These aluminium front knuckle arms are an RC-scale replacement part made for TAMIYA TT-02B and DF-02 chassis, finished in light blue. They serve as a direct upgrade option where users want a metal alternative to standard plastic knuckles to change steering feel and durability without altering the chassis layout.
Installation is straightforward for hobbyists familiar with basic front-end work: remove the original front knuckles and fit the aluminium units using the existing mounting points and hardware from your TT-02B or DF-02. No special tools beyond standard hex drivers are required, and the parts are intended to interface with the stock steering linkage and wheel hub assemblies on those chassis.
From a tuning perspective these knuckles act as a durability and feedback modification rather than a geometry change. Swapping to aluminium can reduce flex under load which may yield a firmer steering response and more consistent behaviour across repeated runs. Use them as part of a measured setup process alongside tyre choice, toe settings and shock tuning to evaluate net handling changes.
