TRAXXAS TRX-4 Aluminum Motor Mount Plate for Improved Rigidity - JR-TRX402-BK by Jazrider  [JR-TRX402-BK]

TRX-4 motor mount plate overview

This is an RC motor mount plate produced by Jazrider for TRX-4 named applications, supplied as the JR-TRX402-BK replacement part. The aluminum plate locates the motor and interfaces with the transmission area, delivering a firmer mounting point compared with common stamped or composite mounts.

Compatibility is limited to TRX-4 titled models; verify the screw pattern and motor footprint on your vehicle before assuming fitment. This description does not assert interchangeability with other chassis unless their mount geometry and screw layout match the TRX-4 configuration.

Installation normally requires removing the motor and the factory mount, transferring the motor and any shims or spacers, then securing the new plate in the original screw positions. Pay careful attention to pinion-to-spur alignment during reassembly to prevent excessive mesh or binding; the plate functions as a tuning aid for drivetrain alignment, not a full drivetrain replacement.

As an aluminum accessory aimed at scale and trail crawlers, the plate helps dissipate heat and increases mounting rigidity; check screw torque periodically and inspect mounting holes for wear after heavy trail use to maintain steady motor alignment.
