3Racing 3RAC-N20/SI Kyosho Mini-Z Lightweight Lock Nuts  [3RAC-N20/SI]

Reliable Lock Nuts for Mini-Z Setups

Small upgrades can change how a Kyosho Mini-Z feels on track. The 3Racing 2mm aluminium lock nuts fit MR-015, Mini-Z AWD, MR-01, MR-02 (MM), and MR-02 (RM) models and give a noticeable improvement in fastening security. Constructed from titanium aluminium, they combine strength with low mass to reduce the chance of loosening.

Material Advantages

Titanium aluminium delivers a useful strength to weight ratio that keeps rotating mass down while resisting wear. That makes these nuts suitable for frequent running and club level competition where dependability matters.

Fitment Across Mini-Z Variants

These lock nuts are compatible with MR-015, Mini-Z AWD, MR-01, MR-02 (MM), and MR-02 (RM), allowing a consistent fastener choice across multiple Mini-Z chassis types.
