Internal/external balancing

I know that was the case at one time, but it looks like they fixed that? Or at least that's what their reply on that page suggests (I trust their reply more than the picture summit uses).
But I haven't bought that exact sku, so can't say for certain, but the information provided says that's the balancer OP wants. If it's not right, should be easy to send back to summit and let them know Fluidampr is FOS.


The only FD’s that don’t require a 3/4 inch offset is those with a recessed face. Without that recessed face the FD a is .750 thicker than an OE damper and that’s the issue.
