I'm sellling my 3400 stall that I used for about 4 months. I refurbished it in January, took it off on Monday and since I had warranty on it I took it to refurbished again so it can be brand new for whoever wants to buy it. It's a TCI 3400 stall with a 2.5 STR. It's the older version of TCI's, the better ones. It works awesome, those who have driven my truck can tell you how it feels. My best time with it was a 13.1 in 90degree weather. $400 shipped. The reason I took it off is because I'm getting a bigger one.
