TAMIYA TT01 Rear Hub/Knuckle Arm Replacement - JR-TT102-BK by Jazrider  [JR-TT102-BK]

Detailed Rear Hub Replacement for TT01 Chassis

The JR-TT102-BK aluminum rear hub and knuckle arm is an aftermarket upgrade made for TAMIYA TT01, TT01E and TT01ED models. It swaps out the factory plastic hub carriers for a machined alloy unit to provide a firmer mounting for rear drive components and steering linkages, helping to limit flex during braking and cornering while retaining original geometry.

Fitment is specific to the listed TAMIYA TT01 variants, so verify your chassis code before purchase. The aluminum construction improves wear resistance compared with stock plastic and preserves the original mounting layout so wheel hexes and driveshafts align correctly.

To install, remove the original rear carriers, transfer any bearings or retaining hardware, and secure the aluminum unit to the rear hub assembly. After installation, inspect driveshaft engagement, wheel runout and steering linkage clearance through full suspension travel. Note that the part affects rear stiffness and feedback but does not change suspension pick-up points.

For maintenance, regularly check mating surfaces and bearing condition and replace worn bearings to avoid premature wear. This accessory is for RC model use only and is not intended for real vehicles.
