    Description

    More Power. Upgrade to the 120 Amp PA Performance Jeep Alternator. This YJ alternator is a brand new upgraded replacement, not re-manufactured like other companies sell and is tested at the time of assembly for complete reliability. It comes with internal voltage regulator and a 6 groove serpentine pulley. The 120 Amp alternator will increase the charging capacity at all RPM Ranges and produces 60+ amps at idle and 120+ amps at maximum .

    Peace of Mind. Why waste your time and money rebuilding your alternator over and over when it will only fail, replace it with a brand new high performance alternator that includes a Limited Lifetime Warranty directly from PA Performance for peace of mind.

    Application. The PA Performance Alternator is an upgraded replacement to be installed on 1987 to 1990 Jeep Wrangler YJ models equipped with a 2.5L or 4.2L engine. This alternator requires an upgraded output wire (4 gauge or larger) and at least 175A fuse protection for installation.
