Are Losi thread on pinions hardened?

[lincpimp]

I am wondering if the stock thread on pinion gears that come with a LST2 clutchbell are hardened? I know that they are used with plastic spurs.

I only ask as the tin coated pinion gears seem much heavier than the stock ones.

Just checked with a magnet, and the stock losi gears are al... That sucks. I guess I will have to buy a few hardened ones from Mike.

Any other info is welcome!
