Help with LSx Harmonic Balancer Swap Hi there, I am changing over the harmonic balancer (damper) on my LSx454 from the stock OE type to a Power Bond.
The OE balancer does not have a key, but the power bond does. The crankshaft end does have a keyway. I bought what I thought was the key I needed but it is way too big.
Is there a specific key I have to ask for, and is it a genuine GM part? Here are some pictures
Thanks in advance.

You can just leave it out unless you're going to run a blower pulley. The balancer is tight enough that it can't move and you won't need timing marks, if the pulley even has them.
You can run it without but if the balancer has a keyway and crank is cut for one,I would find one that fits and use it.Measure it and go a hardware store and look threw there woodruff keyway assortment or machine shop.

Thanks all, your help is very much appreciated. Looks to me like this is the one I need, but as mentioned I don't strictly have to run it. But since its off and apart I may as well fir it.
I would also look at a ATI balancer. With that big stroke you are going to need a good one. Also you don't want a underdrive it takes away the ability to dampen with the smaller dia.
