Kilby AirBoss Onboard Air

Kilby AirBoss Air Compressor Systems

Available for 2007 + Jeep Wrangler JK - Kit Includes:
KE-2200 Compressor Mounting Kit, 25-513352 York Clutch, EF210R York compressor, FS-07-050 intake filter, 44760 rotolock fittings, 99-431 York dipstick, KE-ACCKIT-JK, accessory kit, KE-AT2.5 air tank

It's a well known fact that if you want an onboard air system, there's no better air pump than a York Compressor.  The problem is only a handful of vehicles came with the desired factory York air conditioner Freon pump that could be converted to pump air for onboard air systems.  On top of that the newer the vehicle, the harder it is to convert and mount an old York pump for this purpose.  Well fret not.  Kilby Enterprises has taken much hard work out of creating a York onboard air pump system worthy of serious bragging rights.  Their kits cover many popular 4x4 engine configurations and take into account existing AC units and under the hood clearances.  Kit typically contain an array of parts including, the York Compressor, Compressor Mounting Kit, Air Accessory Kit, Air Tank Install Kit, Oil Return Kit, Coalescing Filter, Air Tanks, Pressure Regulator, Check Valve, Pressure Switch, Intake Filter, Air Manifold, Safety Relief Valve, Universal Couplers & Rubber Covers, Gauges, Pulleys, Hose and Hose Fittings, Toggle Switch,  rotolock fittings, new belts, etc.
