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

Performance Focused Lock Nuts for Mini-Z Platforms

For racers and tuners seeking dependable hardware, the 3Racing 2mm aluminium lock nuts are specified for MR-015, Mini-Z AWD, MR-01, MR-02 (MM), and MR-02 (RM) chassis. Manufactured from titanium aluminium, these lock nuts aim to provide consistent clamping force while keeping unsprung mass low, which supports repeatable handling characteristics.

Material and Functional Advantages

Titanium aluminium offers a practical combination of tensile strength and weight savings. In practice this gives improved wear resistance and a reduced likelihood of loosening under lateral loads, which matters when optimising setup and tyre performance.

Compatibility and Service Notes

These lock nuts are suitable across multiple Kyosho Mini-Z models including MR-015, Mini-Z AWD, MR-01, MR-02 (MM), and MR-02 (RM). For maintenance, check thread condition and locking function regularly and replace units that show deformation to preserve consistent wheel alignment.
