Traxxas Kit Complete 2.56:1 Reduction RC Portal Axle Kit - 9843R

The Traxxas TRX9843R Portal Kit is a complete portal axle upgrade for the Traxxas TRX-4, delivering a 2.56:1 gear reduction through raised portal hub assemblies. Portal axles reposition the axle shaft above the centre of the wheel hub, increasing ground clearance without lifting the chassis — a meaningful mechanical advantage for technical crawling. This kit is compatible with TRX-4 variants 97044-1, 97054-1, 97064-1, and 97074-1, making it a direct-fit option for owners of those specific models looking to add portal axle geometry to their build.

Key Features

• 2.56:1 gear reduction built into each portal hub, multiplying torque at the wheel for steep or loose terrain
• Portal axle design raises the differential above the wheel centre line, increasing chassis ground clearance without a suspension lift
• Complete kit covers all four corners of the TRX-4 for a full portal axle conversion
• Direct fitment for TRX-4 models 97044-1, 97054-1, 97064-1, and 97074-1 — no modification required for compatible builds
• Traxxas-engineered components designed to integrate with the existing TRX-4 driveline and electronics
