Tamiya 15205 - 1.4mm Hollow Propeller Shaft, Precision S.1/TZ Part  [15205]

Precision hollow shaft for S.1 and TZ Mini 4WD

The Tamiya 15205 1.4mm Hollow Propeller Shaft is made for use with the S.1 and TZ Mini 4WD chassis. Its hollow construction reduces rotating weight while retaining necessary strength, offering racers a targeted way to enhance drivetrain response.

Function and chassis fitment

Intended as a direct replacement for the conventional solid shaft on S.1 and TZ models, the hollow shaft cuts drivetrain mass to improve acceleration and steerability. It works alongside standard gearing to refine on-track behaviour rather than change gear ratios.

When to choose this upgrade

Choose the 15205 when you want incremental gains on twisty or technical circuits where quicker response and smoother transitions are important. Correct installation and routine checks will keep the part performing well over time.
