Tamiya 54343 - Lightweight Freewheel Axle Pair for M-Chassis (M-03/M-05)  [54343]

Upgrade M-Chassis Drive with Lightweight Freewheel Axles

The Tamiya 54343 Lightweight Freewheel Axle Set gives M-Chassis fans a compact, performance-minded upgrade. The kit includes two precision aluminum axles that are light yet robust, making them an effective swap for M-03 and M-05 models looking for crisper response on the track.

Why aluminum works well on freewheel axles

Aluminum provides a strong strength-to-weight balance, so you lose less mass at the wheel ends while keeping durability. Fitting lighter axles can help your model accelerate quicker and react more sharply under driving inputs, which is useful when lap times matter.

Fitment notes and simple installation

These axles are designed to fit Tamiya M-03 and M-05 chassis with minimal modification. Installation is straightforward for hobbyists familiar with basic disassembly, letting you get back on the track with little downtime.
