modify gears shreading my piston

I bought a set of modify torque gears that come pre assembled and there is no need for shimming. I instaled it in a v3 gearbox with a brand new modify polycarb piston. I am useing a m120 ish spring. It worked well for about 100 rds then the first 9 plastic piston tooth all shreaded right out. It shreaded the right side of all the teeths. Should I be useing a half tooth piston? I tought those we only for helical gears? Why has it failed so fast?
