Yes I have looked and found that most people buy the lightning tensioner but i haven't found out if the pulley itself is ribbed or not. I really only need the pulley as mine is making a little noise and want to get a new one but i have read you can't just buy the pulley. I read that the lightning part number 1L3Z-6B209-BA is the one i need but just want to make sure its actually infact the ribbed oem pulley as I dont want the flat one. Thanks guys!
