Practical Brass Portal Housing for Traxxas TRX-4 by JAZRIDER JR-TRX406-HD

The JAZRIDER JR-TRX406-HD Brass Heavy Duty Front/Rear Outer Portal Drive Housing is designed for hobbyists seeking a durable, user friendly upgrade to the Traxxas TRX-4. The brass outer shell adds mass low on the axle to help stabilise the crawler on technical sections without requiring internal gearbox changes.

Functional Weight Placement

Brass construction concentrates additional weight at the axle extremities, improving wheel contact and balance during slow speed crawling and steep climbs. This practical approach boosts traction where it is most effective.

Direct Fit, Minimal Installation Steps

Engineered for direct replacement on TRX-4 Scale and Trail Crawler models, the JR-TRX406-HD installs with common tools and original fasteners. No chassis modifications are required, making it a straightforward field or workshop upgrade.

Durability for Everyday Use

Robust brass material provides longevity for regular trail running. The heavy duty profile tolerates impacts and repeated use while delivering consistent handling benefits.
