Penntex Voltage Regulators

  Below are regulators that will fit all of the Penntex charging systems. The one on the left is an aftermarket version that will fit and work exactly the same as the Penntex 3000 and 4000 regulators. On the right is a Penntex PX4000 factory new regulator. The PX 4000 will work in place of the PX 2000, PX 3000, and PX 5000 regulators. The PX 6000 regulator is for use on 2005 and newer GM vehicles only. The PX 7000 is for Ford vehicles 2009 and newer. The wiring harness will go from the alternator to the regulator.
