Alloy rear knuckles built for TT-02B and DF-02 platforms

These gun metal aluminium rear knuckle arms replace the stock plastic components on Tamiya TT-02B and DF-02 chassis, offering a more rigid hub mounting while preserving the factory geometry. The alloy finish provides a durable upgrade without compromising fitment.

Installation follows the original chassis layout: remove the plastic knuckles and install the aluminium replacements using the existing hinge pins and hardware. No significant modifications are required for standard builds, but always check clearance with aftermarket wheels and bulkier tyres.

Functionally, aluminium knuckles limit flex at the pivot and can deliver a firmer rear steering feel along with steadier rear toe under dynamic loads. That makes them a useful upgrade for drivers wanting improved part life and repeatable setup changes.

Will these fit directly onto TT-02B and DF-02 without mods?

Yes, they are manufactured to fit the stock mounting points on Tamiya TT-02B and DF-02 chassis and typically install without modification.

Do aluminium knuckles require special maintenance compared to plastic?

Aluminium is more robust but still benefits from periodic inspection of hinge pins and mounting faces to prevent wear and ensure consistent performance.

What performance gains should I expect after fitting these?

Expect reduced rear hub flex, improved steering precision, and more consistent rear toe under load, which helps when fine tuning setup for track or club runs.
