Tamiya TT01/TT01E/TT01ED aluminum rear hub by JAZRIDER JR-TT102-LB  [JR-TT102-LB]

Aluminum rear hub for TT01 family

This JAZRIDER JR-TT102-LB is an aluminum rear hub / knuckle arm designed for use on Tamiya TT01, TT01E, and TT01ED chassis in RC scale only. The part replaces the standard plastic knuckle with a light blue anodized aluminum unit intended to increase rigidity and wear resistance where the rear steering and suspension link into the hub.

The component is intended to mount to the chassis using the original mounting points and fasteners; it is engineered to retain the same geometry as the stock item so alignment and toe settings remain unchanged when swapped. This preserves handling baseline while offering a metal alternative for hobbyists who want a firmer rear end response.

Practical tuning notes: using an aluminum rear hub tends to reduce flex at the wheel end, which can sharpen mid-corner steering response and make rear suspension feedback more consistent under load. Check existing ball bearings and mounting screws for wear during installation and use thread-lock where appropriate on steel fasteners.
