A direct replacement part of the lower suspension arm for your Team Associated RC18 truck, buggy or monster truck. You can use it either in the front or rear as both parts are identical. It should also fit some of the 1/18 rc clones on the market.
If the pins and screws are a very tight fit use a sharp carbide 2mm bit to drill out excess material. Be careful not to melt the PLA (or ABS) when drilling so better use the drill on lowest rev setting.
