The black anodised JAZRIDER aluminium rear suspension arms are a straightforward upgrade for the Tamiya TA07 and TB04 chassis. Replacing the factory plastic arms with aluminium reduces flex and helps the car hold its line under load.
Aluminium components give a firmer linkage that translates to more predictable handling, especially when exiting corners or under braking. The material also resists fatigue better than standard plastic arms.
Swap the arms using standard hex tools and inspect all fasteners once fitted. After a few runs recheck alignment and pin tightness to ensure the new arms are seated correctly and working as intended.
