Tamiya DF-03 Rear Shaft Reinforcement DF03-03/HD by 3Racing  [DF03-03/HD]

Solid Rear Differential Upgrade for the DF-03

The 3Racing heavy-duty rear differential shaft gives the Tamiya DF-03 a more resilient rear drive. Suited to Dark Impact style layouts, machining removes unnecessary material to lower rotating mass while retaining core strength.

Better Drive Feel and Longevity

The 3Racing DF03-03/HD is engineered to reduce rotational inertia, which improves throttle response and corner exit consistency. It is a practical upgrade for racers who want a more reliable rear end without excess weight.

Compatibility and Quick Fitment

Designed for the DF-03 series, the shaft installs using common tools and does not require chassis alterations. It provides a tidy, direct-fit replacement for the stock part.
