TRAXXAS TRX-4 Heavy Duty Front/Rear Outer Portal Drive Housing by JAZRIDER JR-TRX406-HD-V2  [JR-TRX406-HD-V2]

This is an RC-scale outer portal drive housing designed for the Traxxas TRX-4 chassis and offered under the JAZRIDER model JR-TRX406-HD-V2. The part replaces the outer portal housings at the front or rear of the axle assembly and is supplied in black finish as a direct-style upgrade option for scale and trail crawler builds.

Intended role and fitment: the housing is intended for use on TRX-4 portal axles where users need a heavy-duty external housing for their portal gear setup. It clarifies fitment to TRX-4 variations that accept outer portal drive housings, and it is presented as an RC spare/hop-up rather than a complete axle assembly.

Installation and tuning notes: this component is a direct replacement type part that typically requires transferring existing internal components such as bearings and seals from the original housings. Check axle alignment and re-torque fasteners to factory values after assembly. Use as part of a scale or trail-focused setup where outer portal housings influence clearance and driveline geometry.
