I'm with you on this one, lincpimp. To my knowledge there are no other options for the rustler/stampede differential. Strange, because everyone putting tons of power into either one HAS to be stripping planetary gears constantly and you would think some manufacturer somewhere would come up with a solution.
Especially where they are both very popular vehicles. It's not like they wouldn't sell any.
I'm waiting for the money to arrive so that I can move the setup from my signature into the truck. I don't know if I should run it 'cause I know it's gonna destroy the differential in just a few runs. Then the teardown begins...
