TAMIYA Tractor Truck Rear Gearbox 14 pcs 6061 T6 TRU013 by GPM  [TRU013]

CNC aluminum rear gear housing

This RC-scale aluminum rear gear box is a CNC-machined replacement housing made for TAMIYA tractor truck platforms, supplied as a 14 pcs set TRU013. Machined from 6061 T6 aluminum, the case provides tighter dimensional accuracy than stock plastic housings and helps disperse heat away from drivetrain components.

The unit accepts both single- and double-shaft arrangements common to tractor truck models, with machining tolerances set to align with the related original parts 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.

Fit this metal gearbox when you need a tougher, more thermally stable rear housing to steady driveline mounts and reduce thermal stress under sustained RC running; this item is an RC accessory only and not for real vehicle use.

This GPM TRU013 aluminum rear gear box provides a direct-fit, CNC-machined upgrade for compatible TAMIYA tractor truck kits, improving housing stiffness and heat resistance for more reliable RC drivetrain performance.
