Engineered as an aftermarket upgrade for the TAMIYA BBX BB-01 chassis, this front upper suspension arm set delivers improved rigidity and repeatable mounting compared with common plastic arms. The components are produced from 7075 aluminium to provide a stiffer, serviceable solution while retaining BBX BB-01 fitment and clearances.
The arms function at the front upper link locations and are intended for hobbyists focused on suspension setup and tuning where roll stiffness and steering input are tuned. Installation is a direct replacement process using the supplied hardware or the original chassis fasteners, taking care to apply correct torque and thread-lock on metal fixings.
Select these CNC-style 7075 arms when you need a tougher front mounting point and consistent behaviour under load; verify alignment and secure metal screws appropriately for long term performance.
