Reviews: Powermaster High-Output Alternator (Natural) - 43311

The stock alternator brackets on a Jeep 4.0 have to be ground substantially for this alternator to fit, as well as the nearby bosses on the timing cover otherwise will NOT fit. That's the only reason it lost a star with me, otherwise it's a powerhouse & charges an XS Power 14 volt gel mat battery sufficiently.

Installation in my 1997 Jeep Wrangler went well until I had to change out the pulley. Had to use air impactwrench. Other than that it's working fantastic and truck is idling smoother with improved gas mileage. Costs more than the stock replacement, but still less expensive than the competition. Would highly recommend!
