Underdrive Pulleys for NA v6?

[Vattic]

Hey everyone, was just wondering: Bought my GP not that long ago and i'm almost positive that it's had barely a day of regular maintenence performed on it, save for changing the oil and the car just turned 127k.

So as I am getting ready to liven the motor up to possibly eventually be modded, I was planning on replacing the belts regardless but I was wondering - - is there a set of underdrive pulleys available for the Series III 3.8? I looked for a while but wasn't able to find any.

Any help appreciated.

probably something available, but don't expect any power increase from them, maybe 2 hp and then if you don't change all of them you can lose power at idle (alternator spins slower) from everything I've seen and read pulleys are the biggest waste of money as far as performance mods

ZZP offers the alternator and water pump ud pulleys. If you do both, you'll probably see around 5whp, maybe more in the upper rpms.
