TAMIYA DF-03 Front Differential Upgrade DF03-08/HD by 3Racing  [DF03-08/HD]

Durable front diff shaft for DF-03

This front differential shaft is intended for the TAMIYA DF-03 chassis and is identified by model DF03-08/HD. Forged from steel as a heavy-duty alternative to the factory shaft, it is aimed at owners seeking increased longevity while retaining the ability to perform common gear changes on DF-03 variants like Dark Impact.

Installation mirrors the usual DF-03 front differential procedure: open the front diff case, remove the stock shaft, install the replacement, set proper gear mesh and backlash, and reassemble. The shaft is designed for compatibility with standard DF-03 front differential parts and should not require chassis modification when used with matching components.

For tuning use, the shaft supports routine pinion and spur swaps and internal diff setup changes; its robust steel material helps reduce wear under heavier loads or prolonged running sessions. This product is an RC model upgrade and not for use on full-size vehicles.
