Jazrider Tamiya TA01/TA02/DF01/FF01 Aluminum Rear Knuckle Arm JR-TA109-BK - RC Spare Part  [JR-TA109-BK]

Aluminum rear knuckle for Tamiya TA-series

This black anodized aluminum rear knuckle arm is made for RC use with Tamiya TA01, TA02, DF01 and FF01 chassis. It replaces the stock rear knuckle to give a firmer mounting point for the hub and axle interface and is intended for hobby-grade setup and maintenance.

Fitting is straightforward: remove the rear wheel and hub, check the condition of ball bearings and link pins, swap the original plastic knuckle for the aluminium unit and reuse compatible stock hardware. Make sure the part is oriented correctly, tighten the mounting screws to the recommended torque and then confirm toe and wheel alignment before running the model.

Used as a tuning upgrade, the metal rear knuckle decreases flex compared with many OEM plastic pieces, helping to keep rear geometry more consistent under load and through suspension travel. Pair it with correct rear hubs, good bearings and properly adjusted suspension settings to see predictable handling improvements.
