Yeah it's good or them but at the same time can push customers elsewhere, if you are running a supercharger you have to pay an extra $148 for the light cr crank pulley. They are awesome pulleys nonetheless.
Finally put them on yesterday with help from a friend. Took a little over 2hrs since we didnt have a lift. Changed the serpentine while I was at it since I found a Gates off of Ebay for 15. Not much of a difference at WOT, but in traffic I feel a huge difference which I LOVE. This DIY helped a lot! Thanks =)
