Tamiya TL-01/GF-01/WR-02CB Front Knuckle Arms Upgrade TL01-13304-RD by Jazrider  [TL01-13304-RD]

Performance Front Knuckle Arms in Red

These red aluminum front knuckle arms are an aftermarket upgrade built for the Tamiya TL-01, GF-01 and WR-02CB family. The stiffer alloy reduces steering spindle flex relative to plastic units, giving more predictable inputs and a firmer steering feel that helps during aggressive setup work.

Install using the original mounting points and confirm that the knuckle clears your hub carriers and wheel hexes before final torquing. Verify ball stud engagement and ensure there is no suspension bind across full travel. After fitting, re-evaluate toe and kingpin geometry since the new stiffness can affect turn-in and mid-corner balance.

For tuning, alloy knuckles make steering inputs more repeatable, which simplifies fine-tuning of shock rates, roll stiffness and steering throw during track testing or tyre changes.
