Product Description

The Eaton 14313-2 ELocker is a high-performance selectable locking differential designed for Jeep Wrangler JL and Jeep Gladiator JT platforms equipped with Dana 44 M220 axles. It allows drivers to switch between open and fully locked differential modes instantly using an electronic dash-mounted control system.

Unlike traditional air lockers, the ELocker uses an electromagnetic engagement system with forged internal gears for increased strength and reliability. This design eliminates the need for air compressors or external pneumatic systems while maintaining precise traction control in demanding off-road environments.

This unit is engineered for serious off-road use including rock crawling, mud, and low-traction terrain where maximum torque distribution is required. It provides OEM-level drivability in open mode and full axle lockup when engaged, making it a versatile upgrade for Jeep performance builds.
