Philippe FrenchVerified owneron Treal Hobby Promoto Hardened Steel Transmission Gear Set (30T/40T/50T)

Solid parts. I went with knockoff gears a couple months ago, and I was constantly cleaning fine metal shavings out of the transfer case and off the motor \ shaft. Not good. Treal parts have always been rock solid for me (though I did break the brake caliper servo arm off of the Treal 7075 caliper. Bad head-on collision with concrete) and this isn't a bad deal. The fitment was excellent and I wish I'd gotten these first instead of the cheap Amazon ones (Brk RC I believe) These are hardened steel and they handle my Castle Mamba system just fine.
