Sorry guys, I have been out of the country. I have both kits but only one of each left by this point. More on order. I do not stock any tensioners for the stock QD as that does you no good. Those belts are already way tight and the problem is that there is not enough contact on the top gear with the belt. Only a longer belt that will wrap around the gear is going to fix the inherent problem with the stock QD system.
