OBS Air Management Systems

Belt-driven and engine-driven onboard air compressor kits for 1988-2000 Chevy/GMC C/K series trucks. Whether you're running train horns, air lockers, air tools, or a full onboard air suspension system, these York-based compressor kits mount directly to your engine's accessory drive for reliable, always-on air supply without a bulky electric compressor draining your battery. Choose from Pre-Vortec, Vortec, LS swap, and Duramax diesel specific kits, or build your own with our universal D.I.Y. kit. All kits ship with a brand new (not remanufactured) York 210 compressor, mounting hardware, and full installation instructions. Replacement parts and accessories - filters, moisture traps, pressure switches, air tanks, and more - are also available to service or expand your system.
