what is the best choice for underdrive pulleys. Going on a 1992 firebird

 

I got the Hypertech's, very nice, worked well. However I don't use the alternator pulley. I put it on and my alternator bit the dust a short time later, not due to the pulley and I didn't put it on the new one. I don't have any charging problems, of course I don't run a huge stereo or any other power sucking accessories except my Passport 8500 radar detector.

 

how much do they cost and where did you order them from. What pulleys did it come with. do you think it made much of a difference? Thanks

 

I bought them through Summit. Don't remember the exact price. Well I just checked Summit and Hypertech website. Apparently they quit selling them. So I would go with March, they are high quality and yes they really help.

 

I'm using the March pulleys from Summit..$78.88
