ARB Air Lockers can instantly lock differentials and allow you to tackle the toughest off-road terrain. The Air Lockers can be installed in both the front and rear axles. 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.
An ARB On-Board High Performance 12 Volt Air Compressor - Compact Size, CKSA12, High Volume, CKMA12 OR Twin, CKMTA12 is required for installation.
