As per title, i have used advance search but fail to find it.

Subject was Rear crank shaft oil seals up rated and maybe even a group buy possibly two years old?

Two reasons a standard rear seal would fail either too much positive crankcase pressure due to a poor breather system/worn piston rings or too much crankcase vacuum from an overkill race setup like those running a 5 stage dry sump setup on a sealed system.
So can't see why you would need to upgrade it?
