This product includes five 4mm low mass lock nuts designed for TAMIYA XV-01 scale RC cars. The nuts are constructed from aluminium and arrive in a light blue finish; the description ties them to the XV-01 platform as noted in the title.
Functionally they are used to secure wheel hubs and suspension linkages while keeping fastener weight low. Their low-mass design aims to reduce rotating and unsprung mass, which in turn can affect the model's responsiveness and suspension behaviour under tuning.
Fitting is direct: remove the existing 4mm lock nuts from compatible XV-01 mounting points and replace with these units. Confirm thread condition, tighten to a secure but not excessive torque, and verify the assembly before operating the model.
Compatibility: TAMIYA XV-01 chassis.
