A buddy helped me install my AMS Lightweight Pulleys last night. We only got the crankshaft pulley installed because we couldn't get the bolts loose on the alternator or water pump pulleys. I think I'm going to have to take it to a shop with an impact wrench to break them loose and put the other two on for me.

Anyone else running lightweight pulleys?

I've got some pics I'll try to get up tonight.

 

You will need to remove the raditor fans to get the impact gun down in there. Otherwise there wont be enough room. Over and above they are more hassle than they are worth. Indeed they do look good, but they produce no significant gain in hp vs the stock pullies. Not to mention if you run aftermarket amps/subs your altenator will be spinning twice as fast and will last half as long. Some disagree to that, but smaller pullies burn altenators like a candle.

 

They aren't smaller pulleys...all three are the same size as the stock ones, just lighter.

 

in that case after removal of the radiator fans it will be a walk in the park. Impact gun will take them right off there. They make any bolt a breeze, not to mention fun to use

 

ive got the ams pulley set.. ehhhh...didnt feel any difference.

 

you wont need a impact you just need to put something through one of the holes in the stock pullies to wedge it so it wont move and get a breaker bar or cheater bar.
