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

Aftermarket motor heat sink for TRX4

This aftermarket aluminium motor heat sink is aimed at the TRAXXAS TRX4 TRAIL CRAWLER and helps manage motor temperature during crawling and slow trail runs. Its finned profile improves surface area for better passive cooling without modifying the motor internals.

Forged from 6061-T6 aluminium, the component resists bending and provides a solid mounting platform to keep motor alignment stable under load. The kit ships with stainless steel flat head screws 3x8, 2 pcs for securing the sink to the motor or housing per the platform mounting layout.

When tuning for sustained low-speed performance, fitting a dedicated heat sink can reduce thermal buildup and help maintain consistent motor behaviour on technical sections. Always check alignment before final tightening and monitor temperatures during initial runs to verify the expected improvement.
