yeah, i know. i've done lots of pulley's before. Most do require a puller, but ours aren't that hard to take off. I was surprised also.

 

so when can we buy?

 

there is a Group Purchase currently going on, on jbody.org. He just yesterday and he has almost 30 orders. He only has the altenator pullies going now, the cranks will come later. The deatails are on www.jbody.org in the group purchase forum.

 

Or howzabout an estimated cost so we can start filling our piggy banks.

 

The coated Altenator Pullies are $60, the raw are $50

 

I ask the following question out of ignorance, what's the advantage of the coated ones???

 

dont know looks i suppose...............nothing performance wise maybe duarabilty think i have what md-hhr non coated i suppose?

That's a direct link, there is a difference in color, and i'm sure durability. That post has all the information you need though.

 

Thanks guys for keeping people up to date.
A4 hard coated parts last longer due to, added wear resistance, chemical resistance, and help strengthen the part, by filling in some of the pits / mirco-cracks in the aluminum surface.

 

I'm coming to this forum looking for MPG-improvers. I'm a 15 veteran of modding and drag racing Camaros and Trans Ams...not a newbie to engine modification by any means.

What I can't get past is how you guys expect to maintain the longevity of your motors with the Harmonic Balancer replaced with this lightened aluminum unit. For the LT1 motors we would never have considered lightening the balancer/pulley, but under-drive crank pulleys were common.

Without the balancer you're looking at pretty massive damage to the bearings after a while.

What am I missing here?
