For Tamiya TA01/TA02/DF01/FF01 - Aluminum Rear Knuckle Arm JR-TA109-LB by Jazrider  [JR-TA109-LB]

Direct-fit aluminum knuckle for Tamiya chassis

This machined aluminum rear knuckle arm is intended as a direct replacement for Tamiya TA01, TA02, DF01 and FF01 rear hub assemblies that benefit from a stiffer component. The light blue anodize helps with quick part ID while the metal construction reduces the flex typical of stock plastic knuckles, preserving steering geometry when the car is loaded.

Fitting the arm is simple for anyone familiar with basic Tamiya service: take off the original knuckle, check the hub carrier and fastener condition, then secure the aluminum arm using the original screws. No specialist tools are needed beyond common hex drivers; tighten carefully to avoid putting excessive stress on surrounding plastic parts.

During setup this part provides a more positive rear steering feel and serves as a robust spare for regular track use. After installation, re-check alignment and bearing clearances to ensure the vehicle behaves as intended on road or dirt surfaces.
