TOM HAYDEN ENT M6 Primary Chain Tensioner M6BT65

Now you can have the proper chain tension during acceleration and deceleration with the big benefit of improved shifting. Your transmission will click into gear instead of clunk. Automatically adjusts the primary chain on 65-16 Big Twin, Sportster models. Once installed, the tensioner automatically self-adjusts the tension on the primary chain to provide constant and even tension, improving transition in gear shifting, reducing shift noise making for a smoother ride, as well as extending the life of the primary chain.
