TAMIYA XV-01 Lock Nut Kit 4mm Low-Mass (5 pcs) - XV01-13407-LB by JAZRIDER  [XV01-13407-LB]

Overview of the XV-01 low-mass lock nuts

This kit contains five 4mm low mass lock nuts made for TAMIYA XV-01 scale RC cars. The nuts are aluminium with a light blue finish as delivered, and the listing uses XV-01 platform identification to show intended application.

These components act as retaining fasteners for wheel hubs and suspension linkages where weight reduction at rotating parts is targeted. Their low-mass character aims to reduce rotational and unsprung mass, which can influence steering feel and suspension reaction when tuning.

To fit, remove the original 4mm lock nuts from the XV-01 compatible mounting points and install these units, checking thread condition first. Tighten to an appropriate torque level so the joint is secure but not overstressed, and confirm fitment before active running.

Compatibility: TAMIYA XV-01 chassis.
