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

Toyota locking axles are a great choice for axle swaps; 8 in. E-locker differentials are strong and versatile. Wiring a Toyota E-locker differential to work outside of its donor vehicle is possible but not as simple as just splicing a few wires. DIY instructions for this modification have been published for decades. For years, Low Range Off-Road had been selling sections of factory Toyota harnesses to be converted into universal harnesses. That process involved cutting and splicing the ends onto six-lead trailer wire. Not only is trailer wire expensive, it isn't even the correct wire gauge. When added up, the cost of a DIY harness can easily surpass $150. Put simply, making your own harness by splicing into an OEM harness is a pain in the neck! But several years ago, Low Range Off-Road embarked upon the goal of creating the best purpose-made wiring harness kit for Toyota E-Locker axle swaps. They wanted an easy-to-install harness that requires as little modification to the vehicle as possible. After a few revisions, they offer what is now the Ultimate E-Locker wiring harness kit. These harnesses are made up of OEM-grade cross-linked insulated wire. They use wire gauges that match the factory harness. Each harness is 18 ft. long and available for both low pinion and high pinion differentials. Please verify the plug shape on your differential to make sure you get the correct harness plug. Some newer low pinion differentials may have high pinion plugs. Harnesses come with either "Front Locker" or "Rear Locker" labels. * Compatible Toyota electric lockers are found in the rear of 1996-2015 Tacomas, 2007-14 FJ Cruisers, and 1996-2002 4Runners. High pinion front axles can be found on 1993-97 FJ80 Land Cruisers * Harness is supplied with (2) 15 amp fuses: (1) ATO and (1) mini fuse * Low Range Ultimate Harnesses cannot be used on 2016+ Toyota Tacomas * These harnesses are designed for dual-plug lockers that have 6 pins on the large plug and 2 on the small plug. There is a rare variant, mostly found on 2011+ Tacomas, that uses a single 8-pin plug. Single plug lockers are not compatible with the Ultimate E-locker harness.
