These aluminium lock nuts are intended as replacement fasteners for small Mini 4WD components where vibration resistance is important. The nylon insert provides additional locking force to help prevent nuts backing off on roller and damper posts, and the aluminium case reduces mass compared with steel options.
They are compatible with Mini 4WD PRO and standard Mini 4WD cars, serving routine maintenance and part replacement roles rather than delivering chassis-level performance gains. Always check thread engagement and avoid excessive torque on thin shafts.
This five-piece set is a practical, corrosion-resistant option for securing rollers and mass dampers during maintenance, racing practice and static setups.
