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

Finned alloy plate for Tracktor gearboxes

This two-piece aluminium heat sink plate is engineered to attach to the gearbox housing on Tamiya Tracktor truck models. The fin array expands the surface area and helps disperse heat passively during long driving sessions.

The part is intended as an accessory for model-level thermal control and is not a substitute for internal gearbox servicing. It secures to the existing gearbox mounting points and should be used in conjunction with routine maintenance tasks such as gear mesh checks and bearing inspection. Aluminium alloy was selected to balance thermal performance and weight for scale truck applications.

Usage note: installing the finned plates can stabilise gearbox temperatures under prolonged operation and may reduce heat-driven changes in motor and ESC performance during scale truck runs. The upgrade is passive and requires no changes to electronics or wiring.

Fit the GPM TRU018SC aluminium plates when you need a straightforward bolt-on solution to improve gearbox heat dispersion on a Tamiya Tracktor Scania R620 while maintaining standard service routines.
