Z Locker OEM - Repair Module for Defective Limited Slip Differential Sensor

Developed in collaboration with America's Most Wanted 4X4.

The lock sensor in the Wrangler JL and Gladiator Rubicons has started to become problematic. When it fails, this usually starts with a flashing loose indicator on the dashboard, which then ends in a "service axle loose" message. Once the limited slip differential system is in this fault state, the locks will no longer engage.

The repair would normally be to replace the sensor, but the part is not available separately. The next best solution would be to replace the axle lock, but this is also not available. The current solution is to replace the entire axle assembly. However, since this is a very common problem, these parts are on backorder nationwide.

The Z-Locker OEM solves this problem. It bypasses the problematic sensor and allows the locking mechanism to operate without the position sensor, while still providing the proper feedback to the Jeep's ECUs to keep the system operational without errors or warnings. With the Z-Locker OEM, full functionality of the system is restored.

Installation is simple: unplug the lock and connect the Z-Locker OEM between the axle and the Jeep wiring harness. This can be done in seconds and without tools. The Jeep's ECU is not affected - it uses the same signals it expects from the sensor. The connectors are the same as those used by Jeep and are waterproof.

The package contains a Z-Locker OEM to repair a defective axle lock.
