MMR has one for $210.

I have heard differing opinions on the Steeda.

Thoughts?

I am going with the SeanHyland pullies. I have heard that their pullies are stronger than the Steedas. I heard that the Steeda pullies can crack.

I originaly braught up the conversation about the Steeda pulleys because I read the info on Sean Hyland Motorsports web site. I don't know what long term affects the Steeda kit will have as far as durability. If there is a problem I couldn't imagine Steeda putting them on their own vehicles for sale considering Warranty issues. Having said that what Sean Hyland says about Harmonics makes since as well. Since both Sean Hyland and Steeda are priced close I would go with Sean Hyland pulleys. I did not read the info until after purchasing my Steeda's. Hope this helps. I have not seen the MMR's to comment.

Hey All,

If anybody know the Ford 4.6L and 5.4L OHC engines it's Sean Hyland. I'd trust Sean H. with my engine before the Steeda folks on this not that Steeda is bad just that Sean KNOWS the modular engine like nobodies business.

Just my two cents.
