6 Traxxas Slash cars used for oval racing, all 6 have the ST Racing Concepts hinge pin kits in them, Why?? simple they dont get loose and come out and their fitment is just a bit looser than stock and provide a bit less friction, for faster acting spring and shock action.

These polished and heat treated king pins fit great and eliminate those tiny annoying e-clips as fitted with the stock king pins. I'm using these with RPM caster blocks which works fine. Unfortunately these are not as robust as I was hoping for. They are harder to bend than stock king pins but still will bend after a huge landing or clipping the wheel on an obstacle.
