JAZRIDER JR-TRX406-GU Aluminium Portal Housing Trail Edition  [JR-TRX406-GU]

Strength and Style for the Traxxas TRX-4 with Aluminium Housings

Upgrading a Traxxas TRX-4 with the Aluminum Front/Rear Outer Portal Drive Housing by JAZRIDER gives both practical strength and a smart gun metal look. Crafted from CNC-friendly aluminium, this housing improves structural resilience while keeping weight reasonable for trail performance.

Why aluminium improves drivetrain durability

Aluminium is prized for durability without excessive mass, which helps maintain vehicle balance while strengthening critical mounting points. The material also sheds heat better than some plastics, helping drivetrain components run cooler under sustained loads.

Build fit and trail readiness

The housing is designed for a snug fit on TRX-4 scale and trail crawlers, reducing movement and play in the portal assembly. That precise fit reduces routine adjustments and keeps your crawler ready for longer sessions.
