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

Aluminum motor mount for trail crawling

This motor mount plate, sold as JR-TRX402-BK, is produced by Jazrider for TRX-4 named applications. The machined aluminum plate is intended to position the motor and mate with the transmission area, offering a stronger mounting point than typical stamped or composite alternatives.

Suitability is tied to the TRX-4 naming in the title; confirm the chassis' screw pattern and motor placement before assuming fitment. The description does not guarantee interchangeability with non-TRX-4 chassis unless the mounting geometry and screw locations are compatible.

Installing the plate generally involves removing the motor and original bracket, transferring the motor and any shims, then bolting the new plate into the original screw holes. Take care aligning the motor pinion with the spur to prevent tight mesh or binding—this component is a tuning aid for alignment rather than a drivetrain overhaul.

As an aluminum accessory for scale and trail vehicles, the plate helps with heat dispersion and increases rigidity at the motor mount; inspect screw torque and mounting holes for signs of wear after demanding runs to preserve alignment.
