This ARB Air Locker can instantly lock differentials and allow you to tackle the toughest off-road terrain. This air locker can be installed on either the front or rear axle of a 1997-2002 Toyota FJ Cruiser with a 8' IFS 53mm bearing locking differential and 3.91 & up gear ratio with 30 spline. The ARB Air Locker is a pneumatic locking differential that uses air to facilitate the locking of both axles. This action converts your differential from a conventional open to a full spool type axle supplying 100% power to both wheels to keep you going through the worst terrain. Your vehicle's standard (or open) differential is designed to allow each wheel to turn independently, thus eliminating binding during turns. While off road this becomes a major burden as engine power will take the path of least resistance, which occurs at the wheels with little or no traction.
