Air lockers and electric lockers are both designed to provide maximum drive to all wheels of a 4x4 vehicle. Air lockers are air-operated differential lockers that use compressed air to engage or disengage the locking mechanism, ensuring that all wheels turn at the same speed. Electric lockers, on the other hand, are electronic locking differentials that use an electromagnetic mechanism to capture 100% of the available torque and distribute it equally to all wheels. While air lockers have been traditionally used in off-road racing, electric lockers are becoming a popular choice for high-performance applications such as off-roading, trail riding, and rock crawling. Electric lockers offer smooth engagement and validated strength, while air lockers provide the strongest locking differential on the market with fast engagement and disengagement times.

Air lockers are faster and stronger, but e-lockers are easier to install
Air lockers and e-lockers are both designed to allow drivers to switch from an open to a locked differential, either through air pressure or an electronic switch. While air lockers are faster and stronger, e-lockers are easier to install.
Air lockers use pneumatic pressure via a source of onboard compressed air to lock the gears in place. This is generally activated via a switch on the dashboard, with the gears remaining locked together until the pressure is released. The top benefit of an air locker is that they are almost instantaneous (top ARB air lockers can engage in less than a second) because there is no need to convert signals to action. However, they require a source of air to operate, as well as solenoids and switches to go with the air line plumbing.
E-lockers, on the other hand, use an electromagnet to convert the differential into a spool. Inside an e-locker, the magnet pulls two roller cams apart, and ball bearings keep them separated. This separation pushes heavy pins down into the side gear of the differential, locking them together. These systems also work with the use of a switch that is mounted inside of the vehicle. E-lockers do not rely on an outside source of power other than 12-volt power. While this is an advantage over air lockers, e-lockers rely on roller cams for engagement, which means that even after the switch is flipped, a degree of rotation will need to occur before the locking mechanisms engage.
In terms of installation, e-lockers are generally easier to install than air lockers. Air lockers require a source of air, additional solenoids and switches, while e-lockers are simpler to wire, requiring only 12-volt power. However, both systems can be installed effectively by a skilled installer who knows how to route things and use quality materials.
Ultimately, the decision between air lockers and e-lockers depends on the specific needs and preferences of the user. If split-second engagement is more important than reliability, air lockers are the better choice. On the other hand, if ease of installation and not having to rely on an external power source are priorities, then e-lockers may be the preferred option.

Air lockers are more instantaneous, but e-lockers are more reliable
Air lockers and e-lockers are both designed to allow drivers to switch from an open to a locked differential as needed, either through air pressure or an electronic switch. While air lockers are more instantaneous, e-lockers are more reliable.
Air lockers use pneumatic pressure via a source of on-board compressed air to lock the gears in place. This is generally activated via a switch on the dashboard, with the gears remaining locked together until the pressure is released. The top benefit of an air locker is that they are almost instantaneous because there is no need to convert signals to action. However, they require a source of air to operate, as well as solenoids and switches to go with the air line plumbing.
On the other hand, e-lockers use an electromagnet to convert the differential into a spool. The magnet pulls two roller cams apart, and ball bearings keep them separated. The separation of these cams pushes heavy pins down into the side gear of the differential, locking them together. While e-lockers do not rely on an outside source of power other than 12-volt power, they rely on roller cams for engagement, which means that even after the switch is flipped, a degree of rotation will need to occur for the locking mechanisms to engage.
In terms of reliability, both air and e-lockers have their potential failure points. For air lockers, there is a risk of leaks, and the system requires more components such as solenoids, switches, and air lines. For e-lockers, there is a wire that can fail, and the motor can be damaged or affected by water and mud. However, e-lockers have the advantage of not having an air system that can leak, and they are generally considered simpler to install and wire.
Ultimately, the choice between air and e-lockers depends on the specific needs and preferences of the user. If split-second engagement is a priority, then air lockers are the better option. However, for most cases, e-lockers are a more reliable and practical choice.
