Precision rear portal axle mount for TRX-4

This rear portal drive axle mount is made for the Traxxas TRX-4 chassis and finished in gun metal aluminum, identified by the JR-TRX405-GU designation. It provides a portal-style replacement for the standard rear axle mounting location for scale trail and rock crawler use.

The part holds the portal drive assembly in the correct relation to the axle housing to maintain alignment under load and offers a metal upgrade over typical stock mounts. The design focuses on matching the TRX-4 portal mounting interface while keeping a realistic scale appearance.

Installation guidance: check the rear portal interface dimensions and fastener placement before final assembly. Confirm clearance with suspension travel and wheel offsets, and inspect existing mounting hardware. When adjusting drivetrain geometry, account for this mount's effect on axle alignment and drivetrain loading.

How precise is the fit for TRX-4 portal kits?

This mount is machined to align with common TRX-4 portal interfaces, but measure your chassis pattern to ensure full compatibility before purchase.

Will this affect drivetrain tune or gear mesh?

Yes; changing mount geometry can alter driveline angles and gear engagement. Check gear mesh and driveshaft alignment after installation as part of tuning.

What should I inspect after fitting?

Confirm all bolts are correctly seated, recheck clearances during suspension travel, and perform a short test run to watch for abnormal drivetrain noise or binding.
