Mean Green Alternators...DB Truck Customs (a Ramforum Vendor) can hook you up with one. I am pretty sure these things charge at 220amps@2,000RPM.

1998-92 RAM(FS) 5.2L(318),3.9L(239)

they are nice but so expensive
i would be fine with like 160 amps

SmokedRam · Nov 23, 2012

Hmmmm...dont know where you'd find that bud. Advance's Worldwide Alternators for your truck are 136 Amps...

Off road rams came with a 136 amp alternator, factory literature suggests a 160 amp was standard but I cannot find one listed.

Are you absolutely sure of that? The 2000 Offroad Rams list the alternators as being 136 amps.

Looks like the 360 1st gen Durangos came with a 160 amp alternator and will bolt right up to a 360 in the Ram...I would assume it will also bolt up to a 318 too...

Yeah, I corrected my post...old factory literature suggests 160 amps but it was never offered as a production item probably due to costs. The idea being an enthusiast would want to add more auxillary lighting.
Some of the adds I work with are produced before an actual production run. You should read some of the old muscle car adds from the late 60s and early 70's!

BTW, I had been looking for that old road test to verify some info before you posted. Now its saved to my favorites. Thanks!

thanks for all the replies i found one on ebay 200 amps for a 1998 dodge ram 2500 with a 5.9 diesel on the picture it looks just like mine anybody knows if it would fit ?

SmokedRam · Nov 24, 2012

Te pullys are different I think...according to Advance the Cummins alternator has a 74mm pully and uses a V belt...yours has a 57mm pulley with a serpentine belt...other than that, they appear identical. clocking is the same and all.

zspace 92 · Nov 25, 2012

then if i use my pully im fine ?
is so thats great i will buy it

SmokedRam · Nov 25, 2012

I cant say yes or no to be totally honest...all I can tell with info on the OEM alternators on Advance's site, the only difference is the pulley diameter.

zspace 92 · Nov 25, 2012

well thanks for your help i buy and sell alot on ebay so i will buy try it out it and if it doesnt work i will sell it

zspace 92 · Dec 5, 2012

just for info a 5.9 diesel alt will fit on a 318 the pulley doesn't and the body of the alt is just a little bigger

SmokedRam · Dec 5, 2012

Did you swap out pulleys or was that a no go too?

zspace 92 · Dec 5, 2012

yes i did and it works and best of all it is cheap 175 cad $ for 200 amp

SmokedRam · Dec 5, 2012

Awesome!

Theres a local company to me called tenney alternators, they build a nice ho alt for not much more than a oem. They normally build custom for spl stereo guys but I have talked to them and they are selling to diesel guys too, cause with lighting, stereo, and all the addons oem just isnt keeping up. You can find them facebook and they will ship anywhere. And powdercoat any color for additional cost

on tapatalk from my GS3....

zspace 92 · Dec 6, 2012

thanks i already bought the diesel one

Okiespaniel · Dec 6, 2012

I wonder if the diesel alternator would work on a 2000?

zspace 92 · Dec 7, 2012

cant see why not look on your alt if the numbers end with 7912 then it is the same as mine then it will fit what i saw at the junkyard the dodge ram Cherokee and Dakota alt all mount the same 3.9 5.2 5.9 gas are all the same so if the wiring fits and it looks like yours it should fit
