The MX030 upgrade kit provides 7075-T6 aluminium knuckles and pull rods as an aftermarket option for LOSI PROMOTO-MX machines. The metal parts reduce steering flex and improve repeatability when adjusting suspension or steering geometry, while remaining installable with standard hobby tools.
The kit supplies larger inner bearing seats and includes four 4x10x4 bearings for direct swap. It is intended for LOSI 1/4 PROMOTO-MX motorcycle RTR models, including the PRO CIRCUIT edition, and is for RC use only.
