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.

Z Automotive Jeep JL/JT Z-Locker Controller Harnesses

Z Automotive Jeep JL/JT Z-Locker controller harnesses are plug-and-play solutions to aftermarket locker integration using factory locker controls on Wrangler JL and Gladiator Rubicons. These simple adapters use watertight connectors, a potted design, and automotive-grade internal components to last in the harsh Jeep undercarriage environment. One end of each adapter plugs into the 4-pin factory harness, providing the required signals to keep the Rubicon locker control logic satisfied. The other end is a 2-pin connector which will output 12 V to engage your E-Locker or Air Locker solenoid. Z Automotive Jeep JL/JT Z-Locker controller harnesses retain the factory locker switches, dash messages, warnings, and will even set off the "service locker" message if your aftermarket locker is faulty or gets disconnected.

Auburn Gear Select-A-Loc Differentials

Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.

SVL Drivetrain Ring and Pinion Gear Sets

SVL Drivetrain ring and pinion gear sets make it easy to find the right ratio for your application. Engineered and manufactured for all makes and ratios, they deliver the ideal blend of coverage, performance, and value. SVL starts their ring and pinion sets with a computer-generated gear summary. From there, the gearing is forged from alloy steel for optimal hardness; then the gears are cut with the utmost accuracy to ensure the smoothest possible ride—and computer-controlled heat-treating results in extra wear resistance. In the final stage of the process, the ring gear is mated to the pinion through gear lapping, which provides ideal meshing of the gearing. You can count on SVL Drivetrain ring and pinion gear sets to fit and function as expected in your automotive application.
