Maxed out 80E is devised from most every high performance 80E part out there.. from sprag to 300M shafts and completely new valve body and a ton of clutches.. a bigger drum to hold them... just lots of goodies tossed inside really. I didnt build it... i simply told him the environment it would see and what it had to do... he says simple enough.. "how deep is your wallet son?" lol
