I can't help but feel that those are a bad idea. The crank pully isn't just a pulley - it's a harmonic dampener. It has a big heavy mass on a rubber vibration damper that helps absorb crank vibrations. Very important on RB's. That pulley there has no damper whatsoever, and is aluminium, so it has no mass either. That's kinda the exact opposite of what you want a crank pulley to be.

Yea what he said, don't buy that crap. If you want something better than stock, get an ATI or Fluidamper.

Yea, I would run a damaged stock balancer then those aluminum bits. Echoing those above, get something better:

I would even hook you up to save you from going down that route. Hit me up.

how much does the rubber affect its performance? My pulley has the rubber partially torn.

They have no rubber dampening.....I would be terrified to run one of these!!
