🧾 Overview
The Eaton ELocker® Electronic Locking Differential for Dana 44 axles delivers true on-demand traction with the reliability and simplicity of electronic actuation. Designed for both front and rear Dana 44 applications, this ELocker provides a 100% mechanical lock at the flip of a switch, then returns to open differential operation for smooth street driving.
Unlike automatic lockers or air-actuated systems, the Eaton ELocker requires no compressor, air lines, or solenoids. When unlocked, the differential behaves like a factory open unit, preserving steering response, minimizing drivetrain stress, and maintaining predictable handling. When engaged, both axle shafts are locked together, delivering maximum traction for rock crawling, trail riding, towing, and work-truck use.
This version is engineered specifically for Dana 44 axles with 30-spline shafts and 3.73 or numerically lower gear ratios, making it ideal for classic trucks, older Jeeps, and vintage 4x4 applications.
✔ Push-button electronic locking
✔ No air system required
✔ Excellent balance of trail traction and on-road manners
