3 year warranty, but if you read the small print it is voided if it is installed incorrectly(which it was). The only thing I have going for me is the fact that Vortech recomended the installer to me and they failed from the start. I have miles of documentation that was sent to the original installer as well as vortech. I should be in the clear here I hope, I'll find out within a couple days. On the bright side it speeds up my install of the LSD and Clutch now. Since the mechanic is working on my car he said he'll do everything we have been planning to do.
