The TKR5100 Aluminum Ackerman Plate (Gun Metal) is a CNC-machined steering geometry component used on Tekno RC 1/8 scale platforms, including the EB48, NB48, ET48, NT48, SCT410, and related variants. It is part of the front steering bellcrank assembly and controls the Ackerman angle, which directly affects how the inside and outside front wheels turn during cornering. By swapping or upgrading this plate, you can fine-tune steering response, improving turn-in sharpness, mid-corner balance, and overall handling feel depending on track conditions and driving style. It is a direct replacement for the stock part and is commonly used in racing setups to achieve more precise and consistent steering performance without changing the entire steering system.
