Calling all Tamiya truck builders! This is a cool upgrade or replacement part for your 1:14 scale big rig. It's a black aluminum coupler and turntable hitch – that's the part that connects your tractor cab to the trailer and lets it pivot when turning. It's much stronger and looks sharper than stock plastic parts. This one set (part number TRU333-BK) fits several popular Tamiya kits like the Scania R620, MAN TGX, Grand Hauler, and Actros 1851 GigaSpace. It comes with all the necessary stainless steel screws (flat head, different sizes) you'll need for installation. If you're into RC trucks, you know having a solid, realistic-looking hitch is key for that authentic feel and reliable performance when towing. A great little detail part to make your model stand out. Just make sure your specific Tamiya kit is on the compatibility list before ordering.
