I have been looking for an underdrive pulley set to put in my 1997 Sonoma Ext Cab with 4.3L, but I can't seem to find any. Any suggestions on where I can find some?

Is the alt pulley smaller? Im looking for a smaller on to lower my output at idle. Might as well get the whole set.

Get the race pulley set then. Slows down everything.

Why do you want more than 14.2-14.5 volts? That is more than
enough. More could fry your computer.

That wont increase the voltage. It will increase the amperage. My electric fans take alot of power, especially when the a/c is on.

Like $80-90 for the two piece steel set (black powder coated) or $185 for the three piece aluminum set. Both include a smaller alt pulley to make up for the lost power. The three piece set includes a third pulley (same size as the stock one, but it is aluminum). It looks nice to have the billet, and it might weight a little less a free a fraction more hp.

I have the two piece set and love it. No alt problems at all.

If you want to save the power for your compressors or your radio don't put on the new alternator pulley, leave it stock and just put the other one on.

Buy the March Power & amp 3 pc pulley set. Keeps alt power at
factory levels, But undrives everything else. I run them and
they work great :thumbup:
