This aluminum rear knuckle arm set is an RC-scale replacement part designed for Tamiya TT-02B and DF-02 chassis. Finished in gun metal, the alloy units replace the stock plastic knuckles to provide a firmer mounting point for the rear suspension and wheel hub assemblies while keeping the standard geometry intact.
Fitment and installation follow the stock layout, removing the original plastic parts and fitting these aluminum arms using the existing hardware and hinge pins. Minor trimming or setup changes are not required for standard TT-02B and DF-02 builds, but check clearances for aftermarket wheel offsets or thicker tires before final assembly.
In tuning terms, aluminum knuckles reduce flex around the rear hub pivot, which can give crisper steering response and more consistent rear toe under load. They are primarily a durability and precision upgrade for hobby-grade track or club driving where repeatable rear alignment helps driver feedback and setup adjustments.
