The ARB CKMTA12 is ARB's high-output twin motor onboard 12V air compressor, engineered for 4x4 vehicles requiring fast tyre inflation and reliable air locker operation. With two independent motors, the CKMTA12 delivers significantly higher airflow and faster recovery times than single-motor alternatives — ideal for Jimny builds running both front and rear ARB Air Lockers plus tyre inflation.

Like the CKMA12, the twin motor unit mounts permanently under the bonnet and operates on 12V DC. Its larger dual-cylinder design means less heat buildup during extended use, such as airing up all four tyres simultaneously through the ARB manifold kit. ARB has engineered the CKMTA12 to handle the most demanding off-road air requirements over the vehicle's lifetime.

For serious off-road Jimny builds running dual lockers, rock crawling, and regular trail use, the CKMTA12 is the definitive air supply solution.
