TAMIYA Tractor Truck Rear Gearbox CNC 14 pcs TRU013 by GPM  [TRU013]

High-precision aluminium rear gear box

This RC-scale aluminium rear gear box is a CNC-machined replacement housing made for TAMIYA tractor truck platforms, provided as a 14 pcs set TRU013. Manufactured from 6061 T6 aluminium, the casing improves dimensional accuracy compared with the standard plastic unit and assists in dissipating heat from drivetrain components.

The design supports both single- and double-shaft configurations commonly used on tractor truck models, with machining tolerances set to match original interfaces for a close fit. The kit includes the necessary fasteners for assembly: 3x14 Stainless Steel Button Head Screw - 8 pcs, and 3x20 Stainless Steel Button Head Screw - 4 pcs.

Install this part to gain a more rigid, thermally resilient rear housing that stabilises driveline mounting during extended operation; this is an aftermarket RC component and not intended for real vehicle use.

This GPM TRU013 aluminium rear gear box is a CNC-machined direct-fit upgrade for selected TAMIYA tractor truck models, improving case stiffness and thermal handling for greater drivetrain reliability.
