This rear knuckle arm set is an aluminium upgrade tailored to TAMIYA TT-02B and DF-02 suspension layouts. The light blue anodized finish identifies these replacement parts for the rear hub and mounting points on compatible 1/10-scale touring and drift cars.
As an aluminium component, each arm provides a stiffer mounting surface than typical plastic knuckles, which helps retain hinge pin alignment and rear geometry during dynamic loads. That stability supports finer tuning of rear toe and steering feedback when adjusting other suspension items.
Installation uses the chassis' existing rear hub points; remove the OEM knuckles, position the aluminium arms, ensure hinge pins align and torque the hardware. After fitting, verify wheel alignment and clearances before running the car.
Use this set either as a direct replacement or as part of a staged tuning approach where improved rear stiffness and consistency are priorities. These parts are intended for model chassis use only.
