ARB - Volkswagen Amarok Rear Air Locker (2023-2025)

ARB Air Locker Differential

The ARB Air Locker is engineered to deliver maximum traction and control in the most demanding off-road conditions. Designed and manufactured in Australia, Air Lockers are trusted in over 100 countries worldwide for their strength, reliability and proven performance on challenging terrain including rock, mud, clay, snow, sand and gravel.

When engaged, the Air Locker locks both wheels on an axle together, ensuring equal drive is delivered to each wheel regardless of available traction. This provides forward momentum where standard or limited slip differentials allow power to escape through the wheel with the least grip. Off-road this difference is substantial, making the Air Locker one of the most effective traction upgrades available.

The latest generation features a precision-machined two-piece case and forged internal gears, delivering outstanding durability and resistance to fatigue under high loads. The patented internal gear timing system improves strength and responsiveness, while reducing the number of moving components for greater longevity and reliability.

Backed by an industry-leading five-year, unlimited mileage warranty and supported by ARB’s global dealer network, the Air Locker provides peace of mind whether touring, working or competing.
