Traxxas TRX-4 Portal Axle Outer Housing — Brass Heavy Duty - JR-TRX406-HD by Jazrider  [JR-TRX406-HD]

Heavy Brass Portal Housing for TRX-4

The JR-TRX406-HD front/rear outer portal drive housing is supplied as a brass replacement for Traxxas TRX-4 portal assemblies. It functions as the external outer shell for portal axles and is intended to replace factory units on compatible TRX-4 scale and trail crawler setups.

Made from heavier gauge brass, this housing increases structural stiffness and gives a metal finish preferred by many scale builders. The part alters how the portal assembly mounts to the axle and is typically chosen to enhance longevity and visual authenticity at both front and rear corners.

Fitting guidance: remove the existing outer portal housings and fit this brass unit to the matched portal gear assembly on the TRX-4 chassis. Confirm clearance with brake components and suspension links, check thread engagement, and set the gear mesh carefully after assembly to avoid binding.

This brass outer portal housing is a suitable metal upgrade for builders wanting a heavier, more durable shell; always verify fit and clearances with your TRX-4 portal assembly during installation.
