Spur gear

Removes a relatively cheap and easy-to-fix point of failure which helps protect the rest of your drivetrain.

Can’t really think of any pros. If one is roasting through plastic spur gears in a crawler or trail truck to the point of needing a metal replacement then there are likely problems somewhere else in the drivetrain or with gear mesh.
 
I'm actually ditching the steel spur gear in my wroncho for a stock plastic spur and a slipper Eliminator. Like Topher said, I want a cheap point of failure. Right now I really don't have one

It’s pretty noisy but not too bad.

I had no issues performance wise with it.

I switched back to traxxas spur and it quieted down.
