open differential for normal driving to a fully locked unit with the push of a button, giving you 100-percent traction when you need it most. A second press of the button disengages the locker, returning your vehicle to standard open differential operation.

This ELocker4 features a robust 4-pinion net-forged gear design, which is built for maximum strength and durability, especially important when you're pushing your vehicle hard off-road. The electromagnetic locking mechanism is controlled by a driver-activated push-button system. Eaton includes a locking rocker switch and the necessary wiring harness, making installation more 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.

This differential is designed for Dana 30 axles with 27 spline shafts and is compatible with ring gear and pinion ratios of 3.73 and numerically higher. It's a popular choice for a wide range of vehicles, including many Jeep models like the CJ series and Wranglers, as well as classic Ford Broncos and International Scouts. When you need dependable traction that you can control, the Eaton ELocker4 is a solid option.
