Tamiya Tractor Truck Trailer Rear Axle Precision TRU074 by GPM  [TRU074]

Scale trailer rear axle replacement

This alloy rear wheel axle is an RC-scale replacement component for Tamiya Tractor Truck trailers. It provides a strong mounting point for trailer wheels and helps keep alignment under load for more consistent towing behaviour. The item is intended for hobby-grade maintenance and tuning, not for road use.

Fitment is intended for Tamiya Tractor Truck trailer rear assemblies as listed in the product title; verify your trailer layout before fitting. Installation generally requires wheel and hub removal, sliding the axle through the trailer mounts, and securing with the original fixings. While installing, confirm hub fit and bearing condition to ensure smooth rotation and correct endplay.

Tuning note: alloy axles add stiffness over standard stamped steel parts, which can alter load transfer and tracking. When changing suspension geometry or wheel offsets, check for clearance around nearby mounts and body supports. Maintain correct torque on fasteners and inspect the axle periodically for wear.

Fit this axle when servicing or upgrading the trailer rear of a Tamiya Tractor Truck; use compatible hubs and bearings, maintain recommended torque, and re-check alignment after the first outing.
