Traxxas TRX-4 Upgrade - JAZRIDER JR-TRX406-HD Heavy Duty Brass Front & Rear Portal Housings  [JR-TRX406-HD]

Stabilise Trail Performance with JAZRIDER JR-TRX406-HD Brass Portals

For trail drivers who need more predictable footing, the JAZRIDER Brass Heavy Duty Front/Rear Outer Portal Drive Housing JR-TRX406-HD adds valuable low-end weight to the Traxxas TRX-4. The extra mass helps the crawler during steep approaches and rocky moves.

Lower Centre of Gravity Improves Grip

The brass housings move weight down toward the axle ends, helping the vehicle keep contact on uneven lines and improving overall grip when tackling obstacles.

Straightforward Fitment for Hobbyists

Made as a direct replacement for the Traxxas TRX-4 Scale and Trail Crawler series, this part installs without cutting or custom fitting, letting you upgrade quickly between sessions.

Durable Choice for Regular Off-Road Use

Brass construction gives a reliable combination of heft and wear resistance for frequent trail running. The heavy duty build holds up to knocks and gives consistent performance.
