Q-tec or StreetPro?
I had the dual 3" QTP's have had issues with both of them each one has been rebuilt at a cost to me and they were less than a year old.
Both of them has come loose to the point of almost falling off..luckily my car goes on a lift at least once every two weeks just to poke around. And I am talking about the motor parts not where it attaches to the cutouts. oh well...they are off now. going with DMH's. Faster and a 4 year warranty.
