The ARB RD208 Air Locker is a pneumatically actuated differential locking unit designed for the rear axle of the Suzuki Jimny, fitting the 26-spline, 10-bolt carrier configuration. ARB Air Lockers are the industry-standard in selectable locking differentials — trusted by professional off-road drivers, expedition overlanders, and 4x4 enthusiasts worldwide.

Unlike standard open differentials, an ARB Air Locker forces equal torque to both wheels on the axle when engaged, ensuring maximum traction in mud, rock, sand, and other low-traction terrain. It is driver-controlled via an in-cab switch connected to the vehicle's air supply (ARB compressor required separately), so it can be locked for the trail and unlocked for normal road driving.

Installation uses the existing axle housing with no permanent modifications, and the locker can be engaged or disengaged on the move at low speed. Paired with a Jimny A-pillar snorkel and ARB compressor, this is one of the most impactful off-road upgrades you can make.
