I have some subs that draw a lot of current and I have a lot of lights on my jeep and planning to add a winch soon. Mostly just want the alternator to not struggle to keep up with everythingThe OE 117 amp alternator is plenty, why are you thinking of swapping it out? I put some occasionally very heavy amp draws (extended winching sessions) on my battery and have never had a problem.
Keep in mind that you'll never be running all of those together at the same time. Many Jeepers commonly run all of that on the OE 117 amp alternator without any issues whatsoever.I have some subs that draw a lot of current and I have a lot of lights on my jeep and planning to add a winch soon.

My 98 TJ has a 90 amp, and I see many 90 amps listed as the replacement output on RockAuto. Most XJs came with a 117amp which has the same case size, so if you want to upgrade that would be a bolt in swap.Keep in mind that you'll never be running all of those together at the same time.

The '98 TJ came with either an 90 amp or 117 amp alternator, depending on how well it was equipped. The 90 amp version was usually only found with the most basic stripped down models like without A/C. The majority of TJs delivered were fairly well equipped and most packages included the 117 amp alternator.

Interesting, my 98 is a Sahara but has a 90 amp. It probably isn't original.The '98 TJ came with either an 90 amp or 117 amp alternator, depending on how well it was equipped.

Glad I read your post. I will be replacing the battery in my 06 TJ soon after loaded winching was almost too much for it. Charge gauge going down and the Check Gauges light coming on. I wondered about a higher amps alternator but I feel the same as you, if 117 amps can't do the job, something is wrong.The OE 117 amp alternator is plenty, why are you thinking of swapping it out?

Yep I have even winched twice on my AGM battery alone when the engine couldn't be started yet the battery still had enough power left to start the engine once the engine problem was fixed. Granted neither pull was extended or heavy but both definitely had to winch the Jeep perhaps 20' to get off the trail.Glad I read your post.

Quadratec and Extreme Terrain have a 120A alternator for $180.Has anyone found a 117 amp replacement alternators for a 97/98'? My 98 Sahara has a 117 amp that is squealing and needs to be replaced, but all I can find are 90 amp alternators.
Yep, even my 97 SE, with no accessories other than AC, came with the 117.The '98 TJ came with either an 90 amp or 117 amp alternator, depending on how well it was equipped.

Any had any experience with OMIX or PA Performance ? Rev for OMIX wasn’t great. PA seems okay, but haven’t heard of them beforeQuadratec and Extreme Terrain have a 120A alternator for $180.
Most of the other websites list only a 75 and 90A.
