Auburn Gear ECTED Electrically Activated Lockers for Dana 44 with 30-Splines & 3.92 Gear Ratio and Numerically Higher
The ECTED (Electronically Controlled Traction Enhancing Differential) is exclusively controlled by electrical current to the coil. The ECTED unit does not require complicated external pneumatic or hydraulic connections that are vulnerable to failure. In fact, the ECTED has been designed to fit without modification except for a small wire entrance hole. When activated, the current to the coil creates a magnetic field that compresses the clutch pack that engages the locker. Since the ECTED is electronically controlled, it is capable of instantaneous engagement and can be deactivated at any point in time with the flip of a switch inside the vehicle. The ECTED defaults to a limited slip type differential that's suitable for daily driving and provides greater traction on moderate off road situations. Locker comes with wiring harness and switch. Bearings and seals sold separately. Not for Wrangler JK Models.
