AC compressor rebuild

I agree in that the Sanden compressors are more efficient. But they are like 8.5 cubic inch displacement while the Mopar V type is over a 10 cubic inch displacement. Kind of like comparing a smallblock to a bigblock. If your car is not a high RPM car with low gears, the original V type compressor is fine. If your car is a street car who cares how much the V type compressor weighs. Ma Mopar did make a high pressure cutoff switch for use on the cop cars somewhere along the line. It would disengage the clutch, like when the cop would kickdown his car as in pursuit with the higher RPM.
Then again most rebuilds that are available today are crap. I'm pretty sure Classic Auto Air does a good job of rebuilding them
