Crown Automotive Direct-Fit Axle Shaft Assemblies
If it weren't for axles, the wheels on your vehicle wouldn't be moving anywhere. When those all-important parts twist, break, or have other difficulties, simply replace them with Crown Automotive direct-fit axle shaft assemblies. These assemblies are available for numerous axle types, such as CV-style, C-clip, front inner and outer, and bolt-in. While some replacement axles use hardened 4340 chromoly shafts, most are designed and steel-built to OEM specs for reliability and fitment. Each axle is engineered for its particular location and differential. Crown direct-fit assemblies cover many models of vehicles.

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.

ARB Air Locker Differentials
A 4x4 and traction go hand-in-hand; however, standard (open) differentials allow each wheel to turn independently to eliminate binding in turns. Off-road, this becomes a problem as engine power takes the path of least resistance—to the wheel with little or no traction. Limited slip differentials offer some improvement, but too often the slipping is not "limited" enough to maintain forward progress. Automatic locking differentials also have disadvantages; noisy when disengaging, they can also upset on-highway driving characteristics. Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ a 12 V ARB air compressor (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential. When activated, the Air Locker prevents the differential gears from rotating and the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional open differential. ARB Air Lockers are available in over 100 configurations for a wide range of vehicles and can be installed in both front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required, apart from those necessary for fitting a standard differential. ARB also offers three compressor models suitable for Air Locker operation, two of which can be used to inflate tires and operate other equipment. Additional features of ARB Air Lockers include: * Vastly improved traction means less reliance on momentum, reducing the likelihood of vehicle damage * Easy, convenient operation without leaving the comfort and safety of the driver's seat * Ultra durable and extremely strong; only the highest quality materials used in construction * Patented gear technology and 2-piece design ensures optimal locking strength * Forged gears provide superior strength and durability * Incredibly simple, yet effective, design employs minimal moving parts for maximum reliability * Thoroughly tested and proven * Most sold as kits with differential, activation switch, solenoid valve, air line, and bulkhead fittings * Front and rear Air Lockers available for most makes and models * For 4WD and 2WD applications * Easy maintenance; no special additives required * Also offered in ARB Traction Packs that include two Air Lockers, a compressor, and accessories for tire inflation

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.

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.
