The Tamiya 54254 Aluminum Rear Upright is a precision upgrade made from blue-anodized aluminium for a stiffer, longer lasting rear end. Intended for TRF201, DB01 and TRF511 chassis, this upright swaps the stock 1050 bearings for larger 1350 units to cut friction and decrease servicing intervals.
Perfect for track-focused builds and precision tuning where smoother rear rotation and reduced wear matter to lap consistency.
