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

Trailer rear axle upgrade

This alloy rear wheel axle is a scale replacement for Tamiya Tractor Truck trailers. It acts as the trailer rear axle member, providing a firmer wheel mounting point and helping preserve alignment when towing. Intended for hobby model repairs and setup; not for use on full-size vehicles.

Compatibility is limited to Tamiya Tractor Truck trailer rear assemblies listed in the product title, so check your trailer's mounting arrangement before ordering. Installation usually involves removing wheels and hubs, sliding the axle into the trailer mounts, then securing with the existing hardware. Verify bearing and hub clearance to ensure smooth wheel operation and correct axial play.

Setup advice: alloy axles add stiffness relative to stamped steel, which may shift handling and load distribution. When altering suspension geometry or wheel offset, confirm there is adequate clearance from suspension brackets and body supports. Regularly inspect fasteners and the axle for wear during maintenance.

Use this axle to repair or enhance the trailer rear of a Tamiya Tractor Truck; pair with the right hubs and bearings, follow original torque guidance, and verify alignment after running.
