Does anyone know where I can buy an aftermarket high output alternator (200+ amps) that will fit my 2005 F350?

 

There are several variations on how to get high amperage alternators. Many companies have versions that fit the Ford motors, here are a few from a quick google search.

Be careful on which high-output alternator you purchase & install. Many dealers will sell you a high-output alternator that's not matched to the v-belt on your engine & or it may be an alternator that requires 2 or more belt pulley.

I found out the expensive way on my Mercruiser 496 MAG HO engine. I finally ended up purchasing a Balmar alternator & separate regulator & it's stressing my v-belt to the limit (new belt approx every 30 hours)

 

What alt does the 05 have..The 3g or 6g...And do you have a 130 amp now?
I went from a 3g 130 to a 200 and I built it myself....Let me know.
