Upgrade for Tamiya Tractor Truck - Trailer Coupler Lock TTT-56505-04-S by Jazrider  [TTT-56505-04-S]

Heavy-duty coupler lock for scale tractor rigs

This replacement coupler lock from Jazrider, part number TTT-56505-04-S, is made for use with Tamiya Tractor Truck models as an RC-scale accessory. The silver aluminum machining is intended to stand up better than plastic or stamped couplers and to produce a firmer, longer lasting tractor-to-trailer connection on scale rigs.

The item is purpose built to secure the trailer coupling, reduce play at the hitch, and to assist with consistent tuning and setup changes. It does not claim compatibility with chassis outside the broader Tractor Truck family; always check fitment against your specific model.

Installation assumes the installer inspects the mount points and verifies the factory hole pattern before fitting. The coupler lock is designed to drop into the existing coupling area and operate within standard RC-scale coupling configurations without altering drivetrain or suspension parts.
