Overview
Replace the stock plastic 5th wheel coupler on your MFC-equipped Tamiya 1/14 tractor truck with the Hot Racing CNC Aluminum MFC 5th Wheel Coupler. CNC-machined from solid aluminum and finished in a clean black anodized coating, this direct-replacement coupler is designed for use with the Tamiya Multi-Function Control Unit (MFC) — delivering the rigidity, durability, and precise engagement that scale tractor truck owners demand.
The 5th wheel coupler is one of the most-used and most-loaded components on a 1/14 tractor truck — it's the connection point for every trailer you couple to, and every twist, jounce, and tug runs through it. The aluminum construction eliminates the cracking and flex that plagues plastic stock couplers, ensuring secure trailer engagement run after run.
