This is an upgrade metal gear to replace the one plastic gear that is in the Tactic TSX45 servo that comes in Axial brand R/C vehicles. It is advertised as a metal gear servo but it only has three of the four gears being metal. This is a nice low cost upgrade that will help the stock servo last with out breaking. I am currently running this on a Wraith and SCX10 with metal steering links and the Axial metal servo horn. It has held up to all the abuse I could through at it, unlike the original plastic gear that broke the first time i was out crawling. Here is a video of the gear installed to show it works perfectly and another on how to install it. 

Bulk ordering is available to dealers, message me for more info.
