Just by adding a few electrical accessories such as driving lights, auxiliary cooling fans, or a mega-sound system you can quickly exceed the capacity of your Jeep alternator. POWERMASTER has the solution - high output alternators that bolt in place of the OEM alternator. They feature a slightly larger case that bolts to all factory brackets and use the same belt. POWERMASTER has reengineered the power curve to deliver up to 50% more output at idle. Every POWERMASTER high output alternator is tested and comes with a proof of performance tag.
Works great and as intended
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.
Beautiful alternator. Works great. Had to re-clock it, and broke it in the process (my fault.) Customer service was great, sent it to them and they fixed it and clocked it for me for very little more than the cost of shipping.
Does this fit the AMC/Jeep 4.2L 258 L6 with V-Belt? Thx

Would existing harness/wiring plug right into the Powermaster or does it require modification or alteration of any kind?? It's going on a 2001 jeep cherokee sport 4.0 4x4.
