I am curious if there are any members who have this installed and have had issues?

Thank You

To some extent this is true.

IF your thinking about replacing your oem pulley for an aftermarket?

invest in a pulley from a reputable manufacturer cheaper is not always the best option.

Mine finally broke after 30k without any warning which resulted in a small portion of the hub to remain.

It was a PIA to try to remove on my own with the right tools.

I ultimately had to give up and take to a local shop for it to finally get removed.

IMO the slight 5-7hp gain are not worth it.

If you wrench on your own car, and don't mind the eventual time bomb?

Have at it who am I to keep you from avoiding a potential problem down the road.

Invest that $ somewhere else.

enjoy!
