Internal/external balancing

It is NOT bolt on and go unless it has the recessed face. And you don’t have to space the damper, you have to space the water pump pulley and everything else that runs off the pulleys.

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.
