This clutch is made for serious horsepower. People have used them in 1,000 HP DSM with no problems. And being gear driven, no clutch clattering noise. This is the 6Bolt AWD version. It has never been used. Also included is a new throw out bearing, clutch fork, pivot ball, and bolt guard. People have used the bolt guard, which is from the 2G DSM automatic, to protect the aluminum flywheel from the flywheel bolt, as they can chew into the flywheel. You can use it or not.
