Tamiya 1/14 Tractor Truck Centre Gearbox TRU018 with Heat Sink by GPM  [TRU018]

Steel-reinforced style centre gearbox for Tamiya 1/14

The TRU018 alloy centre gearbox is an aftermarket housing option for 1/14 scale Tamiya tractor trucks. Replacing the factory plastic centre gearbox, the aluminium case includes a heatsink face to assist heat transfer in the centre drivetrain during prolonged operation. The kit is supplied as two pieces and includes matching mounting screws for a direct swap.

Designed purely as an RC drivetrain upgrade, the aluminium housing increases structural stiffness and improves durability where hobbyists require a firmer join between front and rear. The unit retains the stock drive orientation and mounting points on compatible Tamiya models, so it fits as a direct aluminium alternative to the plastic original.

Fitting advice: remove the original centre gearbox after basic disassembly of the centre area then secure the alloy unit with the supplied screws. Check gear mesh and alignment following installation and perform a light run-in to confirm smooth operation. Only standard RC hex drivers are needed and thread locker use is at the owners discretion.

For model builders seeking a tougher centre section and improved thermal transfer at the heart of a 1/14 Tamiya truck drivetrain, this alloy gearbox supplies a direct-fit aluminium replacement as a 2pcs set with screws included.
