Just thought this should have been added. I know if I would have found this thread a month ago I would have got the chance to save my super charger. This is for those who have Rev 1 or Rev 2 of the Vortech Super Charger. I recommend installing this kit ASAP. I didn't as we didn't disconnect the jackshaft from the super charger the car was prevouisly installed on and drove for several thousands of mile swith no problem. Figure we could do the same we installed it without disconnecting it. unfornently it was splined correctly inside and within 75 short miles both the male and female ends of the jackshaft were destroyed. Striped of all their splines. And All i have to say is this should have been a sticky long ago.

Don't know to much about them. But it could save you time and money. Something I wish I had both of after not seeing these before hand. Again these are a must see for vortech systems.
