The Kyosho MZW209 Titanium Ball Differential Shaft is intended for drivers who want tighter handling from their Mini-Z MR-03 class models. Precision engineered from titanium, the shaft lowers rotating mass to make throttle inputs more immediate and steering reactions crisper.
Titanium is chosen for upgrades because it pairs high strength with low weight, preserving component life without the penalty of extra mass. This improves rotational efficiency in the driveline while remaining robust under race use.
Designed to suit Kyosho Mini-Z MR-015, MR-02 and MR-03 platforms, this differential shaft fits as a direct replacement. It is a practical upgrade for racers refining balance and acceleration behaviour.
