Traxxas Gearbox Halves w/Idler Shaft

For less then a third of anything else out there this is a good case, yes its stock but it doesn't get exposed to most of the rigors that other parts go through. Though with no heat sink for the motor and a gaping hole in the bottom, there is plenty of room for improvement. Also with the plastic motor mount natural tightening of the motor causes impressions on the mount and future adjustments can "slide" into the older mounting point, I've never really had a problem with that or the heat with my big motor and constant spur size changes.

Best basher case made. Tough and no metal heat sink to get bent out of shape (been there and done that).

They're the manufacturer replacements, what you would expect.
