Tamiya Tractor Truck Trailer Rear Axle TRU074 precision fit by GPM  [TRU074]

Precision rear axle for trailer assemblies

This alloy rear wheel axle is a scale replacement crafted for use on Tamiya Tractor Truck trailer rear assemblies. Designed with emphasis on fitment and rigidity, it provides a firm wheel mounting point to reduce deflection under load. The component is intended for hobbyist maintenance and tuning and is not intended for full-size vehicle use.

Confirm compatibility with the Tamiya Tractor Truck trailer rear layout before ordering. Installation involves removing the wheel and hub, locating the axle through the trailer mounting points, and securing with the original fasteners. During assembly, verify bearing condition and hub clearance to achieve correct endplay and smooth rotation.

Technical notes: the alloy construction increases torsional stiffness compared with typical stamped steel axles, which affects load transfer and trailer dynamics. When adjusting suspension parameters or wheel offsets, validate clearance around suspension mounts and body supports and maintain factory-recommended fastener torque values.

Select this axle for a robust, precision-fit rear assembly upgrade on Tamiya Tractor Truck trailers; pair with matched hubs and bearings and follow correct torque and maintenance practices.
