Tamiya Tracktor Scania R620 Compatible Gearbox Heat Sink Plate TRU018SC by GPM  [TRU018SC]

Alloy heat sink plate for Tracktor gearboxes

This RC-scale aluminium alloy heat sink plate is made to bolt to the gearbox housing on Tamiya Tracktor trucks and is supplied as a pair. The finned profile increases exposed surface area to help dissipate heat passively from the gearbox during extended indoor or outdoor running sessions.

The item is a thermal management accessory and not a substitute for routine gearbox service. It secures to the original gearbox mounting points and is intended to be used alongside regular checks such as gear mesh verification and bearing inspection. The aluminium alloy offers a balance of thermal conductivity and light weight for scale truck use.

Practical tuning note: fitting the finned plates can help stabilise gearbox temperature under continuous operation, which may reduce thermal-related performance change in motors and ESCs during long runs. This is a passive bolt-on upgrade that requires no wiring or electronic modification.

Choose these alloy heat sink plates when you want a simple bolt-on option to improve gearbox heat dispersion on a Tamiya Tracktor Scania R620 while keeping standard maintenance routines unchanged.
