Order the Old Air Products GM A5 to Pro5TEN compressor conversion kit for 1959 GM Models.

The Pro5TEN is an all aluminum compressor, which offers a smoother & quieter operation with less vibration & engine drag. Designed to bolt into the original A5 compressor bracket assembly & comes pre-filled with 220CC of Pag 46 Viscocity oil for easy installation.

The A/C system must be flushed & cleaned along with installation of a new or rebuilt drier & new condenser to validate the warranty as the steel condensers are full of rust and corrosion. The evaporator and expansion valve should be flushed or replaced as well. Failure to properly install the compressor will void any applicable warranty.



Sanden style compressors are the most popular and best suited for most street vehicles, even with larger interiors. Designed to bolt in using our compressor bracket assembly and comes pre-filled with oil for easy installation.
