TRAXXAS TRX-4 Motor Mount Plate, Aluminum Upgrade - JR-TRX402-BK by Jazrider  [JR-TRX402-BK]

Mount plate details for TRX-4

This RC motor mount plate is supplied as the JR-TRX402-BK replacement, manufactured by Jazrider for TRX-4 named applications. The aluminum construction is intended to locate the motor precisely and interface with the transmission area, providing greater stiffness than many stamped or composite mounts.

Fitment is specific to the TRX-4 designation in the title; do not assume interchangeability with other chassis without checking that the mount geometry and screw pattern match your vehicle's existing footprint.

Typical installation steps include removing the motor and original mount, transferring the motor plus any shims or spacers, and securing the new plate in the same screw positions. Ensure correct alignment between pinion and spur gears during reassembly to avoid excessive mesh or binding, as the plate is intended to assist with drivetrain alignment rather than replace other drivetrain components.

The aluminum plate also contributes to heat dispersion and mounting rigidity for scale and trail vehicles. Regularly check the tightness of mounting screws and inspect mounting holes for signs of wear to retain consistent motor positioning during off-road use.
