I just installed my ATI 25%/10% underdrive and the factory pulley weighed 12.4lbs and the ATI was 7.6lbs. That's almost 5lbs off the crank which is a big difference. Only thing is the a/c pulley is only a 10% underdrive, and I have a belt for a 25% underdrive which is too small, and the factory belt is too big. Anyone know the length of the a/c belt for a 10% underdrive? Factory is 41", and 25% is 38".

Thanks.

I warmed mine slightly, I'm talking less than 200 degrees and I was then able to slide it on just far enough to use the tool I have to pull it on the crank.
