Pair of Tamiya Juggernaut/ TXT1 aluminum differentials from RC4WD never used

This is a pair of heavy duty and light weight aluminum differentials from RC4WD that replace the pot metal case/gear in a TXT1 or Juggernaut differential. Uses stock 3 gears inside which are assembled with all new parts from a Juggernaut kit. Sat for years but have never been ran in a truck. Much lighter and stronger than the stock pot metal case/gear that come with the kit.
Thanks
