The ARB Air Locker® system is a pneumatic locking differential that is activated by a dash mounted switch.
A small charge of air, from an on board compressor, activates the locker which in turn locks both axles together providing 100% traction.
When not activated, the ARB® operates as an open differential and does not have any adverse effect on driving or handling.
• Driver controlled, push button action for 100% instant traction.
• Up to 100% stronger than the stock differential in most cases.
• The Air Locker does not have a high wear rate or require more maintenance than a standrad differential
• The ARB patented design has proved to be ultra reliable.
• The Air Locker does not have any adverse effect on tires, transmissions or handling in highway operation, unlike automatic and limited slip differentials.
• The most versatile locking differential.
• No belts, pulleys or cables required.
• Air compressor can also be used to inflate tires and accessories
