Marvel: How do you like your UUC pullies?

[FRANCO]

I wanted to either get UUC or Evosports pullies. however, Dinan came out with an article saying that Evosport's efforts can ruin the harmonic balancer and in turn rui the engine. Is this true? Would you still recommend myself in getting pullies?

[MarvelPhx]

What Dinan is referring to is the harmonic balancer. It is a large weighted pulley attached to the actual crankshaft of the engine. Replacing the harmonic balancer can cause problems with our engines.

The EvoSport (nor RE as far as I know) pulleys do not replace the harmonic balancer. They replace the alternator, power steering, and water pump pulleys.

I have had no problems whatsoever.
