RC drivers seeking a stronger drivetrain for the Tamiya DF-03 will appreciate the heavy-duty rear differential shaft by 3Racing. Designed with the Dark Impact in mind, this shaft uses precision surface profiling to lower mass while standing up to rough off-road running.
The 3Racing DF03-03/HD rear differential shaft balances toughness and lightweight trimming to cut rotational inertia, helping your rig accelerate more responsively and hold lines better on loose surfaces. It is an upgrade aimed at practical performance gains without excess weight.
The shaft fits the Tamiya DF-03 family and aligns cleanly with Dark Impact assemblies. Installation is straightforward and requires common hobby tools, so you can swap parts and return to the track quickly.
