This is a complete transmission assembly for your Wraith or Axial SMT10 based build.  This can either be used as a direct replacement in your SMT10, or this will fit aftermarket chassis if building a truck from scratch.  These come with an aluminum case and spur gear cover, along with full metal internal gears. 

Note:  These arrive with a 48p spur gear installed and pinion gear included.  These can simply be removed and your larger 32p spur/pinion gears used.
