If i buy the ATI Damper without the A/C does the damper still sit in the same position for belt alignment? Or will it sit further back due to the A/C pulley not being there? Is it worth getting the one without the A/C pulley or shall i just get the non A/C as planned?

Also, where is the part number on the stock balancer? I have an LS3 with what i think is F-Body accessories but want to be certain before spending the money.

If you are running F-Body accessories then you will need the F-Body balancer. We have them for sale on our site with free shipping right now if you need the underdrive unit:

Belt alignment stays the same (again, as long as you have the F-Body accessories). Part # is 917243.

Free shipping to the UK?

Plus I don't really need an underdrive one as its twin turbo and going to be running over 800+. Would rather the full damping ability.

The one without the A/C will be cheaper, and of course lighter. It will still have the dampening capability as the unit with the a/c pulley.

The only benefit is if you want to have air conditioning.

as for PN, ATI has a huge table on their site for what you'll need.

Thanks, but I've seen that

I​​​​​ mean the part number for my current GM balancer, where on the actual balancer is it?

You might as well get the one with the AC pulley gives you or the next owner of the car the option to put ac on it and those things are tough to get off. It is not going to cost you any HP having the extra pulley as long as it is not hooked up.

Cool, i've got no problem with doing that, just wondered if there is any benefit to the non AC one.

Why would there be?
