Tamiya Tractor Trucks Coupler Lock - TTT-56505-04-BK by Jazrider  [TTT-56505-04-BK]

Compact black coupler lock for Tamiya 56505 applications

This coupler lock is an RC-scale replacement part intended for Tamiya Tractor Trucks 56505 use. The compact black aluminum design helps limit unwanted play at the trailer coupling interface for more reliable retention during towing and practice runs.

Installation uses the original mounting point: remove the factory coupler fastener, place the lock into position, and secure with the factory hardware. Routine hex drivers and basic hand tools commonly used on Tamiya chassis are sufficient for fitting.

In tuning contexts the lock provides mechanical retention to stabilise the trailer tongue and maintain coupling alignment, which assists in reducing lateral movement and achieving steadier hookup behavior under load.
