Traxxas TRX-4 Rear Portal Drive Axle Mount — Aluminum Black JR-TRX405-BK by Jazrider  [JR-TRX405-BK]

Installation Guide for TRX-4 Rear Portal Mount

This aluminum rear portal drive axle mount is an RC-scale replacement part made for the Traxxas TRX-4 chassis layout. Finished in black, it acts as the mounting point for the rear portal axle assembly and is intended for model-level maintenance, repair, or configuration work rather than performance claims.

Use this mount when replacing a worn or damaged rear portal part or when changing axle components to achieve a specific scale look. The mount is made from aluminum for increased stiffness and durability relative to stock plastics, but confirm exact dimensions and any included hardware with the seller prior to purchase.

Installation notes: this part is intended as a direct rear portal drive axle mount for TRX-4 applications. During fitment carry out a trial assembly to verify thread engagement and alignment, and check that the mount clears nearby components before final torquing. When tuning, pay attention to how the mount alters axle height and driveline geometry as that will affect handling at model scale.
