TRAXXAS TRX4 Aluminium Double-Sided Motor Mount Plate with Fins TRX4018L by GPM  [TRX4018L]

Motor mount upgrade for TRX4 trail rigs

This aluminium double-sided motor mount plate is designed for TRAXXAS TRX4 Trail Crawler models. The plate features heat sink fins on both faces to increase surface area and assist passive motor cooling during sustained crawling.

The maker details a 13mm nominal thickness, 8mm more than the original part, intended to raise rigidity and nudge the motor forward slightly for improved low-speed traction and balance. The set ships with stainless steel flat head screws 3x14, 2pcs for the mount fixings.

Fitting is a direct chassis-level replacement of the original motor mount while keeping the motor and gearbox arrangement. The additional stiffness and heat sink mass reduce motor deflection under torque, giving more predictable crawl control.

Always confirm clearance around the gearbox and motor before purchase and check fastener tightness after initial use to avoid loosening on rough terrain.
