TRAXXAS TRX-4 Heavy Duty Portal Drive Housing Upgrade JR-TRX406-HD-V2 by Jazrider  [JR-TRX406-HD-V2]

This outer portal drive housing is crafted for the Traxxas TRX-4 axle layout and carries the model designation JR-TRX406-HD-V2. Supplied in black, it replaces the outer portal shell on either front or rear axles to provide a more rugged external housing option for scale and trail-focused vehicles.

Use case: intended for TRX-4 variants that accept outer portal housings. It is marketed as an aftermarket housing piece rather than an entire axle, so verify your axle compatibility prior to purchase.

Assembly notes: transfer internal components like bearings and seals from the OEM housings when fitting this replacement. After installing, check alignment and retorque fasteners to safe values. The outer case can affect ground clearance and driveline line-of-sight.
