Hello!

I will be replacing my belt tensioner here soon as its rattling. I found several options on ecstuning which brand have you all used? The price difference is not all that much. Also, what else should I swap since I'm already there?

 

Check to make sure you actually need a tensioner. The most common problem is the bushings on the tensioner shock fail and rattle. We offer our WMW delrin bushings to replace the stock rubber ones and solve the problem. Much cheaper option than a new tensioner.

But if you do end up needing a tensioner we have them too
