When the cab of your Case, International, or Case IH tractor turns into an oven mid-season, the solution isn't a new machine — it's the right conversion kit. Our fitment-specific A/C Conversion Kits replace aging York and piston-style compressors with modern Sanden-style rotary units that deliver better cooling efficiency, lower engine load, and full R134a compatibility. From classic International 66 and 86 Series row-crop tractors to Case IH Magnum workhorses, each kit is sourced from AP Air and includes everything needed for a complete installation — compressor, receiver drier, expansion valve, hoses, and O-rings — so you can restore factory-quality A/C at a fraction of the cost of new iron.
