Aluminum Rear Knuckle Upgrade for Tamiya TA01/TA02/DF01/FF01 JR-TA109-BK by Jazrider  [JR-TA109-BK]

Purpose-built rear knuckle for Tamiya TA chassis

This black-finished aluminum rear knuckle arm fits Tamiya TA01, TA02, DF01 and FF01 platforms and replaces the factory rear knuckle to give a more rigid hub mounting point. It is designed for hobbyists focused on setup and suspension tuning rather than cosmetic change alone.

Installation generally involves removing the wheel and hub assembly, checking bearings and link pins, swapping the original knuckle for this aluminium part and reusing compatible stock hardware. Make sure the knuckle sits correctly, torque fasteners to spec and then adjust toe or camber settings as needed before a test run.

As a tuning aid, a metal knuckle reduces plastic flex and helps rear alignment remain stable under load and through travel, which can refine handling predictability. Combine it with matched hubs, quality bearings and tuned suspension geometry to maximise performance benefits.
