Aluminum PS Pulley
Aluminum PS Pulley Does anyone have the Aluminum PS pump pulley? If so, are there any drawbacks from it? Mine just cracked and I am looking to get an aluminum one. Thanks
Got a link? Only alum PS pulleys ive seen are aftermarket. No problems should come from the stock plastic piece unless you bonk it, then its toast. LSx trucks used a steel pulley of the same dimensions which Im running currently
I bought mine from http://store.wazees.com/Category/11-...s-engines.aspx
Have not installed it yet, want to get it anodized.

being that the stock pulley's plastic, i doubt an aluminum one would be any weight difference enough to give or take any horsepower. if it was lighter, i can't see it giving you anymore power than what the dyno would fluctuate from run to run.

I have a 2010 L99/LS3 P/S pulley. You can get to all three mounting bolts and I'm pretty sure it's steel (seams awfully heavy if it's plastic).

I just can't see paying $60 for a plastic pulley from GM and then having it break again. SO I think the aluminum one I saw on Ebay might be the ticket. Plus I can get to the bolts.....
The L99 pulley is not plastic, it's only $25, and you can get to all the bolts. What's not to like?
