What you end up with on the stock units is a 1mm contact point that gets really hot and the gears can micro weld to themselves to the crank. So as the car is ran really high and hard you get these micro welds once the car is turned off and everything cools down. Then when you go to push the clutch in to start the car it shatters... This is how it happens everytime. The tensile strength of the oem Sintered gears is about 6,000 psi and the new billet Chromoly steel is over 140,000 and it's a harder material which will be stronger and more resistant to micro welding.
