Is that the altenator your talking about? They say it is for the old body style, but wouldn't it work on the new trucks?

 

Hey guys what crank pully do i want?

-25% Harmonic Balancer, 800 charge ASP549900

-25% Harmonic Balancer 32% "Overdrive" Alternator, 700 RPM ASP549984

 

The crank pullies are all the same at 25% under. Charging differences are in how small the alternator pulley is.

I hope that makes sense.

 

Hit Man X, what about the altenator? Will that one work on my truck or do you know?

I called them and they said that one for my truck was ~280 for 180 amps and 300 for 200amps.

 

I looked at that pic and I think that is for the 350 Vortec motors. Our alternators use a one wire to battery and one or two on the voltage regulator. I guess those were the ones I was looking at are for the older trucks! lol

Either way, those guys sell quality stuff so you can't go wrong. It does cost a bit more than I was expecting too.
