Advanced Technology and Design

An Air Locker ARB solves the problem of transmitting "traction" to a wheel that's in the air or slipping. It replaces the center of the original differential, and when engaged, positively locks the front or rear differential, providing equal traction to opposite wheels. By directing traction where it's needed, you benefit from dramatically improved traction, enabling you to tackle difficult terrain with control and confidence. Please note: LINX compatible

ARB designs and manufactures Air Lockers in-house, using state-of-the-art machinery and a large group of highly skilled and specialized engineers. Every part is meticulously built to exacting precision, and every locker is rigorously tested to ensure reliability in the harshest off-road environments.

Why choose Front Blocks?

A rear lock will significantly improve your 4x4's off-road capability, enabling you to tackle difficult terrain in a much more controlled manner. Adding a front lock will take your 4x4's capabilities to the next level, allowing you to exploit your vehicle to the full.

ARB Air Locker vs Electronic Lock

The ARB Air Locker Differential Lock offers many advantages over conventional electronic locks.

Electronic locks can only be engaged at speeds of up to 8-10 km/h. This means you have to slow down or even stop to engage them - and even then, activation takes time. Imagine you're halfway up a hill and you need to lock the differential. With an electronic lock, you have to stop, activate and wait, which compromises your ability to get going again because the momentum has been lost.

But with an ARB Air Locker Differential Lock, a simple flip of the switch provides instant locking at any time, and its super-strong design allows activation at any speed.
