yeah thats the one. they make one identical to it without counterweights. but id like to get the one with counterweights to get into tuning the clutch to a t. ram says that set up is good to a thousand horse. i am well below that. would you run the exta springs?? i will have to get some weights and adjusters. if you have them how much do you want for them? BTW i am putting THE CAM in this winter also.
