Why use a genuine Sanden AC compressor?

Many OEM AC compressors are a “variable displacement” design and don’t work well with older OEM or aftermarket AC systems

The OEM compressors have a 4-groove pulley instead of the 6-groove needed when moving the compressor to a higher location

Sanden is the aftermarket standard for AC compressors, recommended by most major AC manufacturers
