Z Automotive Jeep JL/JT Z-Locker OEM Controller Harnesses

The locker sensor in Wrangler JL and Gladiator Rubicons have started to become problematic. When they fail, it usually starts out as a blinking locker indicator on the dash, which then ends up in a "service axle locker" message and the lockers will no longer engage. The repair would normally be to replace the sensor or the locker assembly, but they are not available, so the entire axle assembly needs replaced. Developed in a partnership with Americas Most Wanted 4X4, Z Automotive Jeep JL/JT Z-Locker OEM controller harnesses provide a simple fix for faulty OEM axle locker. Each harness will bypass the problematic sensor, allowing the locker to operate without the position sensor and provide the proper feedback to the Jeep's computers to keep the system operational without any errors or warnings. You get fully functioning lockers with no side effects. Installation is simple and they will not harm the Jeep's computers as they use the same signaling that it expects from the sensor. The connectors are the same ones used by Jeep and are watertight.

Designed for specific front and rear axles of several popular trucks and Jeeps, these heavy-duty, high-strength nodular iron covers have a fluid level port or ports placed at the correct level to meet factory specifications (for front or rear), eliminating the need to guess on the oil level or use a dipstick to figure out the correct amount of oil.
