Specs At A Glance

Good To Know

Q: How do I know if my regulator has failed? A: Common signs include a battery that will not hold a charge, dimming or erratic gauge behavior, and voltage that climbs too high or stays too low while running. A quick charging-system voltage check will confirm whether the regulator is at fault.

Q: Does this replace the factory regulator directly? A: Yes, it cross-references OEM number 6S8-81960-00-00 and uses the factory-style connector. Confirm your model and year match the listing before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
