Thanks for this info.

 

just fyi.....i went to do the gc 136a upgrade myself.....it didnt work out, the 01 cherokee has a different connector on the back.

had to go back and get the stock one (117a for me apparently)

 

To get the 136 with the plug for the 01 try a rem van from 01 they changed the plugs on everything the same year.

 

writeup?

here you go!

If you have a 1999 or 2000 xj and are looking to upgrade from the 117 amp alternator to the 136 amp, here is the list of vehicles that came stock with the 136 and have the same mounting and connector.

2001 dodge dakota 2.5l

'99-2000 multiple dodge trucks/vans

'99-2000 dodge ram pickup 5.2l

Hope this helps some of you.

 

First one will not work (pulley too big, mounting points not exactly the same)
Third one will also not work (pulley too big, too many grooves)
Second one will work, and agrees with the list in the guide i posted

 

Thanks for the clarification Dukie. On the mounting points, I got nothing. Pulleys however, are easily swapped. So here's a followup question; Since belt tension is adjustable does a 2-4 mm difference in pulley diameter make a noticeable difference in output?

 

I've posted a list of donors up to 160A (OEM applications.)

If you get one with a seven-groove pully, you can use it - just put the belt toward the rear of the pully, leaving the front groove open.

Upsizing across the 120A level does typically require grinding away about 1/4" of the mounting area, but that's doable fairly easily.

A wiring upgrade is indicated - the larger-gage wire allows you to take full advantage of the larger alternator, and you'll need to upsize the fuse anyhow (which is why I offer ANL kits - for that very reason. Trying to find fusible link wire larger than 12AWG is a pain, and the OEM is 10AWG. I haven't been able to find even that in bulk in the last several years...)

 

i just did the 98 grand swap into my xj 120 amp way beeter!! just had to shave the bracketr down a bit and it bolted right up

 

Chrysler did offer 130 amp alternators.

 

which engines have these alts?

 

Did it plug right in?

 

Mine came off a 5.9L

#56027913 is the correct one

 

Sweet. Thanks, I'll be doing that tomorrow.

 

Did the 120 AMP upgrade on my 98 little bit of grinding on the bracket and a tad on the block

Also due to the Bigger pulley on the new alt
I went uP a size in belts to 96 7/8. ( one inch bigger than stalk

The 120 Also has a extra notch so just tuck the belt closest to engine
