Feature notes and installation

The unit uses a bearing and delrin collar so the mass is concentrated lower on the wheel while still allowing free pivot motion. That geometry improves ground contact and helps the vehicle clear obstacles at steeper angles without losing roll control.

Specifications

Weight: 128 grams (excluding bearings and collars)
Hex Widener Size: 31mm for Traxxas TRX-4, 21mm for Axial and GMADE models
Wheel Compatibility: Inner diameter 45mm, wheel shaft hole 5mm

A no-fuss upgrade favoured by rock crawlers who want improved traction and steadier handling on technical lines.
