ARB Product Range

ARB Air Lockers®

Created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance, ARB Air Lockers employ a 12 volt air compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. 

Differential Covers

ARB Differential Covers are perfect for both competition and off-roading, where harsh off-road work is to be encountered. When off-road, it is inevitable that you’ll encounter obstacles that could potentially inflict expensive damage to your differential.

ARB Differential Breather Kit

The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water. This is achieved with a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.

Adjuster Nut Pliers

For correct pre-loading of an adjuster nut type differential, these adjuster nut pliers have been designed specifically to easily and safely accommodate the full ARB Air Locker® range of adjuster nuts and most original equipment types.

Shim Driver

For installing and servicing common shim pre-loaded differentials, the shim driver is designed to evenly distribute the installation force around the outside edge of a differential shim as it is tapped into place, allowing thinner shims to be inserted into tighter places than would otherwise be possible.

Differential Spreader

To achieve the required carrier bearing pre-load during setup, the differential spreader has been designed to be quickly and easily used with most shim-adjusted automotive differentials. It allows the housing to be stretched in a safe and controlled way, reducing the risk of damage.

Bearing Puller Kit

The bearing puller kit offers a unique way of removing a differential carrier bearing, which allows easy removal of the original bearings with less chance of damage.
