Designed for use on the Traxxas TRX-4 platform, this JR-TRX406-HD-V2 outer portal drive housing fits at the front or rear axle and is finished in black. It serves as an aftermarket external case to improve exterior strength for scale and trail crawler rigs.
Intended application: suited to TRX-4 portal axle styles that accept detachable outer housings. It is supplied as a spare/hop-up part rather than a full axle, so check compatibility with your axle variant before fitting.
Fitting guidance: the housing is a like-for-like external replacement; internal parts such as bearings and seals are usually moved from the original units. After assembly verify axle alignment and torque fasteners to the recommended specification.
Offered as a heavy-duty replacement outer case for TRX-4 portal setups, this part targets builders seeking improved external durability and scale appearance.
