now i might be wrong, but it seems that the clutch kit for the rubicon changes the springs out on the weights for stronger harder ones, which makes the bike shift up at a higher rpm in automatic. at least thats what i was told. and people have told me to get it for my bike but i am a little sceptic about instaling it myself they say you need a special puller for the casing you can see the instalation guide at highlifter.
