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

Stiff aluminum knuckle for rear steering stability

This aluminum rear knuckle arm replaces the stock plastic piece on Tamiya TA01, TA02, DF01 and FF01 chassis where a machined metal component is preferred for strength. The light blue anodized coating makes the component easy to spot and the alloy construction reduces deflection compared with standard plastic knuckles, which helps keep steering actuation consistent under heavy loads.

Installation is typical of Tamiya parts: remove the factory knuckle, inspect the hub carrier and screw threads, then install the new aluminum arm with the existing fasteners. No special equipment beyond standard hex drivers is required; confirm proper thread engagement and moderate torque to avoid stressing adjacent plastic parts.

From a tuning viewpoint the aluminum arm tightens rear steering feedback and improves repeatability for frequent track sessions. It also functions as a durable spare for club runs—always recheck alignment and bearing clearance after fitting to ensure predictable handling.
