Tamiya 1/14 Truck Aluminium Centre Gearbox TRU018 Upgrade by GPM  [TRU018]

Aluminium centre housing for 1/14 Tamiya trucks

The TRU018 alloy centre gearbox is an aftermarket replacement for 1/14 scale Tamiya tractor trucks. It replaces the standard plastic centre gearbox with an aluminium housing and features a heat sink area to assist heat dissipation around the centre drivetrain during longer sessions. The unit is supplied as a 2pcs set with matching mounting screws to simplify the swap.

Made for RC-scale drivetrain use, the housing improves mechanical stiffness and durability so the front and rear sections couple more positively. The gearbox keeps the same drive orientation and mounting points as the original on compatible Tamiya models, so it is suitable where a direct aluminium upgrade is desired instead of the plastic part.

Fitting notes: basic disassembly of the centre section is required, remove the old centre gearbox then bolt in the alloy replacement with the included screws. Check and set gear mesh and alignment after assembly and run-in under light load to verify smooth engagement. Only common hex drivers are required and thread locking is optional based on your servicing plan.

For modellers seeking a more robust centre section and improved heat handling in a 1/14 Tamiya truck drivetrain, this alloy gearbox is a direct-fit aluminium replacement supplied as a 2pcs set with screws.
