Product Description

The Eaton 19818-020 ELocker is a high-performance selectable locking differential engineered for Dana 30 front axles with a 27-spline, 1.16-inch shaft, and 7.2-inch ring gear. Designed for gear ratios of 3.73 and higher, this unit installs in front applications and gives you the ability to toggle between open differential behavior and full locking for maximum traction. Ideal for off-road, towing, and severe duty use, it includes net-forged gears, a durable steel case, and electronic activation via included switch and wiring.

Fitment spans many classic and modern 4x4 applications: Jeep Wranglers (JK & others), older Ford, Chevy/GMC, and IHC/Scout trucks, vans, and SUVs that were built with Dana 30 front axles and meet the ratio/spline requirements. Be sure your vehicle's axle is a Dana 30, has 27 splines, uses a 3.73 or numerically higher gear set, and that it is not part of incompatible systems such as Jeep Quadra-Drive II. If all criteria match, this ELocker offers smooth, reliable on-demand locking performance without the downsides of full-time lockers.
