TAMIYA TT-02B Rear Arm Upgrade JR-TT2B05-LB Aluminum Light Blue by Jazrider  [JR-TT2B05-LB]

Aftermarket aluminium rear arms for TT-02B

The JR-TT2B05-LB aluminium rear suspension arms are an aftermarket replacement designed for the TAMIYA TT-02B chassis. Precision machining yields improved dimensional control over plastic components and supplies a solid mount for rear suspension links and hub assemblies.

This kit is suitable when you require firmer rear geometry for setup work or when replacing degraded plastic arms. The light blue anodised finish resists minor surface wear and helps with quick identification during maintenance. The arms are intended to use the TT-02B's original mounting points and hardware for a clean, no-modification swap.

In practice, aluminium arms limit flex under cornering loads, delivering more consistent toe and camber characteristics compared to stock parts; this improves tuning repeatability but can make the rear feedback sharper. After initial runs inspect fasteners and check clearances where the arm meets the hub carrier and shock tower.
