The JR-TT2B01-RD knuckle arm set replaces the stock front knuckles on TAMIYA TT-02B and DF-02 chassis with red anodized aluminum components made for 1/10 scale RC hobby models. The upgrade targets improved stiffness and repeatable steering geometry versus molded plastic, helping to deliver steadier steering feedback during tuning and regular track use.
Supplied as a pair, the parts are intended for direct use on the specified TAMIYA chassis and generally mount using the original attachment points and hardware; confirm fit with your wheel hex and kingpin configuration before final assembly. After fitting, recheck steering travel and toe to ensure correct alignment and safe steering function.
As an aluminum hop-up, these knuckles reduce front-end flex and can affect steering feel and durability under repeated use, serving hobby-level maintenance and incremental handling refinement rather than a complete suspension redesign.
