Before we get into which is better— air lockers or e-lockers —it's important to understand the purpose of (and differences between) each. For street use, locked differentials pose a problem.. Air lockers use a system driven by compressed air to lock the differential of a vehicle while E-lockers use an electrical system to lock the differential. Air lockers work very quickly and efficiently as do E-lockers, with only slight differences.
Electric Lockers vs Air Lockers Before we discuss the differences, let's understand what air lockers and electronic lockers are. An air locker locks the differential gears using compressed air supplied by an onboard compressor.. Discover the differences between manual diff locks, air lockers, and e-lockers. Learn why modern drivers prefer advanced locking systems for off-road performance.
