The ARB air locker has been around over 15 years. They have been tested at about every hard-core wheeling spot on earth and have proven their performance and reliability. Many customers who are in snow and ice country prefer the ARB for the front end because of its ability to be unlocked. This helps when turning on snow and ice covered roads where regular lockers tend to plow forward not wanting to turn as easily. The fact is no matter what the terrain the ARB give you the option of going locked or unlocked and that's the best of both worlds.
