05 Xterra OFF ROAD clutch kit

Does anyone know where I can find a clutch kit for the 05 OR Xterra, outside of the dealer?
I wore it down in 42K miles; all my other manual transmision cars I drove over 100K before replacing the clutch. I've been told its because of the X's heavy fly wheel. It also took some time for me to adjust my driving style to the truck. I'd like to find a more heavy duty clutch but nothing seems to be out there but the dealer item.

Nothing that I know of. Waiting for a centerforce myself.

me too!! i called them early this month and they said they should have one for the 06 X at the first part of next year!!!
