I just put in a south bend dd 12 button ceramic-ceramic #3600 pressure plate, Just tried it out and it is way way less grabby than my 600 horse single disc was, I also noticed that the clutch dont grab untill my pedal is pretty much all the way out, it also seems like my truck just dont seem like it has as much power as before when I give it some throttle and also it is hard to shift when just sitting still with the clutch in and I dont hear what so ever that dd clutch rattle either or any drive train shutter like I think it would . Is the clutch not disengaging all the way? Maybe I need to up grade my hydraulics? The installation went great and followed the instructions with great detail, is there something that needs adjustment or something?

 

The new ones are sprung hubs and have noise dampers so they dont rattle, def get the upgraded hydrolics
