SFI Balancer

[subcom]

My Propeoducts/PRW or whatever brand it is aftermarket harmonic balancer has lost all harmony. Are there any higher end SFI balancers out there for a factory, externally balanced 5.9 crank? Anybody used this one?

Looks like a decent damper, I'm currently using a SCAT externally balanced 360 LA damper for my build. 65

Reviews for this Pro Products one are pretty bad.

Here’s another one I might consider. All others are for internally balanced cranks or LA motors.

I had a pro comp/speedmaster, and while it looks great it detached from the inner hub. I could spin it by hand. Summit's reviews have another guy with the exact same experience.

On a related note what's available for a balancer for a 360 magnum these days? All I have is the one that incorporates the serpentine pulley. I need one without that so I can bolt on an LA engine v belt stack

The SCAT brand I'm using has both sets of imbalance. LA/Magnum, you can bolt on the one you need. 65

For my purposes I definitely don't need anything crazy like an SFI rating

I ended up buying the Blueprint non SFI one. It looks exactly like the Proproducts one it replaced. It comes with the 5.9 Magnum weight installed by default.
