Yeah, that's why I'm trying to find an alternative. A&A recommended a Summit model (as listed above) but I had a less than pleasant experience with something I bought from them years ago, but if it's my only option over stock then thats what I will have to roll with.

Also as an FYI/warning , I had a miserable experience with Colorado Speed with the IW balancer I can't use. They want a 25% "restocking" fee for a part I didn't use and didn't even take the plastic wrapping off of. Must be nice to make $125 off of a return on a part they list as an in stock part. I'd have a little more understanding if it was a custom order part. Guess thats not how I do business, if I did I wouldn't have many of my customers left.

Just curious. Why would these pulleys not fit with the A&A kit ?

It's a clearance issue with the 6 rib system. The IW balancer is too deep.

They hit the bracket

Is that pulley same size as stock? Or bigger?

I can't find measurements anywhere so I don't know. Anybody know how much clearance is available (how deep can I go with a balancer)?

I have been through all of this and then some. I almost just switched to the 8 rib but at $1,100 I coudn't afford it with the motor build and all the other crap I did. I ended up just buying a new stock one for $180 because the summit one and the ATI do not fit on the Z06 with A&A kit. I am just going to do the 8 rib and flip drive later when I got some more scratch. I hate it because the motor was out, it would have been so easy.....

Can a bad crank pulley cause engine vibrations

A&A told me that the Summit would fit on my LS2. Hope thats the case.

I run this one with an A&A kit and 6 rib.

It isn't OD, just a better stock diameter option so the factory unit isn't a worry.

Quiky One

It will.

I'm surprised the summit site says it will fit a ZO6 as well. They use a different balancer due to the dry sump and the snout of the crank being different.

^^^ ya don't trust Summit's application guide..lol

The part number I linked is good for wet sump cranks only.

Speed Inc. sells that damper for less $

How about the Fluidampr for an LS3 car? I just bought a T-trim A&A kit and I'm glad I saw this thread. I was about to get an Innovators West. That would have sucked.

The Fluidampr is listed as 7.75"

The Professional Products is listed as 7.5", and it doens't say if it fits an LS3 car.

What about this 6% overdriven ATI?
