Thanks, we don't have those but not sure we need them if not having trouble. Do they just dampen the travel by the idler sprocket when in tough conditions?
I don't have them on mine, lose a chain once in a great while, but usually because of a rock.
I didn't know they changed the spirals either. I have the first generation 4408, so there are upgrades since. I do know they changed the tensioner and how the front sprocket bolt mounts.
