I found someone that i believe can make me a metal spur gear instead of the crappy plastic ones but i got a question.I was gonna send him the clutchbell and the spur gear but do i need to make one gear out of softer material so it will strip instead of messing up my differential or should i have them both made out of the same material?Sorry if this is confusing its hard to type what i am wanting to ask.

I would think that both would have to be hardened steel. If you get one made and it works, let me know how much you want for them!

No not as long as the slipper is still in place

i suggest sticking with plastic, you will defianately do damage down the line with a steel spur gear, i only use plastic, they make steel for many of my trucks but i keep them plastic, its easier to replace a spur gear than diff gears
