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

Rear wheel axle for Tamiya trailers

This alloy rear wheel axle is an RC-scale replacement part produced by GPM for use on Tamiya Tractor Truck trailers. It serves as the trailer rear axle assembly component, providing a rigid mount point for wheels and helping keep alignment under load. The part is intended for hobby-grade model maintenance and tuning, not for full-size vehicles.

Fitment is limited to the Tamiya Tractor Truck trailer rear assembly as indicated in the product name; confirm your chassis layout before ordering. Installation typically involves removing the wheel and hub, fitting the axle through the trailer mounting points, and securing with the original fasteners. Check wheel bearings and hub fit while installing to ensure smooth rotation and correct endplay.

Tuning notes: an alloy axle adds stiffness compared with standard stamped steel parts, which can affect trailer handling and load transfer. When adjusting suspension or wheel offsets, verify clearance between the axle and surrounding components such as suspension mounts and body supports. Maintain proper thread torque on fasteners and inspect the axle during routine maintenance for signs of wear.

Use this axle when repairing or upgrading the trailer rear end on a Tamiya Tractor Truck. Pair with correct wheel hubs and bearings, follow original mounting hardware torque, and re-check alignment after first run.
