Tamiya M03/M03M Heavy Duty Wheel Axle M03M-15/HD for Touring by 3Racing  [M03M-15/HD]

The PRO-spec wheel axle, model M03M-15/HD, fits Tamiya M03 platform cars and is offered as a heavy duty replacement for competitive touring and practice. It covers M03, M03M, M04, M05 and M06 PRO variants.

Designed to take the place of stock wheel axles, this part reduces flex under load to help keep wheel alignment stable during hard cornering or long runs. Confirm compatibility with your hubs and wheel hexes before installation; the axle interfaces with chassis hardware but does not affect electronic systems or transmission gearing.

As part of a tuning progression, this axle acts as a stiffness upgrade where wheel movement compromises handling. Perform routine checks for wear and secure fasteners after impacts to maintain consistent hobby and club track operation.
