TAMIYA TT-02B Aluminum Rear Knuckle Arms (Red) by JAZRIDER JR-TT2B03-RD  [JR-TT2B03-RD]

These aluminum rear knuckle arms are a direct-fit RC-scale replacement designed for TAMIYA TT-02B and DF-02 chassis configurations. Machined from metal, the parts provide a stiffer mounting point for the rear suspension compared with common molded alternatives, and they are finished in red to match upgraded hop-up styling.

Installation is straightforward for model builders familiar with TT-02B/DF-02 maintenance: remove the stock rear knuckle arms, reuse the chassis hardware where applicable, and refit the alloy arms using the original mounting points. Verify hinge-pin alignment and wheel geometry after installation to maintain predictable handling.

In practical tuning, aluminum rear knuckles act as a low-flex upgrade that helps preserve suspension geometry under heavier loads or more aggressive driving. Use them when you need a solid metal replacement for routine repairs or when dialing in rear-end feel for practice and local track use.
