Tamiya TT01 Series Rear Knuckle Aluminum Upgrade JR-TT102-LB by Jazrider  [JR-TT102-LB]

Heavy-duty rear knuckle for TT01 models

The JR-TT102-LB serves as a durable aluminum rear hub / knuckle arm for Tamiya TT01, TT01E and TT01ED chassis. Finished in light blue anodize, it replaces the OEM plastic knuckle to improve rigidity and resist wear where steering and suspension load the hub.

Fitment uses the factory mounting points and original fasteners so the geometry is retained and stock toe and alignment settings should carry over after installation. The metal part preserves baseline handling while offering increased stiffness for drivers wanting more consistent rear-end behaviour.

Tuning advice: because an aluminum hub reduces flex at the wheel connection, expect slightly sharper corner entry and more predictable rear feedback. Check bearing condition and tighten hardware as part of the installation routine.
