Kyosho Mini-Z MR-015 Titanium Differential Shaft - 3RACING KZ-07A Performance Upgrade  [KZ-07A]

Stronger Diff Shaft for Better Lap Times

RC racers who want a tougher drivetrain option for the Kyosho Mini-Z MR-02 will find the 3RACING KZ-07A a practical choice. Built for the MR-015 series, this titanium differential shaft raises durability while keeping the Mini-Z agile for tight circuit work.

Benefits of Titanium Construction

Titanium gives a high strength-to-weight balance that helps reduce rotating mass compared with heavier steels. The 3RACING KZ-07A shaft preserves reliability under load, which helps maintain consistent handling through long practice or race sessions.

Fitment and Simple Installation

The part is made to match MR-015 specifications and integrates cleanly into MR-02 builds with minimal adjustment. Installation follows standard Mini-Z differential procedures, letting hobbyists upgrade without extra machining.
