GPM Racing Aluminium Motor Mount Plate with Heat Sink Fins - 3pcs Set for Traxxas 1/10 TRX4 (TRX4018)

Technical motor cooling for TRX4 platforms

This CNC-friendly 6061-T6 aluminium heat sink is engineered for the TRAXXAS TRX4 TRAIL CRAWLER to provide passive thermal management during low-speed, high-load crawling. The fin geometry is optimised to increase convective surface area while avoiding any modification to motor internals.

Material choice and wall thickness deliver stiffness to resist deformation and maintain consistent motor-to-gear alignment under torque. The supply includes stainless steel flat head screws 3×8, 2 pcs for direct mounting to the motor or motor housing following the platform mounting pattern.

From an installation and setup perspective, confirm axial alignment and torque the fasteners evenly to preserve concentricity. Post-installation, validate cooling performance by logging motor temperatures during typical crawling runs to quantify the reduction in thermal accumulation.

This item is compatible with

• TRAXXAS TRX4 Defender Trail Crawler

What mounting pattern is required for fitment?

The part is sized for the TRAXXAS TRX4 TRAIL CRAWLER motor mounting layout; measure hole spacing against the heat sink before installing to confirm compatibility.

How does the fin design aid cooling?

The finned profile increases exposed surface area and improves airflow contact, which enhances passive heat transfer away from the motor housing during prolonged low-speed operation.

Any recommended installation procedure?

Align the sink concentrically with the motor, hand-start the two 3×8 screws, then tighten evenly to spec. Run a controlled test and record motor temperature to verify effective thermal reduction. Write Product Review Please sign in your account before you can write any review. Sign In Close
