TRAXXAS TRX4 Finned Motor Heat Sink 6061-T6 TRX4018 by GPM  [TRX4018]

Motor cooling solution for TRX4 crawlers

This aluminium motor heat sink is produced for the TRAXXAS TRX4 TRAIL CRAWLER and is aimed at managing temperatures during slow-speed rock crawling and technical sections. The finned design raises surface area to encourage faster heat transfer without altering the motor itself.

Built from 6061-T6 aluminium, the part resists deformation and provides a firm mounting face to help keep motor alignment stable under torque. The supply includes stainless steel flat head screws 3x8, 2 pcs for fastening the heat sink to the motor or motor mount as intended by the platform design.

As a tuning item, a dedicated heat sink like this helps reduce thermal build-up during prolonged low-speed work, which supports steadier motor output in technical terrain. Ensure correct alignment before final torque and check motor temperature after installation to confirm the cooling effect.
