Can any one tell me what the rating is for a heavy duty Alternater on a 2015 F350 6.7 Lariet.

The book I have says Dual- 357 amp total for 2015. Or at least that's the standard config for the 6.7.

 

Thanks but after the rating for single heavy duty.

2015 - single 200-amp or dual combined 357-amp option with 6.7L diesel.

The 357A comes from them mounting the 157A standard alternator from the 6.2Ls as a dual with the same 200A unit on top.

 

For 2017, there are several new options:

Standard alternator = 157A

Extra heavy duty gas models = 200A
Extra heavy duty diesel models = 220A

Extra Extra heavy duty (gas models only) = 240A

Dual alternators diesel models only = 332A
Dual extra heavy duty alternators diesel models only = 377A

Note that certain option packs automatically bump you to a higher alternator output. My gas truck I ordered, for example, has the snow plow pack, upfitter switches, and 110V outlets. Therefore, I was automatically bumped to the 240A extra extra model.

 

From what I can se under hood I must have single 200A ? It is marked.

Sorry, Frank...didn't see you were referencing a 2015. If you have the snowplow prep, it will be a 200a.
