Default Which underdrive pully?

Thinking of getting an underdrive pully this weekend, but not sure which one.

ASP or SLP?

They are about the same price & the SLP comes with the crank bolt. I'm thinking the SLP because it has the higher rim to keep the belt on?

Any advice?

The ATI super damper is probably the best as far as dampening goes, but it is only available up to a 10% underdrive. The March fluid filled damper isn't very far behind in dampening ability and when you consider that the fluid is not rotational weight, is also pretty light. The SLP/Powerbond has tall walls to help prevent thrown belts. The ASP is probably the lightest out of the bunch, but is not known for it dampening ability. It's your decision, but I tend to lean towards the March damper as the best all around underdrive damper IMO.

I have had an asp on my car for over 1/2 it's life, never had a problem because if it. Just get one that is SFI approved, so you don't have to worry about it.
