Excellent upgrade

Excellent product.

Hayden M6 Tensioner

Installation went good. Too soon to tell

Great product

By   on  Verified Purchaser

I run Hayden M6 Tensioners in all my Harleys. Smoother and quieter shifting. Easy to install. Lots of bang for the buck. Great price.

No more primary chain clatter!

By   on  Verified Purchaser

Great product to replace the weak stock part that Harley makes!

Hayden M6

By   on  Verified Purchaser

I replaced the stock Harley automatic chain tensioner with the Hayden unit on my 2012 Dyna Switchback. The stock unit only has one direction; tighter and tighter. The Hayden mounts on springs so it keeps constant tension on the primary chain. Install was easy and straight forward. I did have to file the metal portion of the unit a little because the nylon shoe was a little tight in spots on its mounting bracket. After filing, the shoe rides up and down smoothly in the mounting bracket. I also felt the price was a bit high for what you get too. But it is a big improvement over the faulty Harley stock unit. And I felt the Harley Screamin' Eagle unit wasn't a much better design. And its reviews said it was loud. The Hayden unit is quiet.

This thing is awesome

By   on  Verified Purchaser

Easy to install and noticeable in shifting (much smoother) and getting neutral.

Hayden M6

Easy installation. Seems to be working as advertised.
