TAMIYA Compatible Rear Hub/Knuckle Arm for TT01 Models - JR-TT102-BK by Jazrider  [JR-TT102-BK]

Rear Hub & Knuckle Arm Details for TT01 Models

The JR-TT102-BK is an aftermarket aluminum rear hub and knuckle arm designed specifically for TAMIYA TT01, TT01E and TT01ED chassis. It substitutes the stock plastic hub carriers with a stronger alloy component, delivering a firmer mounting point for rear driveshafts and steering linkages while keeping the original chassis geometry.

Compatibility is confined to the named TAMIYA TT01 variants, so ensure your chassis code matches before fitting. The part is machined from aluminum to improve resistance to wear and deformation compared with the factory plastic, and it preserves the original attachment pattern for direct replacement of wheel hexes and driveshafts.

Fitting involves removing the original plastic carriers, transferring bearings and set screws where applicable, and installing the aluminum carrier onto the rear hub assembly. Once fitted, check driveshaft engagement, wheel runout and steering linkage clearance through full suspension travel. The upgrade increases rear stiffness and can influence toe characteristics without altering the pickup locations.

For long term service, monitor mating surfaces and bearing condition and replace tired bearings rather than forcing them into the carrier. This item is intended for RC model use only and is not suitable for full-size vehicle use.
