What Owners Say
Owners and enthusiasts consistently praise ARB Air Lockers as virtually indestructible, with many reporting they've never experienced a single problem even under demanding off-road conditions. The lockers themselves are considered extremely robust—tough enough that you'll likely break other components before damaging the ARB unit. Installation does require significant time and effort, particularly for the onboard air setup and front differential work, and some users note that most problems trace back to installation errors rather than product defects. While air lockers add complexity compared to e-lockers (requiring a functioning compressor and leak-free lines), their proven durability and reliable performance have earned them a strong reputation among serious off-roaders who demand dependable traction control.
