My 4x4 flywheel is on its 3rd skim still fine .
I've gone through a few clutches now .
The one that's in it now is a brand new standard ford Delphi cover plate with ap 6-paddle .
And is fine .
My last one lasted bout a year, I launch it all the time and go drag racing 4 times a year. Was perfect until the paddle wore out.
Just got it re-lined and put it back. No problems .
