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

Machined aluminium rear gear housing

This RC-scale aluminium rear gear box is a CNC-machined replacement housing made for TAMIYA tractor truck platforms, supplied as a 14 pcs set TRU013. Fabricated from 6061 T6 aluminium, the housing improves dimensional accuracy over the original plastic part and helps reduce heat build-up around drivetrain elements.

Designed to accept common single- and double-shaft arrangements on tractor truck kits, the machining tolerances aim to align with original mating components for minimal play. Fasteners included make for direct assembly: 3x14 Stainless Steel Button Head Screw - 8 pcs, and 3x20 Stainless Steel Button Head Screw - 4 pcs.

Choose this upgrade when you need a tougher rear casing to stabilise the driveline mounting and manage sustained thermal load during long runs; this is an RC-only component and not for use on real vehicles.

This GPM TRU013 aluminium rear gear box offers a CNC-machined direct-fit replacement for selected TAMIYA tractor truck kits, improving case rigidity and heat resistance for more dependable RC drivetrains.
