Katech Adjustable Tensioner Install and Torque Settings I have been asked many times about all the specs for installing a Katech Adjustable Tensioner, and I could never find the instructions. I found them, so here they are. I just want to make sure this is in the LS1Tech archive (for as long as this forum is around).
