they are the same as the Emaxx for pins and holds 12 as well, I got a couple of them

Awesome! are the team associated pegs any better than the traxxas pegs?

I use 12 stock mgt pegs unsure of diameter, I always crank it tight with no slip or it'll burn em up but with attention to gear mesh i get good life out of them

nice assortment of kimbrough and delrin monster gt spur gears on ebay

Yeah, i've seen them. I wonder if the white GPM delrin is up the task. i don't think the actual teeth is the weak spot, but the pegs seem to be the weak spot.

I doubt it, the slipper is the same exact thing as traxxas, with the exception of the spring and locknut
