TRAXXAS TRX4 TRAIL CRAWLER Aluminum Motor Heat Sink by GPM TRX4018  [TRX4018]

Aluminum motor heat sink for TRX4

This RC-scale aluminum motor heat sink is produced for the TRAXXAS TRX4 TRAIL CRAWLER platform and intended to manage motor temperature during slow-speed crawling and technical trail driving. The design uses a finned profile to increase surface area and promote faster heat dispersion without changing motor internals.

Constructed from 6061-T6 aluminum, the part resists bending and adds a stable mounting surface to help keep the motor aligned under load. The package includes stainless steel flat head screws 3x8, 2 pcs for securing the heat sink to the motor or motor housing as intended by the platform design.

In tuning terms, fitment of a dedicated motor heat sink like this reduces thermal build-up during extended low-speed operation, which can help maintain consistent motor behavior on technical sections. Verify alignment before final tightening and monitor motor temperature after installation to confirm the expected cooling effect.
