An SFI certified dampner is required if you run 10's. I have a BHJ.

You don't need an aftermarket dampner unless you build a stroker or do something to change the internal balance on the crank...

Even with the same balance, an aftermarket dampener is most likely better over stock. Car manufacturers develop almost every component in the car, whereas aftermarket specialist companies focus on specific components, and so have much more R&D into it. The better you can dampen harmonic resonance in the crankshaft, the better the likelyhood that it will survive longer under more extreme conditions. I hear Fluidampr are best for street motors that stay under 7000rpm. Above 7000, ATI appears to be better. Stock is probably fine, but if you want to over-engineer, get an aftermarket one.

The stock damper is junk. It does not perform under heavy torque like when you install a KB. Look what happened to my stock damper few months after installing my KB...

I replaced it with a SFI approved harmonic balancer from Jegs. Good quality! Just my .02

get a romac. they are the best balancer so far for the 4.6. a good balancer is like good insurance. kinda like a billet oil pump gear. if they are that cheap off of ebay then something is more than likely wrong with it. they usually sell for 230 or 330. not 100%sure which one.
