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

Red Front Knuckle Arms — Precision Alloy

This red aluminum front knuckle arm set is an aftermarket component for the Tamiya TL-01, GF-01 and WR-02CB platforms. The alloy construction stiffens the steering pivot compared with plastic originals, enhancing alignment control under load and supporting more predictable handling when refining setup.

Fitment uses the chassis' stock mounting points; verify compatibility with your hub carriers, wheel hexes and steering link geometry before final tightening. Ensure ball studs seat correctly and check for binding through full suspension travel. After installation, confirm toe-in and kingpin angles since the different stiffness can alter steering behaviour.

As part of a tuning program, replacing plastic knuckles with aluminum reduces unwanted movement at the spindle, which tends to sharpen turn-in and make steering feedback more consistent during iterative setup adjustments.
