I was thinking about making these my next mod but I was talking to somone and they told me to not bother with them.. They said they could do more bad than good to the engine and also make it overheat and also leak oil form the crank shaft.. Is this somthing I worrie about or no?

I ran them before the s/c and never had any issues. They are quality parts.

One of my first mods, not overwhelming gains but they all add up ... Make sure though you're buying a Steeda with a built in balancer, and not a piggyback style like March.

Don't bother if you plan on getting a blower anytime soon. I don't look forward to installing my stock pullies again.

Do it...and while you're at it install a Timing adjuster.

Timing adjuster is a great choice too, but if you're going to get a chip / tune hold out for that and get the spark advanced that way.

Tyler is right...if you plan on getting a tune soon, don't do the T/A!

I had them on my 01. I felt a slight increase in power. I never had any charging or other power problems. I did develop an oil leak from the crank seal but dont know for sure if it was pulley related.

I had an oil leak from the crank pulley and had to go back to the shop to have the keyway re-sealed.

Did this and cat-back same day. Noticed an increase in power, but don't know which mod did it.
