GPM TRAXXAS TRX4 Motor Heat Sink 6061-T6 TRX4018 - RC Spare Part  [TRX4018]

Cooling upgrade for TRX4 motors

This scale motor heat sink is made to fit the TRAXXAS TRX4 TRAIL CRAWLER platform and helps control motor temperature during slow, technical crawling. The finned profile boosts surface area to disperse heat more quickly without needing to modify motor internals.

Machined from 6061-T6 aluminum, the component resists bending and gives a stable mounting surface to help keep the motor aligned under load. The kit includes stainless steel flat head screws 3x8, 2 pcs for secure attachment to the motor or motor housing as designed for the platform.

From a tuning perspective, adding this dedicated heat sink reduces thermal buildup during extended low-speed running, helping the motor maintain consistent performance on technical sections. Check alignment before final tightening and monitor motor temperature after installation to confirm cooling benefits.
