Traxxas TRX-4 Aluminum Rear Portal Drive Axle Mount by JAZRIDER JR-TRX405-GU  [JR-TRX405-GU]

Aluminum rear portal axle mount for TRX-4

This is an RC-scale rear portal drive axle mount designed for Traxxas TRX-4 chassis, finished in gun metal aluminum and produced under the JAZRIDER JR-TRX405-GU designation. The part replaces the rear axle mounting point for a portal-style drive assembly and is intended for scale trail and rock crawler setups.

The component's role is to hold the portal drive assembly in correct relation to the rear axle housing, helping maintain axle alignment under load and providing a metal alternative to standard materials. The construction and finish aim to match the mounting interfaces used on TRX-4 portal setups while keeping the profile suitable for scale trail use.

Installation notes: confirm fitment against your vehicle's rear portal interface and verify fastener positions before final tightening. Since this is a direct RC part, check existing mounting hardware and clearances with suspension travel and wheel offsets. For tuning, consider the mount as part of drivetrain geometry adjustments where axle alignment and secure attachment affect drivetrain behavior on technical trail sections.
