Spec stage II clutch. Pressure plate is made by Luk....just about ALL pressure plates for this application are made by Luk. Stock trucks right off the production line have Luk discs and p-plates. Luk's are great clutches....for a stock application.
I tell you the major issue....it's a piss poor slave cyl design from ford. The line isn't at fault...there ain't much to go wrong with it period. Stupid part designed and manufactured by the frenchies.
'01 XLT disguised as a '03 Fx4 Level II.
