dirty dawg clutches explanation please.

Ok, on his site for the ranger 900 clutches, there is not much explanation of what each kit will do for me. The first kit is $651 and it has the springs with it and some weights and helix and back part of my clutch. So what will this kit help and change about my bike. Will it give me EBS and better shifting or is this something that if i want the EBS i have to buy the primary clutch for that is $429. or just buy the Ultimate clutch package $1000. Just want to know so if i can achieve what i want out of the simplest kit or do i have to go for the ultimate package he sells. Thanks for any help and I am running 31 inch outlaws.
