Every AutoTech Engineering unit is assembled 100% in Riverside, California. With over 100 years of combined, “on hands” experience and the fact that we have been in business for over 28 years has allowed us to source and supply the highest quality component parts to ensure your unit exceeds expectations. All are plug and play unless over wise stated. Some modifications such as adding spacers or plug harness are included at no extra cost. Voltage is set to OEM minimum specifications on each unit ordered unless otherwise requested. If you need higher voltage, contact us before ordering online. **Technical note: you may need to raise up idle rpm with an external tuner as high output alternators require minimum of 650rpm. Most Chrysler vehicles idle at 600rpm
