This set replaces the stock rear knuckle arms on TAMIYA TT-02B and DF-02 chassis with light blue anodized aluminum pieces. The components are intended for the rear suspension and hub mounting points used on compatible 1/10-scale touring and drift setups.
The aluminum construction offers a firmer mounting surface compared with molded parts, helping to maintain hinge pin alignment and rear geometry under load. Improved repeatability in those points can make rear toe and steering behavior more consistent as you tune other suspension elements.
Installation follows the chassis' existing rear hub locations; remove the factory knuckle assemblies, fit the aluminum arms in place, confirm hinge pin alignment and tighten the fasteners. After assembly, verify wheel alignment and clearances before running the model.
These parts can be used as a direct replacement or integrated into a staged tuning plan where rear stiffness and predictable geometry are a priority. They are intended for RC-scale chassis upgrades only.
