Does anyone know of a company that makes an alternator upgrade kit for my 99xj? The only extra amps I'm pulling from my jeep so far is an 8k lbs smitty built winch and it's not happy when I put a heavy load on it. I am going to be adding light bars and other accessories hopefully in the near future and for see a problem here with the stock alternator.

Second, has anyone or does any know if they make a locking style over head center console for the xjs? I've looked all over the web and found tons for the wranglers and cjs but nothing for xjs.

 

Popular upgrade is to do a Durango 136 Amp alternator swap. Full write up here: https://www.cherokeeforum.com/f67/19...ctures-179443/

 

Yup, that was my 136a upgrade.

You should absolutely upgrade your wires along with the alternator. John Kelley from Kelley's works in progress sells heavy duty wiring kits that are perfect. I haven't heard or seen from him on the forums for awhile though..

His website is kelleyswip.com and his username is "5-90" on several forums.

I bought the 4awg wire kit which has a 150a fuse on it. If you desire more than a 136a alternator you can do 1awg wire which has a 200a fuse and use a 160a Durango alternator. That would be the exact same process as the 136a, just more expensive. Also, most people will say that 4awg is plenty for 160a but I think the problem comes from not being able to find a fuse that is larger than 150 but smaller than 200.

So in short, a 136a alternator from a 1999 Durango with a 5.2 motor will work with minor modifications, and you should absolutely upgrade your wiring also.

 

I concur. I bought his kit not to long ago. it was about $150 shipping included if i remember correctly. He is in the middle of some family things, so he may be slow responding right now. Very impressed the the quality of his product. Took about an hour of install time. I did the complete main kit with a ANL fuse.

 

I used a Durango starter on mine and had it custom rewound for a total of 160 amps (157 really lol), I also use Kellys wiring setup on mine.

 

Awesome guys thank you very much!

 

Here's a 240amp alternator

Have you run one of those. I was looking at them earlier and going to post a thread asking about them.

 

And you might want to think about adding a 2nd battery also.

 

No I have not run it myself. I only know about it because it was on someones build sheet awhile back. He said he had 4,000 miles since install and no issues though.
Don't know much more than that about it. Sorry.

 

Did you do 4awg or 1?
