The ARB CKMA12 High Output 12V Onboard Air Compressor provides a compact onboard air source for operating ARB Air Lockers, inflating tires, and supporting air accessories on Jeeps, trucks, rock crawlers, buggies, and other off-road vehicles. Built for permanent 12V installation, the CKMA12 combines a hard-anodized cylinder bore, Teflon-impregnated carbon fiber piston seal, thermally protected motor, and sealed construction for dependable operation in demanding environments. The CKMA12 works especially well when you need one compact compressor to handle both locker activation and general onboard air without taking up the space of a larger compressor system. Integrated manifold ports support ARB Air Locker solenoids, while the included pressure switch, wiring harness, relay, switch, mounting bracket, and safety components give builders the major pieces needed for a clean permanent installation.
