Great tension!

The moment I put this spring idler I could notice a considerable difference in the chain tightness. I actually thought it was too tight at first, Just had to adjust the spring spacing then all was good. Great product overall just wish it had 4 mounting screws like the original tensioner.


I enjoy all your products. Your a great product with a lot of choices. I will be back for more.
