^ Yah, that's exactly what it is.  It's for the Nitro MT.  It works well in the elec MT, but requires some modification to get it to work.  The aluminum Sprint steering setup bolts right in with no modification.  The weak link in the MT's stock setup is that metal rod that connect the steering arms.  A turnbuckle/threaded rod with ballcups will get rid of most of the slop.  The all-aluminum setup in the picture gets rid of ALL of it.
