Over drive ALT. pulley ?
 

Does anyone know if there is a company that makes an overdrive Altenator pulley, Since I put underdrives on the truck its not charging as well as I want it to. And I would like to add another battery later on, and if this alt. isnt charging one I dont think it will charge two.

there area few company's that make overdrive pulleys. I'm not sure what they are though. You may want to try to just put the stock pulley back on a see if it works. Also, if you getting another battery for some reason (all i can think of is a huge stereo) in which case you may want to think about upgrading to a sn95 135amp alternator. It means you can still use the underdrive pulley and maintain full charging capacity.

I have the stock alt. pulley on it. I didnt get an underdrive pulley for it when I did it. All I changed was the crank and Waterpump. I was also thinking about getting a bigger 130- 135 amp alt. but hadnt decided. Wasnt sure if it would help or not if I cant get a different pulley

If you have the luxery of shopping junk yards you can find a smaller pully for your alt, smaller will turn it faster.

This place will make any pulley you want and probaly have the one you want in stock anyway http://www.aspracing.com/
