TAMIYA TT01 Series Rear Knuckle Arm Upgrade for TT01/TT01E/TT01ED - JR-TT102-BK by Jazrider  [JR-TT102-BK]

TT01 Series Rear Knuckle Overview

The JR-TT102-BK is an aftermarket aluminum rear hub and knuckle arm intended for use on TAMIYA TT01, TT01E and TT01ED chassis. It replaces the original plastic carriers to give a firmer mounting point for rear drives and steering linkages, helping to limit deformation under loads while keeping original geometry intact.

This item fits only the named TAMIYA TT01 variants, so double-check your chassis code before ordering. The machined aluminum construction improves wear resistance where stock plastic can distort over time, and the attachment points match the factory layout so wheel hexes and driveshafts line up as before.

Fitting the part involves removing the stock rear hub carriers, moving over any bearings or set screws as required, and mounting the alloy carrier to the rear hub assembly. After fitting, verify driveshaft engagement and wheel runout, and confirm steering linkage clearance through suspension travel. The component changes stiffness and feedback but does not alter pick-up points.

For upkeep, inspect mating faces and bearing condition routinely, replacing worn bearings to avoid premature wear. This product is designed solely for RC model use and not for full-size vehicle application.
