This black anodized aluminium coupler turntable is provided as an aftermarket replacement for the coupler assembly on Tamiya Tractor Trucks 56505. It is intended to improve coupling consistency and offer a more rigid pivot surface for scale tractor-trailer connections.
The component reduces unwanted movement at the coupler interface while still allowing the necessary rotation as the trailer articulates, supporting improved alignment and predictable towing response.
Fitting is done by removing the original turntable, transferring any suitable mounting hardware and linkages, and securing the new unit in the same location. Verify rotation and alignment during final assembly to ensure correct operation.
A practical aluminium upgrade for maintaining consistent coupling geometry and simpler alignment checks on Tamiya Tractor Trucks 56505 setups.
