the tensioner should take the slack. I used the stock belt. With the smaller alt pully I got a lot of belt slip. To difficult to get the belt just right without slip and was having charging problems--due to the slipage, truck wouldn't start leaving me asking for a jump in the parking lot. After all was said and done, i went back to stock pullies and belt.
