TAMIYA Tractor Truck Aluminum Rear Gear Box 14 pcs set by GPM TRU013  [TRU013]

Aluminum rear gear box for tractor truck

This RC-scale aluminum rear gear box is a CNC-machined replacement housing designed for TAMIYA tractor truck platforms, provided as a 14 pcs set by GPM TRU013. Machined from 6061 T6 aluminum, the casing offers improved dimensional accuracy over original plastic housings and helps with heat dispersion from drivetrain components.

The design accepts both single- and double-shaft configurations commonly used in tractor truck models, and the machining tolerances are intended to align with the related original components for a close fit. Included fasteners allow direct assembly: 3x14 Stainless Steel Button Head Screw - 8 pcs, and 3x20 Stainless Steel Button Head Screw - 4 pcs.

Use this part when you need a durable, metal wavebox casing to stabilise rear-end driveline mounting and manage thermal load in sustained RC runs; it is an RC accessory only and not for real vehicle use.

This GPM TRU013 aluminum rear gear box serves as a direct-fit, CNC-machined upgrade for compatible TAMIYA tractor truck models, providing a stiffer, more heat-resistant housing for RC drivetrain reliability.
