I'm going to be purchasing a new clutch kit in the next few days. I'm curious on what's so much different between these two kits on rockauto other than brand and price. The LUK on rockauto doesn't specify if it is a complete unit with flywheel whereas the perfection clutch does specify. Its for my 2010 Pat 4wd t355. Im kicking myself for not just changing the clutch when I rebuilt the transmission earlier this year. Its not slipping or anything. I am getting clutch chatter and its a smidge noisy. Do you all know if the LUK comes with the flywheel? I did change the bearing when I did the transmission, but if I'm getting an entire kit. I'll just put another new one in.
