Does anyone know where to get the LS1 chain dampener or know anyone that sells one? My chain has quite a bit of slack in it and it's still fairly new. Any help would be appriciated!

Edit. I found the stuipd thing, but why in the hell is it so much money? Does anyone make a cheap one?

 

From everything I have read, the slack is normal. Never seen one cheaper, not sure why it is so much money either as it is more than a chain
