My daily driver 69, 340 4spd dart, occasional strip car has 12,500 miles on my tensioner. I put one on it to help fix my slopped double roller chain. Even has the chain that's not smooth and supposedly wrong for a tensioner. Have had it apart 3x changing my solid cam to hydro street cam every time I go race it. Looks like the motor has never rotated it looks so mint. Don't ask me??? But that's my experience
