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

Trailer rear axle replacement

This alloy rear wheel axle is an RC-scale replacement part intended for use on Tamiya Tractor Truck trailers. It functions as the trailer rear axle assembly member, giving a more rigid mount for wheels and helping maintain alignment under load. The component is meant for hobby model maintenance and tuning only, not for real vehicles.

Fitment is specific to Tamiya Tractor Truck trailer rear assemblies as shown in the product title; confirm your trailer layout before purchase. Typical installation requires removing the wheel and hub, passing the axle through the trailer mounting points, then fastening with the original hardware. Inspect wheel bearings and hub fit during assembly to ensure free rotation and correct endplay.

Tuning notes: an alloy axle increases stiffness compared with standard stamped steel parts and can alter trailer handling and load transfer. When changing suspension settings or wheel offsets, check clearance around suspension mounts and body supports. Keep fastener torque to specification and inspect the axle at routine service intervals for wear.

Choose this axle when repairing or upgrading the trailer rear on a Tamiya Tractor Truck; fit correct hubs and bearings, follow original mounting torque, and re-check alignment after the first run.
