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

Durability Notes for Rear Portal Mount

This black-finish aluminum rear portal drive axle mount is crafted as an aftermarket replacement for Traxxas TRX-4 scale trail crawlers. It provides a rigid mounting location for the rear portal assembly and is offered for repair, restoration, or setup changes rather than as a performance upgrade claim.

Install this mount when an OEM unit is damaged or when you want a metal substitution for a more scale-accurate appearance. The aluminum construction improves resistance to wear compared with many plastics, but purchasers should confirm exact measurements and any included fasteners with the vendor before purchase.

Fitment advice: designed as a direct rear portal drive axle mount for TRX-4 platforms. Confirm that alignment and thread sizes match your axle housing during a trial fit, and inspect for proper clearance around suspension links and driveline parts. Consider how the mount material affects long-term wear when planning maintenance cycles.
